Hearing Flashcards
Between the outer, middle and inner ear which is responsible for absorbing sound?
Outer ear.
Between the outer, middle or inner ear which contain the ossicles?
Middle ear
The Eustachian tube serves to equalise -
the middle ear to atmospheric pressure
The inner ear contains two important pieces of equipment -
At for what is each responsible?
The Cochlea and the vestibular apparatus
The cochlea for translating sound waves into nerve pules and the vestibular apparatus for balance
Between the outer, middle or inner ear which contain the cochlea and vestibular apparatus?
The inner ear
The human hearing range is -
20 Hz to 20 000Hz
Between frequency or loudness(decibels) which is more significant to hearing loss?
Decibels
Exposure to noise levels in ______ of __dB can cause __________ hearing loss, whilst ______ exposure to noise levels above __dB can cause _________ hearing loss.
Exposure to noise levels in excess of 85dB can cause temporary hearing loss, whilst constant exposure to noise levels above 90dB can cause permanent hearing loss.
Exposure to noise levels in excess of __dB can cause __________ hearing loss, whilst ________ exposure to noise levels above __dB can cause _________ hearing loss.
Exposure to noise levels in excess of 85dB can cause temporary hearing loss, whilst constant exposure to noise levels above 90dB can cause permanent hearing loss.
The vestibular system comprises -
The otolith organs and the semi-circular canals
The semi-circular canals are filled with a fluid called -
Endolymph
The posterior canal sense -
The anterior canal sense -
The lateral canal senses -
Pitch
Roll
Yaw
The semi-circular canals detect -
The otolith organs can detect -
angular acceleration
Linear acceleration
The utricle and saccule(otolith organs) is contained within the -
Vestibule
