What type of sounds does the attenuation reflex, involving contraction of the stapedius and tensor tympani muscles, primarily reduce the conduction of?
Explanation
The middle ear contains a protective mechanism called the attenuation reflex. This question tests the understanding of what kind of sounds this reflex is most effective against, which is important for protecting the cochlea and for improving perception of higher-frequency sounds (like speech) in noisy environments.
