Speech Perception in Noise
Also written as: SPIN — Speech Perception in Noise
A patient's ability to correctly identify or repeat spoken words or sentences when competing background noise is present, commonly assessed via standardized tests.
Full Definition
Speech perception in noise (SPIN) is a core functional measure in aural rehabilitation, evaluating how well an individual understands speech under adverse listening conditions that simulate real-world environments. It differs from quiet-condition speech recognition by introducing a competing noise signal, typically multi-talker babble or speech-shaped noise. Standardized assessments include the SPIN test, the QuickSIN, and the BKB-SIN. Results are often expressed as a signal-to-noise ratio loss score or percentage correct. Editors working on clinical trial reports, rehabilitation program descriptions, or outcome articles must ensure this term is not reduced simply to 'speech recognition,' as the noise component is diagnostically and rehabilitatively significant.
Usage
Usage note: When abbreviated, SPIN refers specifically to the psychoacoustic concept or the eponymous test battery; editors should clarify which meaning is intended on first use.
