audibility

This term describes the physical or technical capacity of a sound to be perceived. It is often used in acoustic engineering or public speaking contexts to describe whether a signal is strong enough to overcome background noise or whether it falls within the biological range of human hearing.

As an uncountable noun, it refers to a quality or a state rather than a discrete object. It does not have a plural form and cannot be counted using numbers; instead, it is modified by adjectives such as high, low, or poor to indicate the degree of clarity or reach.
