Do elderly individuals find themselves arguing with family members due to hearing loss?
When watching TV, do they turn up the volume so high that everyone has to speak loudly?
Do they feel frustrated at senior universities or community colleges because they can’t hear clearly?
Even worse, does their hearing loss lead to a fear of communication, causing them to isolate themselves, potentially inviting dementia?
