As any layman would know, hearing and understanding are two different ball games. Hearing is being able to pick up sound signals through the auditory senses while understanding is deriving meaning and comprehension out of those sound signals. These two functions are carried out by different organs of the body. The auditory part is usually handled by the ears and the auditory nerves. Understanding is essentially a function of the brain.
When the sound signals reach the brain through the auditory channel, the brain interprets these sound signals into meaningful words. That is why you are able to listen a word you don’t know the meaning of, but you cannot understand it. This is so because the brain has no prior knowledge of the word and does not associate the word with any meaning whatsoever.
Sometimes, for people who suffer from hearing loss, understanding some words becomes more difficult. ear loss is usually measured in frequencies. People are diagnosed with the problem when they cannot hear words within the range of a certain frequency of sound waves. With this loss of ability, the brain loses its own power of interpreting the signals. As a result, when a person cures the hearing problem with the help of ear aids, the problem of interpreting the sound signal continues to bother.
The brain in this stage receives the sound signals alright, but cannot make any sense of it. In other words, the purpose of using listening aids is dampened because you cannot figure out the words anyway, so hearing them does not improve your situation. What you need at this stage is auditory rehabilitation therapy.
The purpose of this rehab program is to familiarise your brain with those long-lost sound signals again, making it possible for you to understand those words again. The key goals of this program is to ensure that you have better comprehension of speech and are able to derive better understanding of the words that you have heard. Simply letting the hearing aids do their job will not be beneficial to you, especially if you are in the category of moderate to severe hearing loss.
If you are facing trouble with understanding words despite hearing them through your hearing devices, you should consult our team of audiologists at Bengal Speech. They will guide you toward an auditory rehab program to boost up your hearing comprehensibility.
