I can only echo what the others have said.
Typically with a new hearing aid, the volume is set low to start and during the adjustment period slowly increased to match your prescription. Have you tried using the volume control button on the aid to reduce the volume when you are in the car?
When I picked up my new hearing aids Nov 1, 2019, I remember the drive home being crazy with the tire noise so loud I could barely concentrate. My first adjustment was for 2 weeks later. I started making notes, which I highly recommend. Here are some examples of things to consider. Things like:
- in the car I have to reduce volume 3 beeps due to tire noise
- listening to the TV I have to increase volume 1 beep (or set the volume on the TV louder than acceptable)
- walking outdoors I can’t hear birds (high pitch sounds)
- I can hear my hair on my ears (for someone with shoulder length long hair, as an example)
- Sitting at the dining table I can hear the person on my right, not on my left, I have to turn towards the person
- Sitting at the table I can’t hear the person across from me; note it helps to specify if voice issues are male or female, that is high or low tones
This is all part of the process. Mechanically setting the hearing aid to match your prescription is only the first step in the process. Armed with all your situational info, you are set up to get the maximum benefit from your first appointment for adjustments. The audiologist will be able to look at the list and spot similarities. High tones with lots of background noise are lost, for example. And then the audi can make the adjustments to fine tune the hearing aid for you. The 2d appointment should go the same way, but you should have a much shorter list of concerns that need to be addressed. Usually the later appointments are when programs are set. Things like, when you are in a meeting room with 12 people, use program 1; when you are in the restaurant with a lot of ambient noise use program 2 to hear the female voices at your table.
Adjustments are when things get set based not only on your specific hearing, but also your specific lifestyle. I am retired so having meetings is a non-issue, but you may be in a work setting with meetings twice a day. I may attend a book club meeting at the library in a large room with many echo effects, but you may never be in such a situation. This is why your notes, as detailed as possible, will help improve things more rapidly at each adjustment appointment.
Sorry so many of my examples are from B.C. days. (Before Covid). In time I’ll get a new set of examples.
