My husband is very hard of hearing, has hearing aids but still has much difficulty and gets frustrated. We’ve developed a limited sign language, done with pointing, finger motions, facial expressions, lots of smiles and the “I love you” sign. For talking, I have the house phone speaker function turned on and I call him from my cell phone. Feels silly to be in the Lazy-Boy and he’s 6 feet away at the computer desk, but it really works for verbal communication. Maybe amplification on both sides would help with the dystonia.
