Tone-in-noise detection tasks with reproducible noise maskers have been used to identify cues that listeners use to detect signals in noisy environments. Previous studies have shown that energy, envelope, and fine-structure cues are significantly correlated to listeners' performance for detection of a 500-Hz tone in noise. In this study, envelope ...

Graphene is an attractive photoconductive material for optical detection due to its broad absorption spectrum and ultra-short response time. However, it remains a great challenge to achieve high responsivity in graphene detectors because of graphene's weak optical absorption (only 2.3% in the monolayer graphene sheet) and short photo-carrier lifetime (< ...

Perception of sound laterality (left-right angle) is mediated by both interaural time differences (ITD) and interaural level differences (ILD). Previous localization studies in anechoic settings consistently show that low-frequency ITDs dominate perception of source laterality. However, reverberant energy differentially degrades ITDs and ILDs; the effects of room reflections on the ...

A sound's duration provides important information about the event producing it. Although many of the sounds we hear every day are 'percussive' in nature (ie resulting from two objects impacting) and therefore exhibit decaying/damped amplitude envelopes, perceptual experiments frequently use tones synthesized with 'flat' or abruptly ending envelopes. Such sounds ...
