When I lost my hearing and started wearing a hearing aid, I also had many questions. I understood that I was clueless about many things I hadn't even thought about before. Having addressed a hearing aids staten island ny clinic, I found out everything I needed to know. Of course, I also worried about sleeping with my device on. From an audiologist, I found out that hearing aids aren't designed to be worn at night. They won't help you hear better when you are sleeping (e.g. you won't hear your alarm clock better). Thus, there is no sense in wearing a hearing aid at night.
