The anatomical location cited where hair cells are destroyed by hazardous noise in Composer Uses Music to Elucidate Tinnitus is in error, e.g., “Both occasional exposure to very loud, sharp noise and steady, prolonged exposure to lesser noise can destroy the tiny hair cells – known as cilia – that grow in the ear canal.” Hair cells are destroyed, but in the inner ear (the cochlea) along an anatomical structure called the Basilar membrane. Along with cerumen (ear wax), the cilia in the ear canal play a role in keeping the ear canal free of debris.
