Audiology as a Profession
He is known as the father of audiology.
Who is Raymond Carhart?
This is the subjective term for intensity and is measured in phons.
What is loudness?
In this method, an audiologist would go down 10 dB when a patient hears the tone, and up 5 dB when a patient does not hear the tone.
What is the Hughson-Westlake Method?
Masking involves the presentation of sound to this ear.
What is the Non Test Ear?
Tympanometry is this type of test, meaning it doesn't rely on patient factors like behavioral audiometry does.
What is objective?
He won the Nobel prize in 1961 in physiology for work on how ear functions.
Who is Von Bekesy?
This is the lowest frequency we can hear, although it is perceived as more of a vibration than a sound.
What is 2Hz?
You start with this ear when testing bone conduction.
What is the poorer hearing ear?
This is the interaural attenuation for insert earphones.
What is 60 dB?
Probe tips in tympanometry need to form this type of seal.
What is a hermetic seal?
She is known as the mother of pediatric audiology.
Who is Marion Downs?
This is an indicator of a patient's hearing level and is described as dB above their hearing threshold.
What is dB SL?
This type of hearing loss would give a range of Word Recognition Scores from 80-100%.
What is a Conductive Hearing Loss?
This occurs when the stimulus sound is audible in the non-test ear.
What is Cross Hearing?
The instrumentation for tympanometry includes a loudspeaker to produce the tone, a microphone to record sound from the tympanic membrane, and this device that changes air pressure.
What is a manometer?
Audiology as a profession arose during this war when soldiers returned with noise-induced hearing loss.
What is World War II?
This institute is responsible for ensuring proper calibration of equipment.
What is ANSI?
This is defined as the softest level a patient hears a tone 50% of the time.
What is Hearing Threshold?
This is a term used to describe the reduction of sound as it crosses through the head from one ear to the other.
What is Inter-aural attenuation?
This type of tympanogram is characterized by increased compliance and normal pressure, and may be seen in a patient with ossicular chain discontinuity.
What is type Ad?
It wasn't until this decade when audiologists started dispensing hearing aids.
When was the 1970's?
This is used to describe the relationship between duration of sound and its detection by the auditory system of the listener.
What is temporal integration?
This stimuli is used for SRT.
What are spondees?
This method is used to solve the Masking Dilemma.
What is Sensorineural Acuity Level (SAL)?
An audiologist would look for this type of tympanogram to confirm that a child's PE tubes are working properly.
What is type B with high ear canal volume?
