Speech Perception in Noise
Also written as: SPIN — Speech Perception in Noise
A class of audiological tests measuring a patient's ability to understand speech when presented against a background of competing noise, reflecting real-world listening difficulties.
Full Definition
Speech perception in noise (SPIN) tests evaluate how well a listener can identify speech targets—words, sentences, or phonemes—embedded in noise at varying signal-to-noise ratios (SNRs). Results are clinically important because many patients with audiometrically mild losses report significant difficulty hearing in noisy environments, a gap that pure-tone audiometry alone does not capture. Common standardized tools include the SPIN test, QuickSIN, and the HINT (Hearing in Noise Test). Editors should not interchange 'speech perception in noise' with 'word recognition score', which is measured in quiet. SNR loss, expressed in dB, is the key metric reported in SPIN-type assessments.
Usage
Usage note: SPIN (the test battery) and SPIN (the concept) share the same acronym; clarify on first use which is intended.
