Definition
| assessment of a client's hearing using speech stimuli |
|
|
Term
|
Definition
| refers to the degree to which a measuring tool identifies individuals who have a specific condition |
|
|
Term
|
Definition
| an audiologist's goal of determining in which part of the auditory system the disorder lies |
|
|
Term
| monitored live voice testing |
|
Definition
| method of performing speech audiometry in which the audiologist presents words through the microphone of the audiometer |
|
|
Term
| speech recognition threshold (SRT) |
|
Definition
| the minimum hearing level for speech at which an individual can recognize 50 percent of the speech material |
|
|
Term
|
Definition
| two-syllable word with equal stress on each syllable, used in SRT testing |
|
|
Term
|
Definition
| filtered broad band noise designed to simulate the long-term average spectrum of conversational speech, used in masking during speech audiometry |
|
|
Term
|
Definition
| display on the audiometer that provides information regarding the intensity of the input signal, typically has a range from -20 dB to +3 dB |
|
|
Term
| word recognition (WR) score |
|
Definition
| measure of speech audiometry that assesses a client's ability to identify one-syllable words presented at hearing levels that are above threshold |
|
|
Term
| speech detection (awareness) threshold (SDT) |
|
Definition
| the minimum hearing level for speech at which an individual can just discern the presence of speech material 50 percent |
|
|
Term
|
Definition
|
|
Term
| phonetically balanced word list |
|
Definition
| word list in which the sounds represented occur proportionally to their occurrence in spoken English |
|
|
Term
| performance intensity (PI) |
|
Definition
| percentage of speech understood at a variety of intensity levels from near threshold to well above threshold |
|
|
Term
|
Definition
| phenomenon that occurs when increasing intensity results in decreasing word recognition, the formula is PB Max - PB Min/PB Max, values at 0.25 to 0.45 can be significant for retrocochlear pathology |
|
|
Term
|
Definition
| auditory dysfunction that is beyond the cochlea in the auditory nerve or brain stem |
|
|
Term
| most comfortable level (MCL) |
|
Definition
| intensity level at which the client perceives speech or other stimuli to be most comfortable |
|
|
Term
| loudness discomfort level (LDL) |
|
Definition
| the level at which the client perceives speech or other stimuli (pure tones) to be uncomfortable to listen to |
|
|
Term
|
Definition
| decibel difference between the threshold of sensitivity and the loudness discomfort level, can be measured using speech or tones at discrete frequencies, reduced in cases of cochlear hearing loss with abnormal loudness growth |
|
|
Term
|
Definition
| intensity relationship between signal and noise, subtract the level of noise from the level of the of the speech |
|
|
Term
|
Definition
| feature of speech audiometry test in which the client chooses the correct response from a given set of choices |
|
|
Term
|
Definition
| broad spectrum noise sometimes used in masking during speech audiometry |
