4. Examine the consequences to sound perception if the tympanic membrane increased twofold in surface area. What would happen if the oval window had increased surface area? Would sounds be perceived if the round window became rigid?
The tympanic membrane is also known as the eardrum. If the tympanic membrane increased twofold, then it would be able to receive more vibrations thus increasing the sound pressure. This sends stronger vibrations all throughout the middle ear and then the inner ear. Therefore sound perception would be amplified. If the oval window had an increased surface area, then the sound waves would pass directly into the middle air, therefore the sound pressure which causes the tympanic membrane to vibrate would be reduced. Therefore it would reduce sound perception.
Basically, sound is created when vibrations in the air or sound waves in the air causes the tympanic membrane in the air to move back and forth. Therefore if the oval window becomes rigid, it would no longer be flexible enough to move back and forth when it is impacted by the sound waves. When this happens the ossicles cannot be moved and no sound can be perceived.
5. How successful are cochlear implants? What surgical techniques are employed?
A cochlear implant is a surgically implanted device which helps to bypass problems of the inner ear and the cochlea. Almost everyone who had received cochlear implants is able to hear some amount of sound. Children who have received the implants are able to hear normal speech levels at 30 or 40 decibels according to a research done by Dr. Bruce Gantz of the University of Iowa Hospitals and Clinics. It is more successful among individuals with complete hearing loss and has not benefitted form hearing aids.
Cochlear implants bypass damaged hair cells and convert sounds into electrical signals and send these signals to the hearing nerve. The internal component of the device is surgically implanted under the skin behind the ear and connected to

    Auditory neuropathy is a hearing disorder in which sound enters the inner ear normally but the transmission of signals from the inner ear to the brain is impaired. It can affect people of all ages, from infancy through adulthood. The number of people affected by auditory neuropathy is not known, but the condition affects a relatively small percentage of people who are deaf or hearing-impaired. Symptoms and Diagnosis People with auditory neuropathy may have normal hearing, or hearing loss…

    the environment stimulates the receptor cells in whichever sense organ is being used. If this information were auditory, the ear would convert sound waves in the air into electrical impulses that would further be interpreted by the brain as sound. A sound wave first enters the pinna, the fleshy part of the ear on the outside of the body. It then travels through the external auditory canal where it then meets the eardrum, a thin membrane in the outer ear. The eardrum then vibrates in response to the…

The human body follows an internal clock or a circadian rhythm unconsciously and Miller, Carlson and McCauley (2013) tested if the internal clock could be entrained or synchronized with an asynchronous (single repetitive) tone while responding to stimuli on a computer screen. The first of three experiments examined how auditory entrainment or auditory synching affected visual attention (Miller…
