How is pitch defined in auditory terms?

Pitch in auditory terms is defined as the psychoacoustic perception of frequency. This means that pitch relates to how humans perceive different frequencies of sound. While frequency itself is a measurable physical attribute defined in Hertz (Hz), pitch is more about the subjective experience and interpretation of those frequencies by the human ear and brain.

For example, a sound with a higher frequency is typically perceived as having a higher pitch, whereas a sound with a lower frequency is perceived as having a lower pitch. This perception can be influenced by various factors, including the listener's hearing ability and context in which the sound is heard. Understanding pitch is crucial for hearing instrument specialists, as they need to help clients find solutions that accommodate their perception of sound to improve their communication and experience with hearing devices.

The other options relate to sound in different ways: the physical measurement of sound pertains to characteristics like amplitude and wavelength, volume relates to the perceived loudness or intensity of sound, and the location of the sound source involves spatial perception rather than the frequency or pitch itself.
