Profound - At this point, with a degree of hearing loss over 85 db., cochlear implants may be the only option.
Hearing begins when the outer ear directs or channels sound waves through the ear canal to the eardrum. The inner ear converts the sound waves to nerve impulses and these are transferred via the haircells in the cochlea to the nerve and then to the brain. Typical problems which occur in the outer ear are waxplugs, foreign objects in the canal and infections of the earcanal.
The most common problems which occur in the middle ear are infections, fluid behind the eardrum, perforated eardrums and calcification of the middle ear bones (otosclerosis). The most common problem is caused by the natural aging process.Other causes include prolonged exposure to loud sounds, exposure to certain medications and skull fractures. There is a large spectrum of hearing loss between the ability to hear "well" and hear "nothing".
Frequent exposure to loud or moderately loud noise over a long period of time can damage the fine hair cells of the inner ear.
Both the amount of noise and the length of time you are exposed to the noise determine its potential to damage your hearing.
Although noise-induced hearing loss is one of the most common occupational illnesses, it is often ignored because there are no visible effects. People often assume that if the symptoms go away, their hearing has recovered back to normal. Non-occupational noises are also regularly encountered during recreational activities and are a source of premature hearing reduction. Hunting requires one to have the ability to hear very soft sounds, while still protecting the ear from the peak noise levels of a shot gun blast. Professional musicians work in a high decibel environment in which hearing loss, tinnitus, hyper-sensitivity to sound and sound distortion can result. Conductive hearing loss is caused by any condition that blocks or impedes the conveyance of sound through the outer or middle ear. The single most important sign of hearing loss in children is the failure to develop language. Hearing tests can be done in children of any age using objective and subjective audiologic test technologies. People with hearing loss seem to delay a decision to get hearing help because they are unaware of the fact that receiving early treatment for hearing loss has the potential to literally transform their lives. If you are one of those people with even a mild hearing loss, consider all the benefits of hearing aids described above.

A person in close proximity will not have much difficulty comprehending what is being said to them, but may have trouble at a greater distance.
In most instances, yes, but if hearing difficulty is profound a cochlear implant is the recommended choice. The sound waves cause the eardrum to vibrate ant this movement is then transferred to thehammer from where it it is transferred to the anvil and in turn the stirrup from where it is transferred to the inner ear. Any damage to the minute inner ear hair cells will afeect the transfer of sounds to the hearing nerve.
In turn, a person with a hearing loss can also not describe to us what it sounds like not to hear certain sounds.
Next to age, it is the most common cause of permanent hearing loss and can therefore usually not be corrected surgically or medically. Cells and nerves in the inner ear are destroyed by continuous or repeated exposure to loud sounds. A noise-induced hearing loss usually develops over a long period of time, and is very rarely associated with any pain. This results in a progressive loss of communication, socialization, and responsiveness to the environment. Traditional earplugs will not work for the professional musician, as they reduce sound by muffling low-to-mid-range frequencies.
It is generally thought that loud noises in excess of 90 decibels are harmful to hearing over prolonged exposure.
Loud, sudden noises (gunfire, industrial noises, woodworking, motorcycles, loud music, motorized lawn equipment, noisy hobbies and other noises louder than 90 db) are more damaging to hearing than earplugs can significantly reduce loud noises and prevent hearing damage and loss. If children have severe or profound hearing loss, it is obvious because they do not respond to sound.
Research demonstrated that hearing aids are associated with impressive improvements in the social, emotional, psychological, and physical well-being of people with hearing loss. An audiometer is used to determine the degree of hearing loss, and results are measured in decibels.
The most common degree of hearing loss which is seen in practice is mild to moderate or moderately-severe.
The symptoms are usually feelings of pressure or fullness in the ears, speech sounds muffled, and a ringing sound in the ears, usually noticed when in a quiet place.


Even if no more symptoms occur, some of the cells in the inner ear may have been destroyed or damaged by the exposure to noise.
Not only can they choose from custom or over-the-counter ear plugs or ear muffs, they can also choose protection devices that provide amplification while reducing the sounds of gunfire down to a safe level.
Special musicians ear moulds are available that can protect the musician's ears from loud sounds without distortingwhat they hear.
Hearing protectors not properly fitted to the wearer's ears do not effectively prevent damaging noises from penetrating the ear canal. Sometimes it is difficult to detect mild forms of hearing loss, including a hearing loss only in one ear. It is an easy way to check whether the entire spectrum of speech is still audible and how a person’s hearing changes with time.
You will develop a permanent hearing loss if the noise exposure is repeated and more cells are destroyed.
It, too, reduces the intensity of the sound, but it might also result in a lack of clarity even when sounds, particularly speech, are loud enough.
Even a mild hearing loss can have a negative impact on communication development and school performance.
There is a process of teaching and rehab, as well as on going tuning visits with the audiologist 2-3 times per year. Benjamin Franklin got it right when he said "an ounce of prevention is worth a pound of cure." Just as you would take preventative measures to protect yourself from heart disease or diabetes, it pays to protect yourself from hearing loss.
Sound waves enter via the outer ear into the ear canal where the sound vibrates on the eardrum.
The vibrations then travel to the air filled middle ear where tiny bones send sound to the hair cells located in the fluid filled inner ear.
The hair cells send electrical impulses to the hearing nerve, which relays them to the brain where the pulses are read, thus producing the sounds that we hear. Depending on the type of hearing loss and the extent of damage, this hearing mechanism is stopped along the way, resulting in hearing loss.
If you feel your hearing has suffered a deficit, it is important to consult with your heath care professional to diagnosis and treatment.
