What property describes how HIGH or LOW a sound seems to a person?
pitch
The lower the frequency the what the pitch sound?
You're probably think of the Doppler effect, which is the change of the frequency of a signal depending on the motion of the observer relative to the signal source. The typical example involves a car horn and a person standing on the side of the road. If you are standing still next to a stopped car and its horn sounds, you will hear a certain pitch. If the same horn is sounded as the car is driving toward you, the pitch you perceive will be higher - the higher the car speed, the higher the pitch. If the car is driving away from you, the pitch will be lower. This is because the motion of the car is causing the sound waves to compress (driving toward you) or stretch (driving away from you), increasing or decreasing the frequency and raising or lowering the pitch.
How does the pitch of sound vary with frequency?
pitch corresponds directly with frequency, so as frequency increases, so does pitch.
Why Vibrate and pitch are connected because why?
the more the vibration, the lower the pitch.
What is pitch period?
The pitch period of a signal is the fundamental period of the signal, or in other words, the time interval on which the signal repeats itself. The pitch frequency is the inverse of the pitch period, which is the fundamental frequency of the signal.

For a stationary observer when the source of a sound is moving its?
When the source of a sound moves, the frequency noted by the observer will change. This is an example of Doppler's law. answer: its pitch appears to change.
What is a propeller pitch?
A screw's pitch is the amount it moves forward per turn. An airscrew (propellor) pitch is the same concept.
How the slide of a trombone changes the pitch of sound?
The pitch is changed on a Trombone by moving the slide or changing your ombisture.
How do you change a pitch of tambour?
By changing the frquency recipe of the soudn
How is the pitch changed on a trombone?
The pitch is changed on a trombone by moving the slide or changing your ombisture.
How do you get different pitches?
By changing the frequency of the vibration. High frequency = high pitch. Low frequency = low pitch.
What happens when the pitch of a sound seems to changeas the sound source moves toward an observer?
In that situation, what happens is that the pitch of sound seems to change as the sound source moves radially with respect to the observer. When the source approaches the observer, the pitch rises, whereas if the source should recede, then the pitch would fall.
How do you change pitch of a song without changing speed?
You can transpose it. Not sure, but there may be devices that can do this. You can change the pitch by using audacity. selecting the audio and then "change pitch."
If A fire truck siren sounds higher in pitch as it approaches and and lower in pitch as it moves away. What is the name of the phenomenon?
Doppler effect.
1 What does the trombone have that no other instrument has?
A movable slide as its method of changing pitch.
