speech perception in noise
A category of audiological testing that measures a patient's ability to understand speech when competing background noise is present, going beyond quiet-condition word recognition.
Full Definition
Speech perception in noise (SPIN) testing assesses the ability to understand spoken stimuli in the presence of a masking noise background, replicating the communicative challenges of real-world listening environments. Standard tests include the QuickSIN (Quick Speech-in-Noise test) and BKB-SIN. Results are typically expressed as the signal-to-noise ratio loss (SNR loss) in dB, indicating how much more favourable a signal-to-noise ratio the patient requires compared to a normal-hearing listener. Editors should note that this measure is more ecologically valid than word recognition scores in quiet and is increasingly required in hearing aid and cochlear implant outcome reports. The abbreviated form SPIN refers specifically to the original Speech Perception in Noise test; care should be taken when the acronym is used generically.
Usage
Usage note: The acronym SPIN technically refers to the specific Kalikow et al. test. When used generically, write 'speech perception in noise testing'. Report SNR loss in dB and specify the test tool used (e.g., QuickSIN, BKB-SIN).
