How does it transfer the sound of your heart ? And wouldn’t it help death people hear better ?
In: Engineering
Same basic concept as putting an empty paper towel or gift-wrap roll up to your ear; sound waves are channeled right to your ear
Basically the sound waves travel through the air in the tubes to your ear from the end piece. It doesn’t amplify but it does isolate the sounds from the heart and lungs from external noise.
There are better amplified hearing aids for deaf people.
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.
