SDT will be 10-12 less than SRT except in audiogram rises in High Frequency, SDT will be +/- 5 of the best threshold Recognition or understanding of the speech stimuli does not occur until about 7 -9 dB above the level of detection

Speech detection threshold (SDT) The speech detection threshold (SDT), also known as the speech reception threshold, is the level at which the patient can hear speech is present in 50% of the cases. You can use the SDT as a cross-check of air conduction audiometry, which should closely agree with the pure‑tone average (PTA).

Clinical Procedure For SDT & SRT. The patient is fitted with a headphone or speakers are used for the test. Our audiologist will use ascending or descending method to assess patients in identifying the words (descending “10 dB down & 5 dB up” and ascending “10 dB up & 5 dB down). The words used to assess patients are generally spondaic words.

Speech audiogram 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 number of correct words is scored out of the number of presented words to give the WRS. ... (SRT), within 5 dB, and the speech detection threshold (SDT), within 6–8 dB. 36 Related ...

The SDT is most commonly performed on those individuals who have been unable to complete an SRT, such as very young children. Because recognition is not required in the speech detection task, it is expected that the SDT will be about 5 to 10 dB better than the SRT, which requires recognition of the material.

Profound loss: 90 dB or more. The graph to the left represents a blank audiogram illustrates the degrees of hearing loss listed above. Frequency is plotted at the top of the graph, ranging from low frequencies (250 Hz) on the left to high frequencies (8000 Hz) on the right. Sound level, in dB, is plotted on the left side of the graph and ranges ...
