Hearing Loss in Everyday Life

Hearing loss can range from mild to profound. This graph shows which sounds can or cannot be heard depending on the degree of hearing loss. For example, someone with a severe hearing loss can hear an airplane or a motorbike close-by (very loud, hence lower end of the graph). However, they will not be able to hear normal-level speech or birdsong. A bird’s tweet is a high-pitched tone, therefore it’s on the right of the graph; low-pitched tones are on the left.
