At what level are speech recognition thresholds (SRT) typically measured?

Speech recognition thresholds (SRT) are typically measured at around 30 dB HL (Hearing Level). This level is chosen because it is generally near the softest level at which an individual can detect speech while still being able to respond correctly. At this threshold, the individual has enough acoustic information to process and recognize speech, making it a practical and clinically relevant point of measurement.

Measuring SRT at this level allows clinicians to assess how well a patient can understand speech in quiet conditions, which is crucial for fitting hearing aids properly and for developing appropriate rehabilitation strategies. It reflects the threshold of hearing in relation to speech sounds rather than pure tones, thus providing a more tailored evaluation of hearing capabilities that directly relates to communication skills.
