Audiogram: hearing loss

How Hearing Loss Affects Speech Understanding

This is an audiogram that depicts a hypothetical hearing loss. The red points indicate the softest sounds that can be heard at various frequencies or pitches. The shaded region represents that range of sounds that cannot be heard. Everything under the red line is audible, but may be perceived as softer than normal. Notice how certain sounds are filtered out by this hearing loss. To a person living with this loss, the words, “that”, “sat”, and “fat” will all sound like “at”. It is easy to see how hearing loss makes it seem like others are mumbling!
