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 day to day
It connects to understanding conversation in restaurants, following group discussions, and hearing in meetings or lectures, 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.
