What does SRT mean on a hearing test?
About Speech Testing Speech testing will look at how well you listen to and repeat words. One test is the speech reception threshold, or SRT. The SRT is for older children and adults who can talk. The results are compared to pure-tone test results to help identify hearing loss.
What does SRT and WRS mean on a hearing test?
The speech recognition threshold (SRT) is the lowest level at which a person can identify a sound from a closed set list of disyllabic words. The word recognition score (WRS) testrequires a list of single syllable words unknown to the patient to be presented at the speech recognition threshold + 30 dBHL.
What range should the SRT be in based on this audiogram?
-10 to 25dB HL
An SRT is considered to be normal if it falls in the range of -10 to 25dB HL (Hearing Level).
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.
How is an SRT performed?
SRT: This test measures your speech reception threshold at decreasing volumes using a small set of words, which are revealed at the beginning of the test. These words will then be randomized and repeated at lower and lower decibel levels until you are unable to recognize and repeat which word you hear.
What is the difference between SRT and WRS?
The WRS shows how well the patient can hear and process speech signals at various supra-threshold levels; in contrast, the SRT indicates how sensitive the person is to hearing speech signals at specific barely perceptible levels.
What is the relationship between SRT and PTA?
The speech recognition threshold (SRT) is believed to be related primarily to the pure-tone average (PTA) and the steepness of the hearing loss. However, there are indications that it may also be influenced by perceptual or cognitive-linguistic factors, or both, such as meaningfulness of the speech stimuli.
Is 25 dB good hearing?
If you can only hear sounds when they are at 30 dB, you have a mild hearing loss. You have a moderate hearing loss if sounds are closer to 50 dB before you hear them….Degree of Hearing Loss.
| Degree of hearing loss | Hearing loss range (dB HL) |
|---|---|
| Slight | 16 to 25 |
| Mild | 26 to 40 |
| Moderate | 41 to 55 |
| Moderately severe | 56 to 70 |
What is a good speech discrimination score?
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.
How do you test an audio speech?
Your audiologist will ask you to repeat a list of words to determine your speech reception threshold (SRT) or the lowest volume at which you can hear and recognize speech. Then, the audiologist will measure speech discrimination — also called word recognition ability.
What does PTA mean on a hearing test?
pure-tone average
A convenient summary of the audiogram for each ear is the pure-tone average (PTA) of thresholds measured at specific frequencies. Thresholds are measured on a decibel (dB) hearing loss (HL) scale referenced to audiometric”zero” (the average hearing level at each frequency for normal young adults).
