How is amplitude measured?

Amplitude is measured in decibels (dB), which is a logarithmic unit that quantifies sound intensity and helps in comparing sound levels. In the context of audiology and hearing testing, the amplitude reflects the power or strength of a sound signal. A higher amplitude indicates a louder sound, while a lower amplitude denotes a quieter sound.

Using decibels provides a standardized way to communicate and understand sound intensity levels. This measurement is crucial in hearing assessments, as it allows for the comparison of different sounds and their potential impact on hearing.

The other units listed pertain to different measurements. Hertz (Hz) measures frequency, indicating the number of cycles per second of a sound wave. Frames per second (fps) relates to visual content, particularly in video frame rates. Meters (m) measure distance, not sound intensity. Each of these measurements serves a specific purpose in their respective fields but does not pertain to the assessment of sound amplitude like decibels do.
