The stethoscope is a device used for listening to sounds produced by the body. Specifically the heart, lungs, intestines, and blood flow through arteries and veins. It is also used to listen to the sounds from a developing fetus.
The stethoscope can also be used to detect leaks in plumbing, listen for rodents in walls, automotive diagnostics, vacuum leaks, remote listening and recording, or as a hearing aid.
Be certain you understand the system requirements before purchasing. Read instructions below on how to use your iPhone or iPod touch as a stethophone.
Best results are achieved with an iPhone. You can achieve good results with the iPod touch 2nd generation using an external microphone, but extreme care is required.
