IPA: /ɪnˈɔːdɪbɪlɪti/
KK: /ɪnˈɔːdɪbɪlɪti/
The quality of being unable to be heard or perceived by the ear.
The inaudibility of the sound made it difficult to detect the source.
Inaudibility → It is formed from "in-" (meaning not) and "audibilis" (from Latin, meaning able to be heard) and the suffix "-ity" (meaning the state or condition of). The word "inaudibility" refers to the state of not being able to be heard.
Think of 'not' ('in-') being able to be 'heard' ('audibilis') — that's why inaudibility means the condition of not being heard.
