Environment produces lots of sounds. Be it the cool music from an mp3 player, the noisy of an angry crowd or even conversation between people. Man uses these sounds to analyze the environment and make decisions depending on them. With loss of hearing ability, the life of an individual can be greatly changed. To help in such situations, hearing aids have been developed.
The most basic benefit of these devices is to improve the ability of an individual to hear. They achieve this by amplifying the surrounding sounds to levels much higher so that an individual can hear them. This enables the individual to hold conversation, cross streets safely and also listen to music.
A hearing aid is much affordable. Compared to surgery involved in cochlear implant, these devices are much cheaper and are hence accessible to the majority in the society. Cochlear implant is for those people who have enough money.
The device warns the owner of dying battery. This is just the same way as a cell phone warns the owner when the battery is low and needs recharging. The device is made to do the warning so early so that the patient can get time to charge them without they completely run out of battery.
Unlike cochlear implants, having a phone conversation with the device is easy. Easy phone conversation means an individual does not have to depend on relatives for communication through phone. They can also talk to friends and family members without making it public. One cannot get this opportunity with the implants.
Although hearing aids have several benefits, they also have some disadvantages. When using them in noisy places, it is very difficult to concentrate on a conversation. Also repetitive use of the device leads to worsening of a hearing problem instead of enhancing it. This increases ones problems with time.
