Sound

Front

What is the cochlea?

Back

The cochlea is a fluid-filled, snail-shaped structure in the inner ear that contains hair cells attached to nerves, which transmit sound information to the brain.

Front

What does low amplitude mean in sound?

Back

Low amplitude refers to a very quiet sound, indicating that the sound wave has less energy.

Front

What is the relationship between pitch and frequency?

Back

A sound with a low pitch has a low frequency, meaning the sound waves vibrate more slowly.

Front

Which part of the ear increases the amplitude of sound waves?

Back

The middle ear increases the amplitude of sound waves entering the ear.

Front

What are compressions in sound waves?

Back

Compressions are areas in a longitudinal wave where air particles are pushed together, creating regions of higher density and pressure.

Front

What is a sound wave?

Back

A sound wave is a longitudinal wave that travels through a medium (like air) and is created by vibrating objects.

Front

What is the outer ear?

Back

The outer ear is the visible part of the ear that collects sound waves and directs them into the ear canal.

Front

What is the function of the ear canal?

Back

The ear canal is a tube that carries sound waves from the outer ear to the eardrum.

Front

What is the role of the eardrum?

Back

The eardrum vibrates in response to sound waves, converting them into mechanical energy that is transmitted to the middle ear.

Front

What are rarefactions in sound waves?

Back

Rarefactions are areas in a longitudinal wave where air particles are spread apart, creating regions of lower density and pressure.
