Pediatric audiology procedures
Often used with older infants and involves presenting a sound and seeing whether the infant will turn his or her head toward the sound. This response is measured by presenting sound from different directions and noting the infant's response.
What is visual reinforcement audiometry (VRA)?
The part of the ear where sound is diminished in conductive hearing loss.
What is the middle/inner ear?
This part of the ear may conduct sound efficiently to the inner ear, but damage to the hair cells of the cochlea or to the acoustic nerve prevents the brain from receiving the neural impulses of the sound.
What is the middle ear?
Mixed hearing loss occurs when neither the middle ear nor this part of the ear are functioning properly.
What is inner ear?
Hearing loss that is 90+ dB.
What is profound hearing loss?
Uses games and is often used for children between the ages of two and four years. For example, a child will be asked to drop a toy in a box every time a tone is heard.
What is conditioning play audiometry (CPA)?
A congenital malformation of the ear where the external canal is completely closed.
What is aural atresia?
Sensorineural loss is considered to be this type of hearing loss, because neither the damaged hair cells or the acoustic nerve is repairable.
What is permanent hearing loss?
A mixed loss affects both air and bone conduction, but this type of conduction is more affected than the other.
Hearing loss that is 66-89 dB.
What is severe hearing loss?
A test that is used when visual reinforcement audiometry is not possible. It is often used with infants who are less than six months of age or who are not able to turn their heads in the direction of a sound.
What is behavioral observation audiometry (BOA)?
A congenital malformation of the ear in which the pinna is very small and deformed.
What is microtia?
A hearing impairment in older people due to the effect of aging and is associated with sensorineural hearing loss. It affects high frequencies and patients have difficulty understanding speech, especially under challenging listening conditions, such as noisy parties.
What is presbycusis?
What is moderately severe hearing loss?
This type of hearing test includes behavioral observation, visual reinforcement, conditioned orientation response, conditioned play, and conventional audiometry, as well as speech audiometry.
What is behavioral hearing test?
Conductive hearing loss is never profound; there is always some hearing left because of this type of conduction created by the skull bones.
What is bone conduction?
A tumor that can develop on the acoustic nerve and cause sensorineural loss by slowing nerve conduction of sound impulses to the brain.
What is acoustic neuroma?
Hearing loss that is 41-55 dB.
What is moderate hearing loss?
This test includes acoustic immittance measures (for example, tympanometry, acoustic reflexes), Auditory Brainstem Response (ABR – including sedated and unsedated/infant ABR for hearing threshold assessment), and Otoacoustic emissions (OAE).
What is physiological auditory test?
An infection of the middle ear that is often associated with the upper-respiratory infections and eustachian tube dysfunction. If serious, treated with pressure equalizing tubes (PET).
What is otitis media?
The leading causes of sensorineural hearing loss in young and middle-aged American adults is this.
What is noise?
Hearing loss that is 16-40 dB.
What is mild hearing loss?
