Additionally, millions of Americans have tinnitus (ringing or buzzing in the ears), auditory processing problems (trouble focusing on and/or misunderstanding what is heard), frequent ear infections, and balance problems (dizziness or unsteadiness) that can occur with or without hearing loss and at any age.
