Hair cells in the cochlea convert sound vibrations into electrical signals that are sent to the brain for interpretation.

The auditory nerve interprets electrical signals generated by the hair cells in the cochlea and transmits them to the brain, allowing us to perceive sound.

Understanding sound reflection helps in designing spaces with optimal acoustics, such as concert halls, classrooms, and recording studios, ensuring clear and balanced sound distribution.

Sound waves bounce off the surface, a phenomenon known as sound reflection. The angle at which they strike determines the angle at which they reflect.

The eardrum vibrates in response to sound waves, transmitting these vibrations to the middle ear's tiny bones, which then amplify and transmit them to the cochlea for further processing.

Sound vibrations cause the eardrum to vibrate, initiating the process of hearing by transmitting these vibrations through the middle ear to the cochlea in the inner ear.
