There are a variety of hearing loss types and treatments. While the term “hearing loss” is often used in a general way to describe a reduced ability to hear or understand sounds and speech, it can be separated into three distinct categories.
Bilateral means hearing loss in both ears, whereas unilateral means hearing loss in one ear. In general , most people have one ear that hears better than the other. If hearing loss is present in both ears and seems to be of the same severity, this is referred to as symmetrical bilateral hearing loss. If hearing loss is present in both ears but at varying severity, this is called asymmetrical bilateral hearing loss. Bilateral and unilateral hearing loss can bother cuase by the same things, such as exposure to loud noise or ototoxic medications.
Low frequency hearing loss impacts the deeper pitches, typically 2,000 Hz and below. People can often understand speech fairly well with a low frequency hearing loss. People with high frequency hearing loss, on the other hand, have trouble hearing sounds in the 2,000 to 8,000 Hz range. This type of hearing loss means it's more difficult to understand speech, particularly the voices of women children.
