Bone Trandcuer For skull listening

Post by mctdotnet »

Hi All,
I am looking forward to build Bone conduction Transducer specifically listening through skull bones. What amplifier is best for this project? Do I need anything else, like batteries or power adapter. Please help me out.
Thanks
Raj

You do not need a lot of power for bone conduction. These couple rather effectively through the skull to your inner ear. Our 2.5W mono amp should be plenty: https://www.adafruit.com/products/2130 Due to the way bone conduction works, there is no real benefit to a stereo amp.

In any case, you will need some power supply. For batteries, a 3xAA battery pack would do nicely. https://www.adafruit.com/products/727
For a hard-wired solution, a 5v supply like this should be plenty: https://www.adafruit.com/product/1995

For use on your skull, the small one in the tutorial linked above is a good choice.
