Types and Causes of Peripheral Hearing Loss
... Inherited causes (family history of hearing loss alone), in-utero infections (eg, CMV), hearing loss as part of a syndrome (eg, Pendred’s), neurodegenerative disorders (eg, neurofibromatosis), need for post natal or later intensive care with effects on the cochlea and auditory nerve (eg, prematurity ...

Our Ears and How We Hear
... Use of a cotton bud or similar object to try and remove wax may cause injury and will only push most of the wax further into the ear canal. Consult a doctor if a blockage of wax occurs. Do not attempt to remove it yourself. Noise Prolonged exposure to loud noise can permanently damage hearing by cau ...

Earplug
An earplug is a device that is meant to be inserted in the ear canal to protect the user's ears from loud noises or the intrusion of water, foreign bodies, dust or excessive wind.
