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.
What does this mean how high or low a sound seems?
Pitch
Why does the pitch of a sound change as the source of the sound that moves past you?
Decreasing velocity, and distance.
What property describes how HIGH or LOW a sound seems to a person?
pitch
What is the type of pitch produced when a loud objects has passed you?
When a loud object such as a train passes you, there is what is officially known as the Doppler Effect, by which the sound has a higher pitch as the object approaches, and a lower pitch as it passes. The speed of the object, whether approaching or receding, affects the wavelength of the sound.
What seems to be relationship between the frquency of a sound wave and the pitch of the sound you hear?
There is a direct relationship. The higher the frequency, the higher the perceived pitch.
When an automobile moves toward a listener the sound of its horn seems relatively?
high pitched
What happens to the pitch when the sound source moves away from you?
The pitch lowers as the wavelength of the sound increases. It's called the Doppler effect
How does perceived pitch change as a sound passes a listener?
Herr Doppler noted that the pitch is higher as the object approaches and lower as the object departs.
What lets you know that the source of a sound is moving toward or away from you?
When a sound-source moves toward you, its pitch gets higher and the sound gets louder. When it moves away, the pitch lowers and it gets quieter. The frequency change is called the Doppler shift.
When a sound wave moves past a point in air what happens to the density of air at this point?
The density of air increases and then decreases as the sound wave passes.
What is a apparent change in pitch of a sound caused by the motion of the object making the sound?
This is an example of the Doppler effect. Sound is composed of waves. A particular vibration produces a sound wave with a particular wavelength. When the sound source moves towards a listener the waves are "bunched up". That results in a shorter observed wavelength and thus a higher frequency. When the sound source moves away the opposite happens. The frequency of the sound waves decreases.
