Conductive hearing loss
Hearing loss or impairment resulting from interference with the transmission of sound waves through the outer and middle ear.
What is compromised in conductive hearing loss?
The ability to hear faint or soft sounds
Sensorineural hearing loss
Hearing loss or impairment resulting from problems with the auditory nerves- specifically stereociliary hairs in the cochlea
What is compromised in sensorineural hearing loss?
The ability to hear specific frequencies of sound
What is a Pure Tone Test?
An audiometer plays sounds at different frequencies at different loudnesses. The softest tone that one can hear is called the threshold
A graphic representation of vibration frequency and the minimim soind intensity for hearing.
An electrical prosthetic device that enables individuals with sensorineural hearing loss to recognize some sounds and that consists of an external microphone and speech processor that receive and convert sound waves into electrical signals which are transmitted to one or more electrodes implanted in the cochlea where they stimulate the auditory nerve.
An electronic device usually worn by a person for amplifying sound before it reaches the receptor organ.
The essential part of the vertebrate organ of hearing and equilibrium that includes the vestibule, the semicircular canals, and the cochlea.
The intermediate portion of the ear containing a chain of three ossicles that extends from the tympanic membrane to the oval window and transmits vibrations to the inner ear.
The outer visible portion of the ear that collects and directors sound waves toward the tympanic membrane by way of a canal which extends inward through the temporal bone.
Mechanical energy that is transmitted by longitudinal pressure waves in a medium (such as water or air)
What is a Rinne Test
512 Hz tuning fork is used on mastoid bone
What is a normal Rinne Test finding
Normal hearing clients will note air conduction twice as long as bone conduction
How does conductive hearing loss appear on a Rinne Test?
Bone conduction sound is heard longer than or equally as long as air conduction
How does sensorineural hearing loss appear on a Rinne Test?
air conduction is heard longer than bone conduction in affected ear, but less than 2:1 ratio
What can you learn from a speech-in-noise test?
People with sensorineural hearing loss can sometimes have a difficult time understanding speech in the presence of background noise.
What is tinnitus?
the perception of sound when no actual external noise is present.
