Overview of Hearing Loss
Definition of hearing loss
Hearing loss refers to a decrease in the ability to hear sounds. It can range from mild to profound, and can affect one or both ears. The loss of hearing can be either temporary or permanent, and it can result in difficulties understanding speech, communicating with others, and participating in daily activities.
Types of hearing loss
There are different types of hearing loss, which are categorized based on the specific part of the auditory system that is affected. Sensorineural hearing loss occurs when there is damage to the hair cells in the inner ear or to the nerve pathways that transmit sound signals to the brain. Conductive hearing loss, on the other hand, is caused by a blockage or damage to the outer or middle ear, preventing sound from reaching the inner ear. Mixed hearing loss involves a combination of both sensorineural and conductive hearing loss.
Causes of hearing loss
Hearing loss can be caused by a variety of factors. Some people are born with hearing loss, which is known as congenital hearing loss. It can occur due to genetic factors, exposure to certain infections or diseases during pregnancy, or complications during childbirth. Acquired hearing loss, on the other hand, can develop at any age as a result of various causes such as exposure to loud noises, aging, certain medications, infections, or illnesses. Other factors such as head trauma, ear infections, and excessive earwax buildup can also contribute to hearing loss.
