Perceptual Errors Support the Notion of Masking by Object Substitution [PDF]

Perception, 2019
Two experiments examined the effect of object substitution masking (OSM) on the perceptual errors in reporting the orientation of a target. In Experiment 1, a four-dot trailing mask was compared with a simultaneous-noise mask. In Experiment 2, the four-dot and noise masks were factorially varied.

Effectiveness of Two-Talker Maskers That Differ in Talker Congruity and Perceptual Similarity to the Target Speech

Trends in Hearing, 2017
Previous work has shown that masked-sentence recognition is particularly poor when the masker is composed of two competing talkers, a finding that is attributed to informational masking.

Development of Auditory Selective Attention: Why Children Struggle to Hear in Noisy Environments [PDF]

, 2015
Children’s hearing deteriorates markedly in the presence of unpredictable noise. To explore why, 187 school-age children (4–11 years) and 15 adults performed a tone-in-noise detection task, in which the masking noise varied randomly between every ...

Neural Correlates of Auditory Perceptual Awareness and Release from Informational Masking Recorded Directly from Human Cortex: A Case Study

Frontiers in Neuroscience, 2016
In complex acoustic environments, even salient supra-threshold sounds sometimes go unperceived, a phenomenon known as informational masking. The neural basis of informational masking (and its release) has not been well characterized, particularly outside

Effects of noise suppression and envelope dynamic range compression on the intelligibility of vocoded sentences for a tonal language [PDF]

, 2017
Vocoder simulation studies have suggested that the carrier signal type employed affects the intelligibility of vocoded speech. The present work further assessed how carrier signal type interacts with additional signal processing, namely, single-channel ...
