From a design and functionality standpoint I am going to have to strongly disagree with this idea. Attaching an iPod dock to a stethoscope for heartbeat recording and playback is not the most efficient way of getting the task at hand accomplished. Why not slap on a flash drive that will record the sounds directly to, then you can easily put it on a PC to listen to quietly and amplify if necessary. Letting the Docs carry an iPod is just another 15 minutes you will have to spend waiting for them because they are catching up on the the latest episode of 24 on their iPod. It also adds a bunch of unnecessary wires to the stethoscope intimidating patients even more. Oh well, nothing I can do now. This iPod dockable stethoscope is available for $495.
