A pure tone is specified in which unit of measurement?

A pure tone is defined by its frequency, which is measured in Hertz (Hz) or cycles per second. This measurement describes how many times the sound wave completes a cycle in one second, providing essential information about the pitch of the sound. When discussing pure tones, we are referring to sounds that consist of a single frequency without any additional harmonics or overtones, making the measurement of frequency particularly relevant.

While decibels measure the intensity or loudness of a sound, acoustics refers to the study of sound and its properties, and sound pressure level quantifies sound intensity relative to a reference pressure. These concepts are important in the field of audiology and hearing aid technology but do not define the pure tone itself, which is fundamentally characterized by its frequency in Hertz.
