Homework Help: Amplified stethoscope?

  1. Sep 19, 2012 #1
    Hello, I am a student studying interdisciplinary sculpture. I am working on a project right now where I want the head of a stethoscope to connect to a speaker. I will need two of these, so at least two people can hear their hearts beating together at the same time. My idea is to have a rectangular column made of wood where I will embed the electronics/speakers. The stethoscopes and attached cords will come out of the column, enabling people to pick them up and use them.

    Is this possible?
    What kind of microphone can pick up the sounds from a stethoscope?

    The attempt at a solution:
    I have already searched the web for solutions and talked to teachers. So far I have not found a fool-proof solution. I have looked at acoustic and electronic/amplified stethoscopes. It seems that the best route will be to take the head of an acoustic stethoscope and embed a microphone into the tubing somehow which will then somehow connect to a speaker/microphone. Any help is greatly appreciated!

    I suspect it should be possible to connect the chest end of two stethoscopes to a single microphone using suitable tubing. Perhaps try a local pet shop or online for acquarium parts? I've purchased T joints from ebay in the past.

    Perhaps see also..
