AP PSYCHOLOGY

Detailed explanation-1: -pitch, in speech, the relative highness or lowness of a tone as perceived by the ear, which depends on the number of vibrations per second produced by the vocal cords. Pitch is the main acoustic correlate of tone and intonation (qq. v.). Related Topics: tone. wave.

Detailed explanation-2: -Pitch = a tone’s experienced highness or lowness; depends on frequency.

Detailed explanation-3: -In music, a sound that has a definite pitch is called a tone. It has a specific frequency, such as 440 cycles per second. The vibrations of a tone are regular and reach the ear at equal time intervals.

Detailed explanation-4: -The frequency theory of hearing proposes that whatever the pitch of a sound wave, nerve impulses of a corresponding frequency will be sent to the auditory nerve. For example, a tone measuring 600 hertz will be transduced into 600 nerve impulses a second.

Detailed explanation-5: -Sounds are higher or lower in pitch according to the frequency of vibration of the sound waves producing them. A high frequency (e.g., 880 hertz [Hz; cycles per second]) is perceived as a high pitch and a low frequency (e.g., 55 Hz) as a low pitch.
