Thought I would ask. With my hearing aids, all of my dulcimores sound from bad to terrible. They are pretty pricey hearing aids, not like at Wally World. My audiologist added a "music" program. It must have been programmed for hard rock. Sure did not help. The audiologist is from the Appalachian Mountains and is familiar with the sweet voice of the dulcimore. She did say she is not surprised that the hearing aids do not "hear" the sounds of the dulcimore correctly.
I usually take them out or turn them off when I play.
Thought I'd ask if anyone else that wears hearing aids has noticed anything similar.
