Sensorineural Hearing Loss
Sensorineural hearing loss occurs from damage to an individual’s inner ear (cochlea) or neural areas of the auditory system. In some cases, the cause cannot be determined. It is generally irreversible and permanent. The most common type of hearing loss, sensorineural or SNHL, results in a loss of loudness as well as a lack of clarity. Those who are diagnosed with this type of hearing loss have to wear hearing aids or other devices to improve hearing. Sensorineural hearing impairment is becoming more common due to prolonged exposure to excessively loud noise from work environment or from listening to loud music. This type of hearing loss can be caused genetically and in such case, a person can lose their hearing ability due to head injuries. There are lots of reasons why this hearing loss happens. It can happen from birth or might occur early or late in life. Some reasons can also be smoking, diseases, and even taking certain medications.
The most common indicator of having it in both ears is; inability to understand speech clearly even when it is loud enough. A person would find it difficult to understand all types of high-pitched even the chirping of birds. Whereas, when it occurs in one ear, a person has trouble locating sounds or hearing background noise.
