A higher required signal-to-noise ratio indicates worse speech-in-noise performance.
Evidence
The average SNR loss was calculated across the six lists. This score indicates the increase in SNR required for the participant to understand the sentence compared with a normal hearing person. Any score less than 4 dB is considered normal, and a lower SNR loss score reflects better speech-in-noise performance. — Dijk, Pim van, Physiology, Psychoacoustics and…, 4172
