Release from Energetic Masking Caused by Repeated Patterns of Glimpsing Windows

Maury Lander-Portnoy


The study of auditory masking not only provides data for how healthy and impaired listeners perform in adverse listening conditions, and thereby approximates their ability to perceive speech in the noisy environments of everyday life, but also provides insights into the mechanisms that underly the detection and perception of speech. Previous studies, (Pollack 1955) (Festen & Plomp 1990) (Cooper et al. 2015), have manipulated noise maskers in an attempt to observe the relationship between modulation of the type or characteristics of masking noise to subjects ability to detect or recognize a target signal. In this experiment, long term average spectrum speech shaped noise maskers were modulated to allow either short or long glimpsing (Cooke 2005) windows, during which the target signal was unmasked, in one second long morse code patterns of eight windows. The results from 60 participants with normal hearing showed that subjects performed significantly better on trials of an open set word recognition task when the pattern of glimpsing windows repeated twice before presentation of the masked signal than a control with the same glimpsing windows during the signal but different beforehand and one with the same amount of noise masking in random patterns before and during the target.
