The electric buzz, without the shock

Mains' hum or electric hum is a sound associated with alternating current at the frequency of the mains' electricity. Electric hum has 60 Hz fundamental frequency in the US or 50 Hz in the EU, and a lot of harmonic content above. The fundamental frequency creates the hum (the brown slider), and harmonics create the buzz (the other sliders, the blue and purple in particular).

This noise came from a user's request, associated with a particular experience. Jenny writes:

"You are sitting at school and while the teacher blabs away about stuff you don't really care about, you stare up at the ceiling and get lost in the sound of the light. It buzzes in a medium monotone and it almost sounds like a fly or bee buzzing around. But it's a light and it makes you feel more comfortable than a bug. You know that some street lights do this as well, in different tones with each one. This is why you sometimes spend the day at a friend's, and walk home at night. You love this sound so much and sometimes you wish you could hear it all the time."

Don't forget to turn off the lights when leaving the room, Jenny.

  If this is really 50Hz, this could be used for therapeutic purposes. I think the reason people like this noise is partly because its frequency is known to lower blood pressure, which is nice.

  I prefer this frequency than the one we have here. What we have is 60hz. This makes me miss my freezer and air conditioner in Singapore that makes this kind of noise.

  Wow. I was curius so put all the sliders to the maximum. It feels like there's electric flowing through my brain. Sounds so strange, I like it though, not sure why.

  Sounds like a great big substation with the big transformers, and the insulators buzzing, 380KV maybe? Anyway it helps me sleep in transformer mode.

  I like this, though I'm unsure why :o It's quite peculiar too, there's a transformer at my university which has this perfect hum along tone, but neither the US, nor the EU version seem to be as easy to hum along with :o They still sound very lovely though!

  Helps me focus a lot, thank you!

  It helps me when I'm stressed out or not being able to think straight.

  Absolutely marvelous sound... some may find it annoying but it calms me down tremendously.

Usage

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.
