What is Hearing Loss ?

Hearing loss is the inability to hear partially or totally in one or both ears. Generally, sound is indicated by 'frequency' and 'intensity'. In 'frequency', our ears can normally hear between 20 to 20,000 Hertz. When hearing threshold or the least hearing ability of a person is over 25 dB (decibel), then it can be termed as hearing loss or impairment. Hearing loss treatment involves diagnosis of the type and degree of hearing loss and based on the type and degree of hearing loss the treatment would be either medical or rehabilitative.

Types of Hearing Loss

Hearing loss can be mild, severe or profound, depending upon the type of hearing loss and the degree of hearing threshlod (the least hearing ability of a person). The type of hearing loss is identified by detecting which area or section of the ear the problem is originating from. The three main section of the ear are termed as the outer, middle and inner ear.

Conductive Hearing Loss

 

Hearing loss due to problems in outer or middle ear is termed as conductive hearing loss. Generally, such problems may be cured with proper medication or the use of hearing aids.

Sensorineural Hearing Loss

 

Sensorineural hearing loss is hearing problems arising out of inner ear or auditory nerve disorders. Though it is a permanent problem, hearing restoration is absolutely possible with the help of hearing aids or other hearing devices.

Sensorineural Hearing Loss

Mixed Hearing Loss

 

A combination of conductive and sensorineural hearing loss (problems in both outer/middle and inner ear) is termed as mixed hearing loss. Hearing aids or other hearing devices can help in hearing restoration for most of the patients suffering from this type of hearing loss.

Hearing Restoration Procedure

Hearing Loss Treatment depends on the type of hearing loss that an individual is suffering from. If the Hearing Loss is of conductive in nature and is temporary, usually the treatment of choice is medical i.e. medication or surgery. If the hearing loss is of sensorineural in origin the said hearing loss is permanent in nature or is irreversible. Hence, hearing loss treatment in this case would be either hearing aids or cochlear implant. For Mixed Hearing loss individuals the treatment involves medication or surgery to control the hearing loss of conductive origin followed by hearing restoration through hearing aids for the sensorineural component.
