Quais são os diferentes graus de perda auditiva?

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.
