Masker attenuation improves intelligibility more than equal target amplification

Evidence

But, the results showed that filtering the masker seemed to have a larger impact on speech intelligibility than filtering the target. SRTs were not symmetrical as the SNR was varied up or down with the same amount. The benefit was greater when the filtered part of the noise decreased rather than when the filtered part of the target increased. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3581

• XREF: Relates to positive-versus-negative SNR weighting — ties to the reader’s earlier finding that subjective loudness perception is nonlinear.
