Question

PTS, or permanent threshold shift, is identified by a ringing, whistling or buzzing sound in the ears even though no loud sounds are present. This is called:

1) Tinnitus
2) Hyperacusis
3) Presbycusis
4) Meniere's disease

Answer 1

PTS, characterized by tinnitus, refers to permanent hearing damage. It can be caused by sensorineural hearing loss, often associated with Ménière's disease, which may require treatment with cochlear implants.

Step-by-step explanation:

Permanent threshold shift (PTS) is characterized by a persistent ringing, whistling, or buzzing sound in the ears when no external sound is present, which is known as tinnitus. This symptom can be an aspect of various underlying conditions, with one significant cause being sensorineural hearing loss. Sensorineural hearing loss can arise from inner ear damage or neural pathway issues and may be associated with diseases like Ménière's disease, which involves degeneration of inner ear structures. In addition to tinnitus, Ménière's disease can cause hearing loss, vertigo, and increased ear pressure. While hearing aids may not be effective for this kind of hearing loss, cochlear implants, which stimulate the auditory nerve directly, can sometimes serve as a treatment option.
