Speech Reception Threshold
Also written as: SRT — Speech Reception Threshold
The lowest intensity level at which a patient can correctly repeat 50% of spondee words presented during a speech audiometry test.
Full Definition
The speech reception threshold (SRT) is a fundamental speech audiometry measure that identifies the softest level at which a listener can correctly identify 50% of two-syllable words with equal stress on each syllable (spondees). It serves as a cross-check for pure-tone audiometric thresholds, as the SRT should correlate closely with the pure-tone average across 500, 1000, and 2000 Hz. The SRT is reported in decibels hearing level (dB HL) and is used in both diagnostic and rehabilitative contexts. Editors must distinguish the SRT from the speech detection threshold (SDT), which reflects awareness of speech rather than understanding, and from QuickSIN or similar noise tests, which assess suprathreshold performance in background noise.
Usage
Usage note: Do not confuse with Speech Detection Threshold (SDT), which measures awareness rather than understanding. Expand SRT on first use.
