Type of HL
Hearing loss involving the outer and/or middle ear.
What is conductive hearing loss?
Conversion of acoustic energy to electric energy
The purpose of case history is to determine the patients...
The chief complaint.
The softest speech sound a person can hear, but not repeat back.
Speech Detection Threshold
Average conversational volume
50-60 dB
Hearing loss involving the inner ear.
What is sensorineural hearing loss?
The middle ear using a lever system to increase the dB level of sound.
Impedence Matching
When you are checking for an obstruction in the ear canal, you are performing...
Otoscopy
The softest sound a person can repeat back words.
Speech reception threshold.
The softest sound a patient hears 50% of the time
Hearing thresholds
Combination of conductive and sensorineural hearing loss.
What is mixed hearing loss?
Outer Ear
Physiological measure of acoustic admittance.
What is tympanometry?
Used to validate the pure tone audiogram
SRT/SDT
The softest sound you can hear to the loudest sound you can tolerate
Dynamic range of hearing
Presbycusis is typically this type of hearing loss
Sensorineural
Movement of basilar membrane, rubs the hair cells against tectorial membrane
Mechanotransduction
Used when checking for an acoustic neuroma. The testing involves a loud noise for 10 seconds.
Reflex Decay
Testing to see how many words the patient understands.
Word recognition testing
Human range of hearing
20-20,000 Hz
Wax blockage is this type of hearing loss
Conductive
The basilar membrane is located in this portion of the cochlear (scala...)
Scala Media
Cause of seeing bubbles on the eardrum during otoscopy
Serous Otitis Media
When a patient performs worse on word recognition testing when a loud volume is presented compared to a comfortable volume.
Rollover
Air conduction shows type or configuration?
