Mr. Williams most like has presbycusis which is hearing loss from old age since he is 69 years old. Also, since he cannot he his wife when she is speaking he probably has a high frequency hearing loss which is a very common sign of presbycusis. The reason why he cannot hear his wife when she is speaking but can hear his guy’s friends because he cannot hear higher frequencies. This since he has a high sensorineural hearing loss this means he as hair cell loss at the basal end of the cochlea. .

Also, when he did pure done testing, it showed he had within normal hearing for till 1k hz. …show more content…
This nerve plays an extremely important role in many functions however the most important is swallowing and phonation. The vagus nerve has many branches which goes to many different organs of the body. The vagus has 3 main branches, the pharyngeal, superior laryngeal, and recurrent laryngeal nerves. That are very important to phonation. The pharyngeal nerve innervates muscles of the soft palate and the pharynx. The superior laryngeal and the recurrent laryngeal nerves carry nerve impulses to the laryngeal nerves. The recurrent laryngeal nerves innervates all the intrinsic muscles of the larynx except for the cricothyroid. The recurrent laryngeal nerve is not symmetrical on the right and left side. The recurrent laryngeal nerve descends to the chest then go up to the
