what is pitch in sound

Depending on the object and how it is made to produce the sound, you will get soft, low, or loud sound. However, as the car is traveling towards you the speed of the car is causing the sound waves to hit your ear faster or at a higher frequency than the car is making them. Higher the frequency, higher the pitch. Pitch, in music, position of a single sound in the complete range of sound. The amount of energy of a sound which spans a given radius is its intensity. The sound pitch will be higher as the car is coming towards you and then lower as the car moves away. Pitch is a perceptual property of sounds that allows their ordering on a frequency-related scale, or more commonly, pitch is the quality that makes it possible to judge sounds as "higher" and "lower" in the sense associated with musical melodies. Sounds are higher or lower in pitch according to the frequency of vibration of the sound waves producing them.

A sound might also seem high-pitched, like a squeak, or low pitched, like a rumble. Tone vs Pitch. Pitch relates to how high or low the sound is, which in turn depends on the frequency of the vibration Pitch is nothing to do with 'speed of speaking' as you suggest above. Pitch can be determined only in sounds that have a frequency that is clear and stable enough to distinguish from noise. The pitch of a sound is determined by its frequency, which is how many waves pass by each second. Pitch can be taken as the measure of sound frequency expressed in terms of Hertz. Sounds that have a high volume will have a high amplitude, and sounds that have a high pitch will have a high frequency. Its frequency is the same. However, the variations in sound are actually a result of tone, pitch and intensity. All kinds of sound produces some waves that are measured with respect to the frequency it carries. It is to do with the number of waves that are 'packed' into the sound - the more waves or cycles per second, the higher the frequency and therefore the higher the pitch. There are various sounds created by different objects. The sound the car is producing is not changing. A high frequency (e.g., 880 hertz) is perceived as a high pitch and a low frequency (e.g., 55 hertz) as a low pitch.
