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.

  The sound of a small substation seems relaxing to me.

  Reminds me of VHS audio distortions a little. I like it.

  This one is really nice — reminds me of space colony ships maybe?

  Stimulates my mind that causes me to go wild. Not all people share this effect.

  Reminds me of the transformers on the poles outside my childhood home. Also reminds me of the looms you could hear in the Russell Mills factories when I lived in Alexander City, Alabama.

  Electric fence... in Jurassic Park.

  I really like it. I don't know why...

  Reminds me of my redneck childhood. Faulty bug zapper. lol.

  Finally we have control over the modern world's prime annoying noise!

  Yes it sounds just like the power grid in the US. I have over 200 gigabytes of FLAC files recorded at 96kHz sampling rate from an earth dipole antenna and you can hear motors, energy saving bulbs, oil burner ignitors and air conditioners turning on and off. This is nice to have when I'm at a friends house and I forgot to bring the MP3 player with me.

  Reminds me of cicadas during summer.

  I call it "opposites" like +/- completely different yet oddly harmonic with each other. This one focuses on low and high frequencies while still getting a backdrop from the middle, its good for anyone who needs to relax and forget about the day, or like me helps to focus on homework.

  For some the buzz of a light is the most annoying thing in the world, but sometimes if they're at the right frequency, it can sort of give off a focusing environment, but I'll leave that for you to decide.

  Reminds me of a road trip through the desert. We stopped at a gas station and near it was a big substation that sounded just like this.

  So relaxing...

  So much cinematic potential. Could be used in a film as an electricity sound effect.

  This is just Street Light 1, but it reminds me of a fantasy I've had many times that calms me down really well! Thank you!

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.
