Getting used to new sounds
The human ear is a truly remarkable organ for picking up sound. But it is the brain that translates all the sound information into what we perceive as hearing. Therefore it is not just the ears, but also the brain that needs time to become accustomed to distinguishing new sounds.
The sound of your own voice
The sound of your own voice will, like many other sounds, appear unnatural when you first start wearing a hearing aid. One reason for this is to be found in the hearing loss itself, another in the hearing aid or earmould filling up space in the ear canal. All in all, the sound of your own voice will sound different, as a result of being processed by the hearing aid.
Chewing and swallowing sounds appear too loud
Many hearing aid users are surprised at how loud sounds from chewing and swallowing appear to them. The loud appearance of these sounds is due to the ear canal being closed off by the hearing aid or earmould. Another possible reason for this is that the brain, because of the hearing loss, has forgotten how chewing and swallowing sound. If the problems are caused by the ear mould or the hearing aid, the hearing care professional might be able to adjust these and thereby reduce the volume of these sounds.
