What causes the change in pitch of an approaching train whistle?
sound is wavelengths, and wavelengths get compressed when coming to you (and stretched when going away). the closer the wavelengths, the higher the pitch!
What property of sound determines the pitch of a sound?
It is the frequency of a sound that determines its pitch. The higher the frequency, the higher the pitch.
Pitch describes the loudness of a sound?
Pitch describes the frequency of a sound.
When a source of sound moves toward a person what does pitch do?
As sound travels, the waves spread out and lose energy. Since the energy of a sound wave is proporitonal to it's total energy, losing energy causes the frequency to decrease. Pitch is human perception of frequenct, so the pitch drops as the waves propagate.
How is noise related with pitch?
Pitch refers to a sound with specific tones. The pitch of a sound is determined by the spaces between the sound waves. A sound is considered by noise by determining the level of loudness of the sound.
What causes a high sound compared with a low sound?
The difference in pitch.
What causes pitch to change?
Every sound vibrates with a particular fundamental frequency. When you change the wavelength of a sound, you change the pitch of a sound.
What causes a sound in front of a moving sound source to seem to have a higher pitch and frequency?
Doppler effect
What causes the change in pitch of an approaching train whistle?

What properties of sound determine the pitch of sound?
The pitch is determined by how high the sound is.
What property of sound determines the pitch of a sound?
It is the frequency of a sound that determines its pitch. The higher the frequency, the higher the pitch.
How does loosening a string change the sound of a guitar string?
It causes the string to vibrate more slowly, decreasing the pitch (frequency).
What causes a low or high pitch?
In general, a low pitch is created by sound waves vibrating and having to travel down a lengthy object, while a high pitch only has to travel down a shorter distance
Pitch describes the loudness of a sound?
Pitch describes the frequency of a sound.
What is a sound that has a definite pitch?
A sound that has a definite pitch is a note.
Is pitch used to find loud or soft sound?
pitch isn't used to find sound but pitch is if the sound is loud or soft. the pitch of music may vary.
How does tube length affect sound?
A longer tube causes the soundwave to have a longer wavelength, a lower frequency and hence have a lower pitch.
