Hearing defects may arise out of a number of reasons but the most common reason is genetic. Hearing defects may also arise as a result of improper lifestyle, being subjected to loud sounds like honking of a car, living very close to busy streets or factories, pollution, accidents, disease, and a number of other hitherto unknown or undiscovered factors. Another reason why hearing defects could arise is due to the excessive use of drugs or prescription pills, or in the event of shouting a lot.
Hearing aids are a really useful device in the present day. Hearing aids basically serve the single most important function of picking up sounds of low intensity and low frequency and amplifying them to create a resonance like situation so that the sound can be heard very easily by a person who has a hidden hearing defect or impairment.
Thus hearing aids a very important gadget, and possibly one of the most important devices used in the present day. A defect of hearing aids can occur if the device is capable of picking up sounds of very low intensity like the breeze or breathing. In such a case, a constant whirring or buzzing sound may be heard and this could result in headaches, and other physiological problems. A solution to this problem may be obtained by only turning on the device for the purpose of communication. But often this is not the case, for instance if a person is crossing a busy street the device needs to be switched on continuously.
In the event of complete hearing loss it becomes very difficult to make a person hear and even hearing aid do not serve much purpose, but in the event of partial hearing loss it hearing can be restored to a certain extent by using hearing aids.
