PB max: is the maximum score on the PI-PB - Word recognition score improve as intensity increase. Roll over – is a reduction of speech recognition scores that occurs at intensities above the level where PB max is obtained.

Just so, what are Pb words?

PB list of words consist of a group of single syllable words so selected that the frequency of occurance of speech sounds within the group is the same as the frequency of occurance of the same sounds in an average vocabulary of conversational language material.

Also, what is SDT in audiology? The speech detection threshold (SDT), also termed the speech awareness threshold (SAT), is the lowest intensity speech stimulus that an individual can detect at least 50% of the time. Word lists are phonetically balanced (PB), meaning that the speech sounds used occur with the same frequency as in the whole language.

Moreover, what is WRS in audiology?

Hi Onda, if you see “WRS” on your hearing test, that just means word recognition score. This refers to the percentage of the words you understood from the words said to you during the test. If you have a low word recognition score it can mean many things, but in most cases, hearing aids are helpful.

What is a normal word recognition score?

Speech audiogram The number of correct words is scored out of the number of presented words to give the WRS. A score of 85-100% correct is considered normal when pure tone thresholds are normal (A), but it is common for WRS to decrease with increasing sensorineural hearing loss.

What is a speech discrimination test?

A speech discrimination test assesses how well you understand words. For this test, the audiologist has you listen to words through the headphones at a decibel level louder than your speech reception threshold, so you won't have any problem with the volume of the speech.

What are CNC words?

Introduction. The Consonant-Nucleus-Consonant (CNC) word lists, included in the Minimum Speech Test Battery for Adult Cochlear Implant Users (Luxford, 2001), are considered the gold standard in the testing and management of cochlear implant (CI) users.

What is the Maryland CNC test?

The Maryland CNC test measures hearing loss using a 50-word exam that is designed to score how well you recognize the spoken word. The results of the Maryland CNC test helps the VA determine your hearing damage, whether the severity of the damage qualifies for VA disability payments, etc.

What is a phonetically balanced word list?

phonetic balance. that property by which a group of words used in the measurement of hearing has the various phonemes occurring at approximately the same frequency at which they occur in ordinary conversation in that language; phonetically balanced word lists are used in determining the discrimination score.

How do you calculate pure tone average?


Hearing sensitivity within the speech frequencies is known as the pure-tone average (PTA) and can be calculated by adding the thresholds obtained at 500, 1000, and 2000Hz and dividing the result by 3. For audiometric results to be valid, the patient must respond to stimulation of the ear being tested.

What does SRT mean on a hearing test?

Speech Reception Threshold

What is speech recognition threshold?

Speech Threshold Definitions
Speech Recognition Threshold (SRT). The speech recognition threshold is the minimum hearing level for speech (ANSI, 2010) at which an individual can recognize 50% of the speech material. Speech recognition thresholds are achieved in each ear.

Why do audiologists use speech audiometry for diagnosis of hearing loss?

Types of Hearing Loss
Speech audiometry provides information on word recognition and about discomfort or tolerance to speech stimuli. Speech audiometry outcomes help also in setting the gain and maximum output of hearing aids for patients with moderate to severe hearing losses.

What is normal speech reception threshold?

Normal results would include air and bone thresholds of 25 dB or better, an MCL of approximately 50 dB, a Speech Reception Threshold of around 15 dB, a Word Recognition Score of 100% and type-A tympanometry.

What do the numbers mean in a hearing test?


Page Content. ???Results from a hearing test are displayed on an audiogram. An audiogram is a graph that shows the softest sounds a person can hear at different pitches or frequencies. The closer the marks are to the top of the graph, the softer the sounds that person can hear.

What is a speech test?

Speech testing is one of the more simple types of hearing loss tests used by audiologists. Speech testing measures the speech reception threshold of each ear. This type of test can be performed on older children and adults and helps to confirm the results of a pure-tone test.

How do you perform pure tone audiometry?

Threshold Measurement Procedure
  1. Beginning with a 1000-Hz tone, continuously on but completely attenuated, gradually increase the sound-pressure level of the tone until a response occurs.
  2. Present a 1000-Hz tone at a 30 dB hearing level (HL). If a clear response occurs, begin threshold measurement.

Why is speech audiometry performed?

Speech audiometry has become a fundamental tool in hearing-loss assessment. In addition, information gained by speech audiometry can help determine proper gain and maximum output of hearing aids and other amplifying devices for patients with significant hearing losses and help assess how well they hear in noise.

What is PTA test for ear?

MeSH. D001301. Pure tone audiometry or pure-tone audiometry is the main hearing test used to identify hearing threshold levels of an individual, enabling determination of the degree, type and configuration of a hearing loss and thus providing a basis for diagnosis and management.

What is a good hearing test score?


40 dB sounds twice as loud as 30 dB and 8 times as loud as 10 dB (10 to 20 to 30 to 40 = 2 x 2 x 2 = 8). Normal hearing ranges from 0 to 20 dB in all frequencies. From here on, the assumption is that you have a sensorineural hearing loss (that you have nerve damage to the inner ear).

What is recruitment in hearing loss?

Recruitment refers to a condition related to some hearing loss. Recruitment causes your perception of sound to be exaggerated. Even though there is only a small increase in the noise levels, sound may seem much louder and it can distort and cause discomfort.

What is a normal audiogram?

Audiograms are set out with frequency in hertz (Hz) on the horizontal axis, most commonly on a logarithmic scale, and a linear dBHL scale on the vertical axis. For humans, normal hearing is between −10 dB(HL) and 15 dB(HL), although 0 dB from 250 Hz to 8 kHz is deemed to be 'average' normal hearing.
