What unit is commonly used to measure frequency?

Frequency refers to the number of cycles of a periodic wave that occur in one second. The standard unit for measuring frequency is Hertz (Hz), which is defined as one cycle per second. This unit is widely used in various fields, including acoustics, telecommunications, and electronics, to describe phenomena such as sound waves and radio signals.

In the context of hearing instruments, understanding frequency is crucial as it relates to how sound waves behave and how they are processed by hearing aids. Frequencies can have a direct impact on how well an individual can perceive different sounds, such as speech or music.

Other units listed, while important in their respective contexts, measure different physical properties. For example, Watts relate to power, Pascals measure pressure, and Decibels represent a logarithmic scale for intensity or sound level, not frequency itself. Therefore, Hertz is the appropriate unit to measure frequency.
