Mild hearing loss
Soft noises are not heard. Understanding speech is difficult in a loud environment.
Moderate hearing loss
Soft and moderately loud noises are not heard. Understanding speech becomes very difficult if background noise is present.
Severe hearing loss
Conversations have to be conducted loudly. Group conversations are possible only with a lot of effort.
Profound hearing loss
Some very loud noises are heard. Without a hearing aid, communication is no longer possible even with intense effort.
The sound of speech
Human speech consists of vowels and consonants at different loudness and frequency levels. They are recorded on the audiogram as a so-called “speech banana”. It is an easy way to check whether the entire spectrum of speech is still audible and how a person’s hearing changes with time.
