How is frequency measured?

Frequency is measured in hertz (Hz), which represents the number of cycles of a periodic wave that occur in one second. This unit is crucial in acoustics, as it helps quantify the pitch of sound; higher frequencies correspond to higher pitches, while lower frequencies indicate lower pitches.

Understanding frequency is essential for audiology and hearing technology, as it directly relates to the human ear's ability to perceive different sound levels and qualities. The concept of hertz connects directly to various applications in hearing assessments, enabling hearing technicians to evaluate and address hearing impairments effectively.

Decibels (dB) measure sound intensity or loudness, watts (W) relate to power, and pounds (lb) are a measure of weight, making them irrelevant for measuring frequency.
