Can you or your child hear sounds within the speech banana?
Contained within the speech banana are letters and letter combinations for these sounds.
To understand the speech banana, let’s first look at the audiogram.
talk-ds.org
The audiogram is used to graph hearing sensitivity.
Frequencies, also called pitch, are measured in Hertz (Hz).
Moving from top to bottom on the audiogram measures loudness in decibels (dB).
The further down on the graph, the louder the sound needs to be for be heard.
Also within the speech banana are the letter combinations /th/, /ch/, /sh/, and /ng/.
Those letter combinations can be difficult for deaf and hard-of-hearing people to hear and understand.
A count the dots audiogram has 100 dots, each representing 1% speech understanding.
In areas more important to speech understanding, the dots are closer together.
In areas less important, the dots are spread out more.
You will notice these dots are in the speech banana range.
