iPhone noise study

September 15, 2009

I love finding interesting sounds in the mundane. The other day on my commute back from work in New York, I plugged my mostly dead iPhone into the socket near my Amtrak seat, and hooked up my headphones in preparation for finding something long and interesting to watch on youtube. As I fumbled around on youtube, i noticed a very quiet noise coming through the headphones. I thought I must have accidentally engaged the iPod app, and was now listening to some of my music. I paused to try and descern what it was. I thought it could be Kevin Drum, or possibly one of the sessions on flat grey marked suspended pole holds tree. So I continued to listen, but could not identify the source, which I happened to be enjoying very much.

So I clicked over to the iTunes, and the sound changed. So I clicked on something else, and it changed again. I then realized that the sound was coming not from iTunes but from the device itself. So I grabbed one of my everpresent recording devices, plugged in, and began recording.

While recording, I played around with the different apps and things to investigate how the might change the sound. The sounds are screeches, clicks, bursts of white noise, little rumbles, and some almost turntablist sounding scratches. Playing with the touch screen affects the types of sound made, the volume, and the variation in pitch. In general though you can’t control these discretely, orvery precisely at all. It’s still fairly addictive to play with tho. While certainly not mindblowing, there is a nice range of sounds you can make.

I imagine this is some kind of grounding issue, which really should not happen, but it’s so quiet, it really won’t disturb most users. It also only occurs when the powercord and headphones are plugged in.

This is a pretty nice little study to listen to, and i think i may try playing with this a bit more in the future to see if i can get more sounds.

Enjoy!
