Thick, yellow or red coloured wax is produced by the ear canal to protect it. Sometimes this wax builds up.Have a look at the diagram below, why do you think this person cannot hear very well?The wax is preventing the oval window in the cochlea from vibrating properly.The wax has damaged the ear drum.The wax is blocking the air vibrations.The build up of wax is preventing the ear drum from vibrating properly.I DON'T KNOWSUBMIT ANSWER

You are performing Weber and Rinne hearing tests. For the Weber test, the sound lateralized to the unaffected ear; for the Rinne test, air conduction-to-bone conduction ratio is less than 2:1. You interpret these findings as suggestive ofGroup of answer choicesotitis externa.a defect in the middle ear in the semicurcular canalsimpacted cerumen.a defect in the inner ear to the cochlear nerve

When cleaning his ear canal with a cotton swab, Garrett pushes the swab into the external acoustic meatus as far as he can. When he is met with some resistance, he pushes harder and suddenly feels a sharp, intense pain. He then notices that all he can hear from that ear is a constant ringing. What damage has he most likely done to the ear?Multiple ChoiceHe has torn the oval window so sound vibrations are not being transmitted into the inner ear.He has torn the skin of the ear canal, and now blood is preventing sound waves from reaching the tympanic membrane.He has torn the tympanic membrane so sound is not being transmitted to the middle ear.He has damaged the stapes so sound vibrations are not being transmitted to the inner ear.

Jared has been an avid fan of rock music for many years and has attended numerous concerts, getting as close to the stage as possible. He has never worn earplugs or protective earwear. Now in his 50s, he has become hard-of-hearing and can no longer detect quiet sounds or low talking. How might his symptoms be explained?Multiple ChoiceHis tympanic membrane has hardened.He has developed a brain tumor that puts pressure on the vestibulocochlear nerve.He must have used the antibiotic streptomycin while at a concert which weakened the structures in his inner ear, making them less able to respond to sound waves.His hair cells are permanently damaged and desensitized to loud sounds.
