Within the 0-130 dB range, we can hear any …
Web7 apr. 2024 · The main function of the ear is to help in hearing. In our brain, the temporal lobe senses sound. Pinna directs the sound wave toward the eardrum through the auditory canal and the eardrum amplifies it. The vestibulocochlear nerve sends the sound wave stimulus to the temporal lobe and then we are able to hear the sound.
