The hearing test helps in the evaluation of a person hearing ability. There are many features of the hearing test. The sounds we hear begin as vibrations in the air around our ear. And the vibrations produce sound waves, which vibrate at a specific resonance.
The vibration speed of a sound wave decides how high or low a sound is (pitch). A person starts hearing when these sound waves pass through the ear and then changes into nerve driving forces. These nerve driving forces are then sent to the cerebrum, which “hears” them.
