- speak in a high-pitched voice
- use sign language
- ensure the room is well lit
- refrain from touching the client
Number 3 is correct.
Proper lighting allows the client to see your face, improving communication. In many types of hearing loss, the ability to hear higher-pitched tones is lost. Unless you know the client knows sign language, this communication form will frustrate the client. Gentle touching allows the client to know where you are located.
