I have a family history of sleep struggle, including a father who has a CPAP machine. This is what I do for sleep:

  • No alcohol.
  • Make my room as cold as it can be without freezing to death. Usually I set the temperature to somewhere in the 60's.
  • Turn on a fan to have continuous airflow/circulation/additional noise
  • White noise maker. This has been one of the best purchases, I use the Lectro Fan
  • Don't eat a few hours before sleep.
  • Don't nap. I used to randomly fall asleep in front of the TV for 30 minutes after a hard gym workout, but realized that it was making falling asleep at my normal time more difficult. I cut it out and force myself to stay awake until my normal sleep time. If I am tired that day I'll goto bed a little earlier than usual.
u/winteriscummming · 11 pointsr/oakland

Probably not the answer you want to hear, but do you use a white noise machine? I have a neighbor whose dogs bark all night long, and I finally picked one of these up on Amazon and it helps keep me sane. Lecteofan

u/EnglishSubtitles · 7 pointsr/Brooklyn

I second and third all the previous comments that suggest contacting your community board, city councilman and other elected officials.

Since you're the parent of a newborn, you need immediate help to improve the situation. So I suggest getting a white noise sound machine to help you and the kids sleep. Here's one I found on [Amazon]
(https://www.amazon.com/Adaptive-Sound-Technologies-LectroFan-Non-Looping/product-reviews/B00E6D6LQY) but there seem to be many good options. Good luck!

u/Mighty_Andraste · 7 pointsr/beyondthebump

Not sure if you’re set on music, but Lectrofan has 10 fan sounds and 10 colored noise sounds (white, brown, etc) - it has the option to turn on and play forever or you can set it for an hour if you want.

u/Snickershine · 4 pointsr/badroommates

I'm having motherfucking flashbacks goddamn.
Sounds just like the room mate I kicked out of MY apt last night because he wanted to stay an extra day because he's tired oh boo hoo.

Oh! And about the light! I too am a very light sleeper! I have all the good suggestions for you, friend!!! So, I have a noise maker.

Best one on the market, changed my gd life. My fiance snores. Even when she is quite loud, I just put it all the way up, right next to my head and I can sleep. Not the most comfortable way to sleep but I can still sleep!

I wear earplugs. Have since I was 11.
AAAND if I need to I wear a sleep mask. Soft thing. Takes a bit to get used to but it's so nice.
I use it every night because my fiance's fan light in her computer is bright green! So bright I can see it a bit through my eyelids! But it's okay because I have my nice mask!

God the more I read the more I nod my head. Mine was the same! Just seeing him made me seethe.
Now I would probably care some if he died. But I've had room mates where I did feel this way about. Bye.

He also chases after my fiance's exes and tries to run her friends off. So fucked.

One time he acted like her being in the hospital was an inconvenience and actually was arguing with me over text while I sat next to her hospital bed. And recently, my dog split her head open on the corner of a wall when she got scared and he SIGHED. Like this long sigh!! I couldn't believe it. Since that happened I have not been able to forgive him. We had to take her to an after hours vet because her poor head was POURING blood. Makes me sick to remember.

Who feels that way about an innocent animal? A bad person that I don't want to associate with anymore, that's who. Toxic, selfish fuck.

I bought a bunch, five and returned four when we broke our lease and moved. It was easy.

I hope it gives you some peace. I feel your pain.

u/lovedoesnotdelight · 3 pointsr/BravoRealHousewives

So I just moved to a new apartment yesterday in the same apartment complex. The building is brand new and the apartment is enormous. I knew it was too good to be true! I can hear literally everything. I can tell you exactly what my neighbors are watching and listen along with them. I can hear every time someone goes up and down the stairs. I had to call the leasing office to complain about the noise coming from above. Turns out they were cheerleaders practicing tumbling!

I need noise maker and reduction recommendations to drown this all out. My dog and I stressed and tired!!. I found this noise maker on amazon and thinking of buying two. Then I read tapestries or cloth on the wall really helps. I’m also going to get fans to go with the noise makers

Any other ideas??? I’m regretting my huge brand new apartment now and want my 30 year old 600 sq ft closet back!!:( I guess they don’t make them like they used to.

u/lafinass · 3 pointsr/polyamory

To drown out the noise in your room, the noise machine(s) would need to be in the room(s) where other people are, so it's going to depend a lot on what they like. Some people like cyclical fan noises, others like non-repeating white noise, others like deep humming or reverberation, but lots of people find such noises to be annoying or worse.

I personally love this thing: https://smile.amazon.com/Adaptive-Sound-Technologies-LectroFan-Non-Looping/dp/B00E6D6LQY/

I used it for years to drown out the sound of my cats meowing and scratching at the door. I found one of the settings on that machine blocked out most noise from outside the room and after an adjustment period I stopped really listening to the noise itself, it sorta dropped into the background.

The sound of it bothers my current NP so badly that she had to rush from the room after less than ten seconds. So be prepared for the possibility that no noisemaker is going to be a good option.

You may try instead to do some basic sound proofing. Soundproofing a room is expensive and labor intensive, but you can do a lot on the cheap to soundproof your bed itself to eliminate or reduce the squeaking/creaking/thumping. I bought a pack of rubber door jams and set them at strategic contact points between the base of our bed and the bed frame, which quiets all but the most violent of rocking motions. What works for you is going to depend a lot on your situation- both in how you have sex and what you're having sex on.

u/altoids1989 · 3 pointsr/WhitePeopleTwitter

I personally use the Lectrofan . I had a Dohm sound machine before, but since it's mechanical, it eventually became too quiet. The Lectrofan is smaller, has a better variety of noises, and can get much louder if necessary. It's easier to travel with too.

u/e67 · 3 pointsr/Dogtraining

I have 2 poodle mixes, and I also work from home, and these guys also bark at every freakin' noise in the apartment hallway. After years of trial and error, here is what works best for me; hopefully it'll work for you too.

  • white noise machine. They are super small and super cheap on amazon and it helps drown out both noise in the hallway and noise of them barking. plus the noise reduction on most phones/microphones take out the noise of the machine

  • desensitization - I've done a ton of this with them. Hell I even recorded the sound of the elevator door opening, and played that back to them non stop to desensitize them to the sound.

  • frozen raw bones - they love it. they'll chew that thing for at least 40mins with no sound, and it's good for their teeth

  • walks don't do anything.. i go to the off leash park and have them run around lots. bonus points if they wet, because their energy goes into keeping themselves warm, and they have less energy later for barking

  • I routinely put them in a room somewhere and shut the door, then I go into my room and shut the door. Between the noise machine (which I put by the entrance) and another door in the way, they can't hear much

  • I'm also super, super ashamed to say it, and it goes against all the best dog training knowledge and philosophy.. they they have vibrating collars that vibrate when they bark. Alone this doesn't work, but this little extra bit of positive punishment along with a ton of positive reinforcement (like the video above) seems to do the trick

  • I use a headset for when I'm on the phone, with a very accessible mute button on the cord. I'm on mute pretty much anytime I'm not talking.
u/Forty44Four · 3 pointsr/OkCupid

They get loud, and I generally sleep through shit all the time when it's on. I'd just check Amazon sales they usually go on sale pretty often.

u/mrdobalinaa · 3 pointsr/sleep

Try a white noise machine instead of headphones maybe? I can't hear conversations or the tv in the next room with this one.

https://www.amazon.com/dp/B00E6D6LQY

u/StrategicCarry · 3 pointsr/beyondthebump

I think you need to spend $50 to get a good dedicated white noise machine. The LectroFan here is very highly recommended, has lots of options (different fan noises as well as different white noises), and is pretty compact. https://www.amazon.com/dp/B00E6D6LQY?tag=thewire06-20&linkCode=xm2&ascsubtag=AwEAAAAAAAAAAOGr

If you want to keep using the YouTube videos, YouTube Premium is actually a decent service. For $15 a month you get the ability to download videos, but also no ads and YouTube Music (basically like Spotify). So if you watch a lot of YouTube, your kid is getting to the age where they might get some more screen time, and you're already paying for a music streaming service, it can be very worth it.

u/nosamiam28 · 3 pointsr/needadvice

Night shifter for almost 4 years here. Lots of good advice here. To emphasize and adding some more:

  1. Ambient white noise is a must. I bought a really good sound machine and it helps tremendously.

    LectroFan High Fidelity White Noise Machine with 20 Unique Non-Looping Fan and White Noise Sounds and Sleep Timer https://www.amazon.com/dp/B00E6D6LQY/ref=cm_sw_r_cp_api_Zv8dAbYHG0H79

    It’s pricey but worth it if you’re gonna be on this shift for a while. It uses randomly generated white noise instead of repetitive sound loops. The loops in cheaper machines are actually bad sometimes. I can hear the patterns and start involuntarily listening for them when I should be falling asleep.

  2. Block our as much light as you can. Even blacking out windows isn’t enough if the light creeps in around the edges. If there’s any light at all, wear an eye mask. You need to trick your body into thinking it is actually nighttime because light hitting your eyes makes your body manufacture cortisol, a hormone that wakes you up and keeps you up.

  3. Speaking of hormones, on the opposite end from cortisol is melatonin, the hormone that tells your body it is time to sleep. You’re body manufactures it, but it does so during the night. You need it during the day, so you need to supplement with oral melatonin supplements. You can get them over the counter. I prefer time-release but try some
    different dosages and release schedules till you find one that works.

    DON’T expect melatonin to work like a sleeping pill that knocks you out hard! It’s not that. You want something that isn’t habit-forming and basically makes you sleep like you would at night. Not drug you into a coma.

  4. If you’re really struggling, take Advil PM or ZzzQuil or even a shot of something (be careful with that one; it’s habit-forming and can make you have to pee a couple hrs later). Just use them sparingly to get through a rough patch or if you just feel desperate for some solid sleep. ALSO, don’t do this if you’ve been lying awake all morning and now don’t have time for a full sleep cycle. You don’t wanna be hung over when you wake up!!

  5. Take steps to prevent you from waking up in the middle of the day!!

    -Put your phone on silent. Do whatever you have to do so that the screen doesn’t light up when you get a text or whatever. Even through your eyelids, that light can trigger a cortisol rush and boom — you’re awake. Remember, you already have some cortisol on board. That light makes your body think the sun just came up and you don’t have enough melatonin to drag you back to sleep like you would at night.

    -Drink plenty of fluids during your shift, but cut off all fluid intake early enough that you won’t wake up having to pee in the middle of the day. Same thing as above. Often, once you’re up you’re up and you don’t have enough mela to get you back to sleep.

    -If you have a problem with waking up hungry, have a little snack before going to sleep. But not fruit or soup or anything with a lot of liquid in it if you have the above problem.

    -If you have people in your life, insist that they respect your need to sleep and how difficult it is for you. To put it in perspective, when they wake you up at 12:00 to go shopping with them or ask you where the remote is, ask them how they think it would feel if you woke them up at 2:00am to do the same. And then turned on the light and left it on. Because that’s what is happening to your body when they do it.

  6. Keep a regular schedule if at all possible. Sometimes it isn’t but until your body develops some sleep flexibility it should be a priority.

  7. Nap if you can, have time, and feel the need. For a night-sleeper, a nap can make it hard to fall asleep at bedtime. But if you’re like me — always tired — a nap won’t hurt your ability to sleep later and may be what helps you make it through your shift and home without crashing your car.

    You’re gonna struggle sometimes. It comes and goes for me, even with taking most of the precautions above. Just be patient and don’t get anxious because anxiety kills sleep quality (anxiety also makes us manufacture cortisol).

    Best of luck! I hope you’re able to crack the code!

White noise, my friend. (There's also pink noise and brown noise, which is my favorite)

You could buy a noise machine:

u/Turdworm · 2 pointsr/insomnia

They make sound pillows.

They also make pillow speakers.

Of several styles.

They make sleep headbands with speakers.

Then there's noise machines.

I use a fan. lol

If you go for one of those other things, I'd shop around a bit. Those were just the first I found as an example. Not sure of quality.

u/SleepResearchCenter · 2 pointsr/sleep

Def recommend the LectroFan. Although now I have to travel with it because the silence in hotel rooms is deafening. I've heard you can detect the "loop noise" on the one you posted.

We bought and really like this one. Has a USB plug so you can use AC with a wall adapter or an external battery. Doesn't have an internal battery though. It's truly continuous and doesn't loop. Lots of different white (brown, etc...) And fan types.

Missed it myself as we were over there for a show already, but we have no problem hearing a lot of their events all the way in South Walkerville. I'm glad you have such a great attitude about noise pollution though, I guess. Hah

Anyway, if you ever want a white noise machine instead of having to run actual fans, this is the best one I know of

It's kind of pricey for what it is, but the best part is it can get LOUD, so it really masks noise. Maybe not fireworks so much, but the vast majority of other stuff depending on how close you sleep to it. It has one setting that basically sounds like a regular box fan.

u/Bdiddy14 · 1 pointr/Advice

As someone with two dogs and a cat in a small place, I understand where you're coming from. I am sensitive to noise, especially at night.


I purchased a LectroFan noise machine to use at night, but you could also use it during the day. There are multiple sounds to choose from and the volume is adjustable.

Purchase a few rugs for the floors to help minimize the noise from the nails. You could also look into the placement of her water dish. When my pets noisily clean themselves next to me, I make a "tsh-tsh" sound and they'll either stop or move to another area to continue.


You should really look at your own health situation and speak to a doctor/therapist about this. I know when I'm experiencing strong emotions or anxiety, the sound sensitivity is more present and frustrating. It seems like you have been struggling lately and it's okay to experience frustration, but you have to remind yourself that your pet isn't doing this on purpose and you can't take out your frustration on her.


I hope things get better for you.

u/DCSkarsgard · 1 pointr/fixit

Perhaps counterintuitive, but a whitenoise device may be helpful if you can’t block it. I have several and have walked out of rooms where one was on only to discover the neighbor is outside with their chainsaw or a car with it’s bass thumping is parked out front. I highly recommend the LectroFan, they make an even smaller version that is $20 cheaper.

u/Slapbox · 1 pointr/Nootropics

I've actually read (though not sure if true) that more melatonin will actually worsen the situation.

The ideal dose is 0.5 to 1.0mg as I understand it.

MUCH more important though, darkness. It should be BLACK where he sleeps.

For 2-3 hours before trying to go to bed he should avoid all lights unless they're a very warm color. Blue light will affect his circadian rhythm. This is the case even in many blind people.

Key points:

  • Black room
  • Background noise. (Fan or Lectrofan)
  • Cool temperature
  • No white or blue light within several hours of sleep (To make screens redder, check out Lux for Android and Flux for PC)
  • Philips Hue light bulbs (These are mighty pricey, but for sleep, oh god. Controlling the color of the lights you surround yourself with will do a tremendous amount for keeping your circadian rhythm in check. I have gotten so much use out of these it's unbelievable.)
u/ManowarVin · 1 pointr/Fitness

why would your bf be opposed to good white noise?
oh, and don't go with the half price cheaper alternative... I did and then had to buy this because it's not loud.

u/vggeek · 1 pointr/buildapcsales

I got this one: https://www.amazon.com/LectroFan-Fidelity-Machine-Unique-Non-Looping/dp/B00E6D6LQY

Like the flexibility with many different white noises (the names are funny, I'm personally looking forward to cinnamon noise), and fan noises.

The same brand has one specifically for infants, which can be controlled with an app and has a night-light. It's an extra $20, which doesn't seem worth it to me, but letting you know.

There are several options in the $20 range instead (the one I linked to is $50), if you don't care about the different sound options. You're on your own however in picking between them haha

u/GrahamQuacker · 1 pointr/AskNYC

So, I just heard this white noise machine in an office waiting room and honestly it was amazing.

If you want one that helps for sleep, you actually probably want Brown Noise. It has lower frequencies than white noise, and I think there are studies that those lower frequencies genuinely help with sleep.

The link I posted has a great, deep, brown noise setting that makes you feel like you're on a private jet over a tropical ocean and have just taken your first Valium.

Important: do no confuse with the brown note.

They produce a white noise that can help you sleep. I have tinnitus and use them. Better than trying to sleep with earphones on. I can't imagine dealing with wires connected to my head for the rest of my life while I sleep. Understand what I mean?

Here are mine:

  • Secure Beginnings Crib Mattress - a totally breathable crib mattress. You can take the "sleep surface" off and throw it in the washing machine when needed. I surprisingly don't do it that often. The mesh fabric and space under it helps in temperature regulation and air exchange. Basically, helped me as a new mom not worry about suffocation. I ended up going wild and getting two sleep surfaces per mattress. I got one set in the regular size and a mini crib for our room.
  • LED Touch Light - these suckers are rechargeable and hold their charge a long time. They're super portable. What I like best is that you can turn them suuuuper dim, which is great for middle of the night wake ups and diaper changes. We have one hanging from our headboard and one hanging above the changing table. And then another around the house. There are tons of sellers of this type of product and they're quite inexpensive.
  • Wet Bag - a reusable and washable bag to stash wet/dirty stuff. An essential for cloth diaperers, but also great for pooped on clothes, bathing suits, etc.
  • Fischer-Price Ultra-Lite Day and Night Play Yard - this is a smaller and less expensive version of a traditional pack and play. We kept it in the living room and baby spent a lot of time there as a newborn.
  • Gripe Water Lots of gripe water. Good for gas, sometimes hiccups, and gentle relief for stomach upset. Also helps some newborns poop.
  • Grovia Magic Stick Diaper Balm - made for cloth diapers, but would work for sposies. A barrier "cream" on a stick, so you don't have to get your fingers gross. Smells amazing - I literally sniff the stick every time we use it.
  • Freemies - great for hands-free pumping, especially in the car or at work. Fits inside the shirt. Can be hit or miss on if it works for individuals, but it works GREAT for my boobs. Regular flanges hurt me and didn't yield good output, but Freemies agreed with my body wonderfully.
  • Spectra Pump I have nothing but good things to say about the Spectra pump. I have the S1 (battery operated), S2 (plugs in), and the S9 (battery operated, but not as fancy as S1). I haven't had any issues with my pumps, but others have had great customer service experiences. It's a "closed" system, which means it's impossible for milk to get into the pump on accident. This is a good thing.
  • Kiinde Storage Bags - these breastmilk storage bags are more expensive, but highly durable. I love the twist top - much easier to use then a zipper top. We used the whole bottle system from 0-6 months. At six months, he realized he could take the nipple off the bottle and we switched to Como Tomo bottles. But for those months, it was SO NICE to just send the bags to daycare and wash only the nipples (the shells stayed at daycare).
  • Lillebaby Complete Airflow Baby Carrier - while baby carrier preferences will vary widely by body type and personal preferences, I love my Lillebaby most. It doesn't require any special insert for newborns and the lumbar support was awesome. The airflow version was great, as I live in a very hot state.
  • Lectrofan Sound Machine - you may be wondering why this is $45 and other sound machines are $20. Because it is amazing, that is why. Seriously 100% amazing.

    Hope this helps somebody!

    Edit: added a few more after the Spectra.

I had a type of tinnitus that was two tones alternating irregularly. Very distracting. i used to crank up the stereo when I was commuting. Not sure if that was the cause but it calmed down when I got more responsible with the volume. I did use a white noise machine and it helped when the problem was severe. I used the sound of rushing air very softly and it was enough to mask the tinnitus. This is the one I used. I see there are cheaper ones but I know this one works well:
