Is there sound in outer space?

Organized sound can also be called what?

Any sound that has a random mix of frequencies

The loudness of a sound is measured in _______________.

Sound is a form of ________________.

Why is there no sound in outer space?

A particular set of frequencies at which any object vibrates is called it's:

A Note An Octave Higher Than A Given Note Will Have Twice The Frequency (Hz or VPS)

hollow body that reverberates sound waves produced by an instrument to make the sound louder

mutual reinforcement or cancellation that occurs when two or more waves meet

Reflection is when...

Pulses of compression makes a sound when a lip in the path has air flow over it, like a pipe organ

Percussion instruments are HIT or STRUCK to make a sound.

A sound of definite pitch when produced by a singing voice or an instrument

What is the disappearance of a sound wave into a surface?

A wavelength is...?

Strength of a sound is called...

The speed of sound depends on the ____________ through which it travels.

The closer a sound gets, the higher the pitch. The further a sound gets, the lower the pitch. 

What types of interference are there?

sounds at a higher frequency than the fundamental

The SI unit for frequency is the ___.

What is a waves amplitude?

a musical instrument's distinctive sound quality

What is reverberation?

Oscillation motion is moving in a arc to and fro.

Moving back and forth at a regular speed

Effect of soundwave strength on the way the human ear perceive sound

change in a wave's direction when passing from one substance into another

What is Diffraction?

A sound wave is a ___________________ wave.

Subsonic is slower than the speed of sound

What is Sonar used for

What is the name of this brass musical instrument?

What is the most widely played instrument in the US?

violent compression pulse caused by an object moving faster than the speed of sound

________________ is how well a sound can be heard.

The loudness of a sound is measured in _______________.

A loud noise caused by a shock wave

The change in the course of a wave as a result of a collision with an object

the most dominant sound produced when a musical instrument plays a single note

The finding of an object using reflected sound is ________________.

What is a sound that reflects off mediums, back to where it came from?

What is the measure of time for one wave to pass?

An interval is the distance between two notes.
