what is the speech banana on a hearing test

A useful way to look at the audiogram is to superimpose a ‘speech banana’ on it. The speech banana is so called because of its shape. It represents the intensity and frequency of sounds of speech or ‘phonemes’ in language, which when placed on the audiogram, form a banana like shape.

In adults hearing loss within the speech banana can have serious implications on the person’s ability to follow what is being said to them (speech discrimination).
