How does your brain determine the volume and pitch of sounds?

Question

Accepted Answer

Okay everyone, let's take a look at this practice problem. We have blank amplify the vibrations reaching the eardrums. So our answer will be something that amplifies vibrations. And recall that the eardrum is the membrane between the outer and the middle ear. So let's take a look at some of our answer choices. We have a panic membrane. Now recall the time. Panic membrane is also known as the ear drum and it vibrates when sound waves hit it. Therefore we can eliminate option A. As the correct answer. Then we have B. The cochlear the coakley is the stele shell like structure in the inner ear and it converts vibrations into electrical signals. Therefore it's incorrect because it does not amplify sound. Then we have c. Semicircular canals. The canals are also part of the inner ear like the cochlea but they contain receptors involved in maintaining our balance and not responsible for amplification of vibrations. And we can also eliminate options see as being the correct answer. Finally we have d obstacles. Recall that the obstacles are a group of three bones, the mallee asse, the Incas and the steep ease there in the middle ear and receive vibrations from the eardrum and amplify those vibrations. So option D will be our correct answer because it's the obstacles that amplify the vibrations that reach the eardrum. Okay, everyone, I hope this was helpful and I'll see you for the next practice problem
