Audible sound

Professional Definition
> Audible sound – a sound that evokes auditory sensation.

From a technical point of view, it is an acoustic wave whose frequency lies within the audible range (traditionally accepted as 20 Hz – 20,000 Hz).

## Acoustics in Simple Words
Audible sound is only that radio broadcast to which our biological receiver – the ear – is tuned. A dog whistle generates a physical wave, but for a human, it is not "audible sound".

## Summary
Audible sound is a subjective physical category, defined by the capabilities of the human ear.
