Abstract

Fast-acting amplitude compression is used extensively in the professional audio industry. Such compression can impede perception of the independent sound sources within a complex signal. However, listeners may partially compensate for this by using greater mental effort. To test this idea, young, normal-hearing university students were required to report the keywords from two simultaneously presented sentences, either with or without a secondary task. The sentences were uncompressed or were compressed by moderate or severe amounts. When the secondary task was required, the time taken to perform the tasks increased with increasing amount of compression, demonstrating that the listeners were near
the limit of the mental effort that they could expend. Measured effects disappeared gradually with increased experience of the tasks.
