If you have hearing loss on both sides, one hearing aid is not enough. With two hearing aids you ensure that directional hearing remains good and that you achieve maximum speech understanding in more difficult listening situations.
As hearing aids become more sophisticated, a behind-the-ear hearing aid not only amplifies the sounds from behind. Because a behind-the-ear hearing aid uses multiple microphones, the sounds from the front come through better than the sounds from behind.
The hearing aid batteries use a constant current, if the hearing aid gives a signal that the battery is almost empty, there is only a chance that the gain will decrease.
Groups fall under the difficult listening situations, which makes it important to have a more advanced hearing aid. If you opt for a less advanced hearing aid, you may still have trouble following conversations in groups.
Advanced hearing aids ensure that you do not have to make any adjustments to the hearing aid yourself. The more advanced the hearing aid, the less you have to control.
Behind the ear hearing aids are getting smaller / narrower, so it is no problem if you wear glasses. The temple and the hearing aid can be worn side by side. Another option is an in-ear hearing aid, so that nothing is behind the ear.
You are entitled to reimbursement once every five years from the health insurer, but that does not mean that you have to do it for five years. Manufacturers are coming up with improved techniques faster and faster, so that you experience fewer and fewer problems with your hearing loss. So it may be worth replacing your hearing aids sooner.
