A hearing loss changes the relative loudness of sound. Things that are soft to you may not be heard by your family member. Sounds that are comfortable to you may be soft for your family member. Loud or sudden noises, however, may be more uncomfortable or unsettling than for you. Let your family member know when their voice may be too loud or too soft.
Some rooms have better acoustics than others.
Empty rooms with hard walls may cause speech to echo. Your family member may not hear as well as usual when tired or ill. This is because it may be difficult to put as much effort into attempting to understand speech. Try to converse in well lit rooms. If glasses are needed, make sure they are used.
