The 'Speech Banana' and the Sounds of Human Speech

The "Speech Banana" is a very useful visual tool for describing where the sounds used in everyday human speech occur on an audiogram. Parts of speech that are commonly used are known as "phonemes" and include "ng", "th", or "s" as well as many more. When mapped out on a graph, these phonemes form an almost banana-like shape, which is where the term "Speech Banana" comes from.

It is very common for seniors to lose their ability to clearly hear high frequency (4000 Hz and up) sounds.

High frequency hearing loss

Although hearing loss varies by degree and type, high-frequency (or high-pitch) hearing loss is one of the most common configurations of hearing loss. Hearing professionals define high-frequency hearing loss as hearing loss that occurs between 2000 Hertz (Hz) – 8000 Hertz. Decreased hearing acuity in the high-frequency range is often the first sign of hearing loss.

Individuals with high-frequency hearing loss have difficulty understanding speech in noise, and the voices of women and children, which are higher in pitch. Individuals with high-frequency hearing loss may also have difficulty hearing birds or the doorbell. Talking to family and friends over the telephone is also more challenging with high-frequency hearing loss.
