QuickSIN · Quick Speech-in-Noise Test
What the patient does
The patient listens to recorded sentences presented with competing four-talker babble. Each sentence contains five key words, and the background noise grows more challenging as the signal-to-noise ratio decreases. The listener repeats back as much of each sentence as possible.
How it works
- Six sentences per standard list
- Five scored key words in each sentence
- Speech presented with four-talker babble
- Signal-to-noise ratio drops in 5 dB steps
- Yields a signal-to-noise ratio loss, or SNR loss
- Run through headphones or in a calibrated sound field, depending on the clinical purpose
What it evaluates
- Functional speech understanding in background noise
- How much acoustic advantage a listener needs versus an average normal-hearing adult reference
- Difficulty separating a target speaker from competing voices
- Real-world limits that may not appear during speech testing in quiet
Why it matters at school
It connects to understanding a teacher while classmates talk, following group activities, and hearing in cafeterias, gyms, auditoriums, and assemblies, especially from the back or side of a room. Poor speech-in-noise performance can happen for several reasons and is not, by itself, proof of CAPD.
