I really like this. I use simplynoise's noise generators to drown out noise at work (oscillating brown noise usually) But I like having an equalizer. I've opened up multiple tabs and superimposed the noises, it downs everything out. Hope you can spare the traffic.

I built a noise generator around the concept of superimposing noises over each other [1]. I've consistently struggled with performance - at the moment it takes far too long to load properly. I'm planning to implement just-in-time loading when I get some free time

I don't really understand how it runs on iOS devices at all - to the best of my knowledge, it simply isn't possible to control device audio volume from javascript on iOS [1]. Or at least, that seemed to be the consensus last time I attempted to.

You can always reduce the volume in software before sending it to whatever API plays your sounds. This is especially easy if you're synthesizing the sound with the desired output volume known.

Needs Birdsong: http://www.bbc.co.uk/news/magazine-22298779 Everything feels better when listening to the Dawn Chorus.

There is something like this currently under development. There is a problem though: my noise generators are supposedly active across the whole hearing range, from 20Hz to 20kHz. And birds are only producing frequencies above 1000Hz. So, I need to fill up the bottom sliders with other sounds, or find... really big birds! ;-)

Fantastic. I tend to not like rain sound simulators, but the sliders let me pick one that seemed believable and familiar. I loved how the darker end of the spectrum let me simulate a visit to the Oregon coast.

(After which, I wished there was actually a storm right now, until I walked out onto my balcony and realized it was raining.)

"Too much internet for me" as they say.

Hi Guys! I am the developer of the myNoise website and just want to say that all your comments are a great source of inspiration today: many suggestions for further improvements will be taken into account! Although I did entirely code the website by my own using a simple text editor, I am not a programmer, in the sense that I never learned how to program efficiently and beautifully. Multiplatform issues, and mobile browsers in particular, are driving me crazy ;-) And yes... I feel a bit "naked" now as some of you are digging into my website code with much expertise. Please be indulgent! ;-) Cheers, Stephane
