Question

Sound is absorbed or observed by human ear ?

Answer 1

Answer:

Sounds reaching the tympanic membrane are in part reflected and in part absorbed. Only absorbed sound sets the membrane in motion. The tendency of the ear to oppose the passage of sound is called acoustic impedance.

Hey There ...


•Sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid.
•The outer ear directs sound waves from the external environment to the tympanic membrane. The auricle, the visible portion of the outer ear, collects sound waves and, with the concha, the cavity at the entrance to the external auditory canal, helps to funnel sound into the canal
