Step-by-step explanation:
The medical term for ringing in the ears is tinnitus, which matches option a. tinnitus from the choices provided. Ringing in the ears can be a symptom of various conditions, including Ménière's disease, which is associated with sensorineural hearing loss. Hearing aids are typically not effective for treating sensorineural hearing loss that results from conditions like Ménière's disease, but they might be effective in cases of conductive hearing loss. For sensorineural hearing loss, a cochlear implant might be considered as a treatment option. The loudness of sound is described as b. intensity level or decibel, while the three ossicles of the middle ear are known as the a. malleus, incus, and stapes or b. hammer, anvil, and stirrup. The cochlea contains receptors for the transduction of mechanical waves to electrical signals, enabling us to hear.
