Technically speaking, your ability to hear will not be worse just because you don’t wear hearing aids. Anyway, the gradual progression of hearing loss will occur whether you are wearing hearing aids or not. But our brain’s ability to understand language, like our bodies, needs to be exercised to stay healthy.
If we miss some sounds over time, our brain is less stimulated and therefore speech recognition will be poor.
Simply put, wearing hearing aids can compensate for your loss of hearing and ensure that your brain and nerves are stimulated. If you have a hearing loss and don’t get help, your speech discrimination will be affected in the long term.
