What is a normal word recognition score?

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 word recognition hearing?

A word recognition test (also called speech discrimination test) assesses a person’s ability to understand speech from background noise. If your speech discrimination is poor, speech may sound garbled. Word recognition scores can be helpful in predicting the usefulness of a hearing aid.

What is the purpose of performing word recognition testing in quiet?

To determine if the patient’s performance agrees with his or her pure-tone hearing loss. Are the findings consistent with what you would expect for someone with a cochlear pathology? To identify unusual asymmetry that is not predicted by the hearing loss. To monitor performance over time, through sequential testing.

What is the purpose of word recognition score?

Word recognition (WR) You can also score this as a phoneme score to know which phonemes the patient has difficulty hearing at a particular intensity level. This is helpful for counseling and rehabilitation purposes.

What is a normal speech recognition 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. The degree of hearing loss is grouped into five different categories, from “normal” to “profound hearing loss.”

What is the purpose of a word recognition test?

The purpose of word recognition testing is to determine the patient’s optimum performance, obtained in such a standardized way that it can be confidently enter our findings into the patient’s medical records.

What is poor speech discrimination?

Discrimination loss means that some speech sounds can’t be perceived by the ear and brain, making it difficult to distinguish between words and speech sounds – particularly those that are placed close to each other.

What does an audiogram tell?

The audiogram is a chart that shows the results of a hearing test. It shows how well you hear sounds in terms of frequency (high-pitched sounds versus low-pitched sounds) and intensity, or loudness.

What does an audiogram test for?

An audiometry exam tests your ability to hear sounds. Sounds vary, based on their loudness (intensity) and the speed of sound wave vibrations (tone). Hearing occurs when sound waves stimulate the nerves of the inner ear. The sound then travels along nerve pathways to the brain.

What is a good speech discrimination score?

The Speech Discrimination Test The number is the percent of words you repeated back to the audiometrist correctly. Normal speech discrimination is 100%, mild 85-95%, moderate 70-80%, poor 60-70%, very poor 40-50%, below 35% very severely impaired.

What causes poor speech discrimination?

Recruitment and poor speech discrimination result from center-clipping of the signal waveform applied to an involved hair cell, the direct corollary of partial, ciliary decoupling.

What is the articulation function of the PBK?

The PBK-50, also known as PBK, tests word recognition ability of lower grade school age children. The articulation function is approximately 4%/dB. There are three lists of 50 words (150 words total) available in four different randomizations. The PBK includes a) audio recording and b) printed word list.

When to use the BKB-sin hearing test?

The BKB-SIN (Speech In Noise) uses sentences in four-talker noise at varying signal-to-noise ratios. This test has also been used to determine cochlear implant candidacy. If traditional speech materials are too difficult to evaluate hearing ability in an adult cochlear implant patient, we recommend the Minimal Auditory Capabilities (MAC) Battery.

What’s the purpose of a word recognition test?

If you have ever participated in a hearing test and have been asked to repeat single syllable words with prompts like “say the word love” or “say the word burn”, then you’ve participated in a word recognition test. The purpose of this test is to measure, in terms of a percent, your optimal ability to process speech in a quiet setting.

What are the different types of speech recognition tests?

The Basic Auditory Tests Version V includes several popular test recordings at an INCREDIBLE PRICE! Version V includes: The NU-6, W-22, and PBK word lists are recorded on the left track, and the competing noise is on the right. This versatile recording can be administered for masking, speech in noise, or words in quiet.
