There is a web site called AMPHL ,it stands for assoc,of med.professionals with hearing loss. This coming week they are having their first annual get together in NJ. One of the main features and discussions will be about the best stethoscopes for different types of hearing loss. There are med.profs.from all levels that are involved in this. I too have some hearing loss and my biggest issue is my stethoscope. It has been a gradual hearing loss,and can be frustrating at times. Hope this helps.
