Chapter 11: Sound 

________ can be used to treat certain medical problems.

________: the process of locating objects by emitting sounds and interpreting the sound waves that are reflected back.

________: how high or low a sound seems to be.

________: a spiral- shaped structure that is filled with liquid and contains tiny hair cells.

________: a system that uses the reflection of underwater sound waves to detect objects.

The ________: The change in pitch or wave frequency due to a moving wave source.

When the eardrum vibrates, it passes the sound vibrations into the ________, where three tiny bones start to vibrate.

________: a hollow chamber filled with air that amplifies sound when the air inside of it vibrates.

________: the human perception of sound intensity.

________: the amount of energy that flows through a certain area in a specific amount of time.

Every note has a different frequency, which gives it a(n) ________.

________: Each unit on the scale for sound intensity.

________: the study of sound.

When the membrane in the oval window vibrates, the sound vibrations are transmitted into the ________.

For a(n) ________, such as sound, the frequency is the number of compressions or the number of rarefactions that pass by each second.

Reflected ________ are used to detect and monitor conditions such as pregnancy, certain types of heart disease, and cancer.

A(n) ________ can hear sound waves with frequencies from about 20 Hz to 20, 000 Hz.

________ can travel through any type of matter- solid, liquid, or gas.

________: a vibration whose frequency is a multiple of the fundamental frequency.

________ can show the movement of winds in storms, and, in some cases, can detect the wind rotation that leads to the formation of tornadoes.

________: describes the differences among sounds of the same pitch and loudness.

It is the ________ that converts sound waves to nerve impulses.

________ also are used to break up and remove dirt buildup from jewelry.

For a(n) ________, amplitude is related to the density of the particles in the compressions and rarefactions.

________ can not travel through empty space.

________ influences how far a wave will travel because some of a waves energy is converted to other forms of energy when it is passed from particle to particle.
