Attentional processes in auditory discriminations
… the ability of human observers to monitor two earphone channels in order to perform one or two independent frequency discriminations. Performance (d′) was significantly poorer with dichotic stimulus presentation than in monaural control conditions. A detailed analysis of the data suggested that …

Speech intelligibility in tracked vehicles and pink noise under active noise reduction and passive attenuation communications headsets
… systems were in part the result of better earphone response characteristics in the principal speech bandwidth (600 - 4000 Hz) in conjunction with the strong attenuation performance of the David Clark headset in that same range. It is suggested that, in the absence of better earphone …

Performance and test-retest reliability of the digits-in-noise test used in the sound field
… test is completed with coupling to headphones/earphones. However, due to several limitations, such as the lack of availability or inability to utilise headphones/earphones, performing tests with earphones/headphones may not always be possible. Therefore, this study aimed to determine if the …

Actively exploiting propagation delay for acoustic systems
… different propagation delays at two ears using earphones. We develop algorithms that accurately track the 3D orientation of the head, a key enabler for designing 3D acoustics. In general, this dissertation shows that while propagation delay has been studied for a long time and for many …
