How does it transfer the sound of your heart ? And wouldn’t it help death people hear better ?
In: Engineering
it is a simple machine , it is a long tube with a diaphragm/ thin drum skin covering the end. The air is trapped in the tube between your eardrum and the diaphragm at the end of the tube, so the vibrations/ sounds picked up by the part you put against a person’s chest are transferred right onto your eardrum.
It would help people hear better, but it is more dangerous than many other options because any enclosed pressure on the eardrum is dangerous.
