describe two ways the middle ear amplifies sound
Homework Answers
The first amplification happens because of focussing the sound waves from tympanic membrane (ear drum) which has higher surface area to the oval window which has smaller area.
The second amplification happens because of lever actions of three ossicles i.e. malleus, incus and stapes.
When ear drum vibrates it moves the malleus side to side like lever which further moves incus, which further moves stapes and finally the oval window.

1. How do the ossicles of the middle ear transmit sound wave information to the inner ear? (e.g., explain how the movement of the bones changes based on frequency and amplitude) 2. Explain how frequency information is processed on the basilar membrane of the cochlea (e.g., describe what happens when you modify the frequency and amplitude of sound waves-where are they processed?) 3. What cells are responsible for transduction in the auditory system? Where are they located? How does transduction...

Hearing Acuity There are two possible types of hearing loss 1·Conductive hearing loss results from interference of sound conduction through the outer andor middle ear. 2. Sensorineural lhearing koss resules from damage to the inner ear or the vestibulocochlear nerve. Two clinical tests can help a healthcare professional determine if hearing loss is conductive or sensorineural: the Weber test and the Rinne...

As sound waves enter the ear, in what order do they reach the structures of the outer, middle and inner ear? A. pinna, auditory canal, tympanic membrane, ossicles, cochlea B. pinna, cochlea, auditory canal, tympanic membrane, ossicles C. auditory canal, ossicles, tympanic membrane, cochlea, pinna D. cochlea, ossicles, tympanic membrane, pinna, auditory canal

1. What two structures in the ear are involved in your sense of balance and in what part of the ear (outer, middle, inner) are they found? 2. When you hear something, mechanical vibrations enter your ear, are amplified, detected then changed into electrical impulses that are sent to your brain. Starting with the pinna and ending with the cochlear nerve, list all the structures all the structures required to perceive sound, in order.

There are two muscles in the middle ear (tensor tympani and stapedius). When faced with loud sounds these muscles contract, stiffening the vibration of the ossicles (the stapes is pulled from the oval window and the malleus is pulled from the ear drum). a) How does this protect against loud sounds? (5 pts) b) What type of neuron(s) and which part of the nervous system is likely involved? (5 pts)

When hit by a sound wave, hair cells in the ear, after an initial, transient motion, settle down to a steady oscillation. The amplitude, A, of this oscillation depends on the frequency of the sound wave, f, measured in hertz (Hz). The figure on the right shows the amplitude of the response of two different hairs (solid and dotted curves) to sounds of different frequencies. Suppose the hair cells are each connected to different neurons which start spiking if the...
