I went through a very similar experience with the VA (minus the motorcycle) just a few months ago. I got plenty of help in this thread: http://www.hearingaidforums.com/showthread.php?20300-New-VA-hearing-aid-user-seeking-advice I don’t know if it will help you, but there it is.
The VA will also provide you with any of the accessories you might need. I highly recommend the Phone Clip+. Among other things, it has one button on the front which will allow you to cycle through whatever programs the audiologist puts in for you. Another button will mute the microphones on the aids. If you don’t wear earplugs on the bike, you can at least use this button to effectively turn off the aids.
You will be going back to the VA audiologist for follow-up adjustments. They may not tell you that, but they’ll give you an appointment any time you call. Expect a two plus week delay in appointments. For one thing, initially they probably won’t program the aids to give you all the gain you’ll need. This gives you time to adjust to them. You will know when it’s time to ask for more. It may take two or three follow-ups before they get you up to full levels.
As Ken said, keep good notes so you don’t forget to tell the audi what you need and to point out any problems. I recommend you be especially picky about comfort. If your aids are uncomfortable, you probably won’t wear them as much as you should. I wear mine anytime I’m not asleep - 16 to 18 hours a day.
