Choose the correct option (AS 1)

The sound waves if not focused by external pinna and ear canal will result in
A. Hearing several types of sound loudly

B. Not hearing anything

C. Slight hearing

D. Not being able to make out the type and origin of sound

Answer :

The sound waves if not focused by external pinna and ear canal will result in not hearing anything. This is because the ear pinna (external ear) functions to collect sound waves and focusing them to the ear drum through the ear canal. If the sound waves are not focused by the pinna then the sound waves would pass us without reaching the inner ear.
