Question

A loud noise causes

Quizplus · Accepted Answer

A loud noise can cause all of the listed effects. The movement of the tympanic membrane (A) is responsible for transmitting the sound waves into the middle ear. An alerting reaction leading to sympathetic activation (B) is a common response to sudden loud noises. Reflex contractions of middle ear muscles (C), specifically the stapedius and tensor tympani muscles, can occur to reduce the transmission of loud sounds. And a large pressure pulse can enter the cochlear duct at the oval window (D), causing movement of the fluid within the cochlea and initiating the process of hearing.
