Types of sound waves
The Ear
Basic Facts
Parts of a Wave
100
A material through which a sound wave travels.
What is a medium?
100
Has a high frequency and high amplitude.
What is a high pitch and loud sound?
100
The three bones that make up the middle ear.
What are the hammer, anvil, and stirrup?
100
Sound travels through this medium 13 times faster than air.
What is a solid?
100
Part of a wave which determines the loudness of a sound and the amount of energy a wave has.
What is the amplitude?
200
The measure of how well a sound can be heard.
What is loudness?
200
Has a low frequency, but a high amplitude.
What is low pitch and a loud sound?
200
The part of the ear which stimulates nerves which send electrical signals to the brain so the sound can be recognized.
What is the cochlear?
200
Sound is this type of wave.
What is longitudinal/mechanical?
200
The top peak of a wave.
What is the crest?
300
How high or how low a sound is.
What is pitch?
300
Has a high frequency, but a low amplitude.
What is a high pitch and soft sound?
300
The part of the ear which funnels sound from your environment into the ear.
What is the outer ear?
300
Waves that do not require a medium to travel.
What are electromagnetic waves.
300
The lowest point of a wave.
What is the trough?
400
The unit use to measure the intensity of a sound.
What is decibel?
400
Has a low frequency and low amplitude.
What is a low pitch and soft sound?
400
The part of the ear which helps with balance.
What is the inner ear?
400
Waves that require a medium to travel.
What are longitudinal or mechanical waves?
400
The position of a wave when there is no vibration.
What is the centerpoint/rest position?
500
The apparent change in the frequency of a sound.
What is the Doppler effect?
500
True or false: frequency and intensity(loudness) are related
What is false?
500
The condition when damage is done to the tiny hair cells in your ear and you hear a ringing sound.
What is tinnitus?
500
True or False: sound waves never run out of energy.
What is false?
500
As frequency increases, this decreases.
What is wavelength?
