The best (harmless) way to calm fussy babies!

Much of the sound that reaches a foetus is a symphony of noises. The womb can be a very noisy place indeed, even in a quiet environment. These sounds help lull babies back to the very first place they found so comforting, fall asleep faster and sleep better.

The mother’s rhythmic heartbeat and breathing, the steady whoosh sounds of blood rushing through her veins, Mom's voice, her body movements, and the digestive process after lunch time are those noises that come to mind first. On top of that, we have all the sounds coming from the external world, filtered by the mother's womb as they reach the baby's ears.

We closely emulate them all, using the same gentle low-pass filtering that characterizes the mother's womb. This not only provides a faithful emulation of intra-uterine sounds, but also serves as a safeguard, protecting your newborn’s sensitive developing little ears against the harsh tones and higher frequencies.

  I love almost all of the sounds on this lovely website, but the gurgly sounds in In Utero somehow sound the same as when oil is applied on a stomach and rubbed when I there is too much gas in the digestive system. (These sounds somehow make me feel like vomiting.)

  One of my favorites! So soothing.

  Absolutely perfect.

  This is great with headphones. It feels really calming and like you're close to being a child again. The heartbeat is especially comforting.

  Just calm down to perfect peace with this.

  I don't know what happened, but when I tried the different sliders and I came across the 'Dad' one, I felt like I was gonna crying. It is so peaceful, like I could be a little girl again. It feels so peaceful and sad at the same time :')

  Thank you so much for creating this. First I thought that this is really weird cause I'm an adult, but as I regularly have mild anxiety attacks over literally everything I tried various relaxation excercises. And only this reminds me of the real situation: that I'm completely safe at the moment. I can now regain my energy and be able to tackle things the real way and focused.

  Perfect for vore fans! Sounds just like the inside of a womb or stomach <3

  At first I thought this generator was going to be a little weird, but once I got the settings right for me, it was wonderful! I have trouble sleeping, and I tried this wide awake at 3:00 am. Within minutes I was nearly asleep at my computer.

  This is amazing in a way that is difficult to explain...I have the heartbeat and breathing sounds up the highest and it really helps me feel calmer, more secure, and less alone (and I'm not a naturally calm person, so that's saying a lot). I'm a fetus at heart, I guess.

  This sounds like a nightmare.

  I absolutely love this, I have triedy so many but this is the one. Thank you so much for putting it out here for us. It's amazing!

  I may not be a baby, but I do have insomnia and listening to the heartbeat and breath sounds helps me to sleep.

  At first I didn't like this generator, but I gave it a try a try and it really works! The heartbeat and breathing is what really does the trick, but the other sounds make it not be too silent and weird. I personally like the water and 'bubbly' noises a lot.

  This combination closely resembles the act of putting ones head under a waterfall or more simply shower head... It plucks me from reality and drops me in trance like state I like to call my happy-dumb place

  The sound of a heartbeat helps me feel less isolated and the breathing stops me from hyperventilating. This page has rescued me from many an anxiety attack. Thank you.

  Even though I'm not a baby, this sound still helps me to sleep.

  By simply using the fourth slider and headphones, it sounds like you're swimming with your head underwater. It's like a dive into a peaceful world.

  Being underwater - whether in a bath or in a pool - always helps me feel better. It brings back confidence for me and helps calm my anxiety. This combination of noises is the closest I could come to actually being in the water, without taking a bath and holding my breath under it.

  I've finally found my quiet happy place.

  Do you remember?

  Although the 7th slider makes it seem a little eerie, it is a surprisingly soothing soundscape

  Sounds like something from a scary movie lol

  It reminds me of napping with my mom when I was little.

  This noise as it is -just heartbeat and breathing- is the most comfortable thing I've ever listened to.

  This is the greatest page I have ever come across. Love this.

  Submerged underwater is always where I feel most at peace

  I've been looking for something like this for a long time. The internal sounds of the body are very relaxing and cathartic to me. I just wish the digestion noises sounded less like bubbling water and more like actual digestion which is more grumbly and deeper, or even edit one of the sliders to add a second slider for digestion noises?

  Holding your breath underwater.

  The sound of being underwater and hyper-aware of your own breath and heartbeat. Oddly calming, and somehow nostalgic. With headphones on I easily mix up my own breaths and the simulated ones.

Each slider controls a particular audio stream. Adjust sliders to taste and mood.

Unlike the other sound generators, this soundscape is not calibrated. This means that sliders are not associated to exact frequencies and that the generator's output will not turn into a pink-like spectrum when sliders are horizontally aligned.

The Animate! button turns the soundscape into an slowly evolving texture. Use this feature if you intend to listen to the generator over a long period of time.
