People who suffer from hearing problems have to face many problems in their life.This problem is quite common in old age but some people suffer from hearing problems even in their youth.We come across many people during out routine life with whom we have to converse on various important matters and it is possible to understand the words spoken by others only if we are able to hear it properly.With the advancement of technology, such devices have been created by the scientists, which can help people to improve their sense of hearing.These devices are known as hearing aids.People who are hard of hearing can use these aids and hence hear better.Hearing aid is a device which runs on battery supported by the electricity.These devices are put inside the ear or behind it.Hearing aids are designed in such a way that these help in increasing the sounds for the users and help them hear well.Different hearing aids function in different ways to make sense of hearing better.
Transformation of sound waves- The sound waves are converted into electrical currents with the help of Analogue hearing aids which are then increased and are made to run into the ear canal.On the other hand, a small chip is used to transform sound waves into computer language with the help of digital aids.The sounds thus produced are decoded and converted into audio patterns which can be modified to fulfil the different hearing requirements of different persons.
Digital Technology- There are hearing improvement devices which are available as distinct units that are cut back at the back of the ear with a tube that goes straightway into the ear to get linked with a small earpiece.Digital technology is used in these devices to make sound waves perceptible to the hearing impaired person.
Bone Conduction process- Some people are hard of hearing due to loss of conductive hearing.In such a situation, sound waves are not able to travel via the inner chambers of the ear.Such a problem is handled by using bone conduction devices through which sound waves are made to re-travel into the skull from the ear canal through a headband fitting.The sound waves are then transferred straightway into the ear through vibration and hence improve hearing process.
Stimulation of Auditory nerve- People who suffer from hearing problems need some sort of stimulation to their hearing or auditory nerve.It is because they can’t hear or recognise some sounds.The main aim of any type of hearing device is to stimulate the auditory nerve so that it may not degenerate over passage of time due to non-receipt of sounds by it.The activation of auditory nerve aided by constant use of hearing devices helps in improvement of hearing process.
As we have noted, there are various processes which help a person who is suffering from hearing impairment to improve his hearing capacity.The only important thing is to use any type of technology as per your individual needs and according to your comfort level of using these devices.
