How Is Tinnitus Connected To Hearing Loss?

tinnitus and hearing loss

In the recent years, extensive medical research has found that there is some connection between hearing loss and tinnitus. For some affected people, it can be partial, affecting only a narrow band of sound frequency as a consequence of minor injury to the inner ear. This may or may not impact your hearing ability, however, anything of this nature should be given immediate attention, before it turns into something dangerous.

Such a hearing loss is probably immeasurable by conventional tests, since it is hard to figure out a defect like this. There can be many reasons behind sudden loss of hearing, with the typical sign being difficulty to hear, because of background noise. Whatever be the cause, such a disorder needs serious attention at the earliest.

Absence Of Audiological Input

In the recent years, several medical research have indicated that tinnitus is caused by reduced or absent nerve activity in the nerves connecting the central nervous system in the brain to the damaged part of the inner ear. As the signals approach to the hearing center of the brain, it can lead to increased nerve activity, which in turn reverts back to the hearing center. Although the ear does not pick up any sound from the surrounding, still some sound is heard. This condition is called tinnitus.

Noise-induced hearing loss can be caused by acoustic overexposure, which can damage both the hair cells of the inner ear and the nerves sending the signals to the brain from the inner ear. Other things such as otoxic drugs can also damage the nerves and the hair cells.

Wrong Signals To The Brain

According to a medical research, the hearing nerves between the brain and the inner ear send spontaneous signals to the central nervous system due to the reduced or absent audiological input. It can be interpreted as sound, and is known as tinnitus. In a majority of cases tested on animals suffering from a hearing loss, most of them had tinnitus. You are more likely to hear phantom sounds, if you are suffering from reduced audiological input.

Other studies have also suggested that treatment of hearing defect and thereby augmenting the audiological input, through operations or hearing aids, can minimize the effect of tinnitus. The reason behind this is the fact that such an input can hide the tinnitus wholly or partially. Another reason could be reduction in the spontaneous signals in the nerves. It’s not necessary to be suffering from tinnitus in case of hear loss, but anyone with tinnitus may experience some hearing loss.
With all this information, you can benefit even more by seeing a professional, most preferably an otolaryngologist, who is also trained in tinnitus management. Although it is true that there is no complete cure for tinnitus, there are a few things that can be done to alleviate or manage the impact it has on your daily life. Some people have also reported complete ending of tinnitus after sound therapy or counseling and use of hearing aids.
