Personaly, I wouldn’t go that route but would rather use some good earplugs, foam or otherwise. There are good plugs on the market. I’ve worked in high-noise areas like the diesel generator rooms at nuclear plants and flying as a pilot, so I’ve had chances to use good ones.
The reason I would opt for plugs: there’s a good chance that I would become so used to sleeping with the aids in that I would wander into the shower with them on in the morning. Beyond that, I don’t like the thought of depriving the little speakers on the end of the stalk on each aid some time to dry out after having been in a humid ear for a very long time (collectively) over the course of 24 hours.
And, you are effectively doubling the number of charging cycles on the batteries. On top of all that, I would think the ears might get a bit ticked off at us if subjected to near constant intrusion from the hearing aid,
That advice and a well-funded Starbucks card will get you coffee and not much else. But that’s my take on your issue. And all of this presupposes its bad form to stifle the individual who is snoring.
Cheers.
