This is an update for my “BIP” noise machine – a swallowable microphone. Since this concept seems infeasible technically (I researched “swallowable telemetry capsule” to no avail), I intend to build something more modest that still addresses bodily noise. To that end, I’d like to build a personal stethoscope, where the bell (the hollow cup) is made to be affixed roof of one’s mouth using an adhesive pad.
My updated concept relates to Andre Borges’ 2011 performance “Inside-Out” (Chris posted this to the blog a few days ago), in that it uses the human body as a source of sound.
I am interested in the introspective potential of this device for individual users. I’d like the inside of the mouth to become a laboratory for acoustical experimentation, beyond just a functional passage for food. So if this is to be a personal noise machine, I think the formfactor should be subtle rather than attention grabbing. The listening component of the device could be as “simple” (conceptually at least) as a pair of earbuds with a transducer at the end.
• How do I power the transducer and attenuate the signal it produces? I don’t want anyone to go deaf using this!
• How can I ensure that the transducer is sanitary to put in a mouth? Where does one store the transducer-end of the device when they aren’t using it?
• How can I design the transducer-end such that eating and talking are possible?
• How can I reduce the risk of distortion, if the transducer is in close proximity to the sounds being made?
• Is this really a noise machine? If not, how can I make it more like one?
