Sensorineural hearing loss can develop due to several factors such as age, noise, infections and diseases. This happens as the result of damage to the tiny hair cells of the inner ear. People, as they age, tend to lose these tiny hair cells, resulting in the gradual hearing loss.
This is the common form of hearing loss affecting 23% of the population who are older than 65 years. The disorder of the cochlear nerve or the cochlea is the source of this hearing loss. The general causes of this condition include advanced age in individuals, the onset of other disorders such as meniere’s disease, immune disorders, head trauma, severe noise exposure and rarely tumors. Meningitis is associated with the hearing loss in children particularly the cases that are affected by streptococcus pneumonia meningitis. People with this hearing loss may not regain their hearing, but the sensorineural hearing aids can assist these individuals, however, in some cases, surgical intervention has partly treated the condition.
Conductive hearing loss
This hearing loss develops with the inability of the ear to conduct the sound to the inner ear. Generally, this type of hearing loss is temporary which can be treated with the proper medical intervention. The signs of conductive hearing loss include hearing faint sounds and reduced sound level. One of the common causes of conductive hearing loss is ear wax. The other causes include infection of the ear, ruptured eardrum, the result of a very small ear and the presence of foreign objects in the ear canal. The conductive hearing loss of the middle ear occurs as the result of chronic infections that results in the build-up of fluids in the middle ear, diseases and tumors.
Hearing loss can actually be prevented in some of the cases. Medications that have side effects associated with hearing loss include ototoxic drugs such as certain antibiotics, chemotherapy drugs and high doses of aspirin. The side effect of these medications may include the tinnitus sound in the ears, pressure in the ears, vertigo and hearing loss in the healthy ear. Noise-induced hearing loss can be completely preventable by wearing noise protectors such as earmuffs and well fitting ear plugs. It is estimated that 15% of Americans between the age of 20-69 suffer from hearing loss as the result of loud noise which may be related to occupational or leisure activities. Individuals who are exposed to over 85 decibels of sound are at increased risk of developing hearing loss induced by the loud noise. In some of the occasions, the ears can actually indicate warning signs with exposure to very loud sound. The indicative signs include having to raise your voice when communicating with someone nearby, painful ears caused by the noise, a buzzing sound developing in the ears and not being able to hear well even when you move away from the noise.
