Many people believe their unaided hearing gets worse after using a hearing aid. However, what actually happens is adaptation to hearing aids. You get used to the sounds offered by the hearing device.
Hearing the sounds’ breadth around you becomes the “new normal.” This is why, when you take off the hearing aid, your brain notes a stark contrast between the presence and absence of sound.
The unaided world of hearing loss seems quiet and dull as you get habitual of the input of the environment. Properly programmed hearing devices can never harm your auditory since, although it seems that raising sound level through hearing aids may be harmful.
Hearing devices are not, by any means, hearing protection. However, they have limits set on them for both comfort and safety purposes.
The hearing sense is a bit complicated and capable of learning how to sense new input. Your ears and brain adapt to this new normal as you start wearing a hearing aid more.
