Answer to Question 1

Hearing changes often associated with aging include decreased hearing acuity, speech intelligibility, and pitch discrimination, which is referred to as presbycusis. Low-pitched sounds are easiest to hear, but it is difficult to hear conversation over background noise. A decrease in active sebaceous glands causes the cerumen to become dry and completely obstruct the external auditory canal. Tinnitus is commonly caused by ototoxicity and patients experience the sensation of ringing in the ears. Presbyopia refers to the gradual decline in ability of the lens to accommodate or focus on close objects and reduces ability to see near objects clearly. Although the cause of Mnire's disease is unknown the symptoms include progressive low-frequency hearing loss, vertigo, tinnitus, and a full feeling or pressure in the affected ear.
