Better-ear glimpsing is an auditory process that takes advantage of short-term interaural level differences (ILDs) to improve the understanding of speech in spatial fluctuating noise. Since ILDs are mainly present at high frequencies, where most hearing-impaired (HI) listeners have the strongest hearing loss, HI individuals cannot fully utilize ILDs for better-ear glimpsing, which may lead to p...

Ears are a new biometric with major advantage in that they appear to maintain their shape with increased age. Any automatic biometric system needs enrolment to extract the target area from the background. In ear biometrics the inputs are often human head profile images. Furthermore ear biometrics is concerned with the effects of partial occlusion mostly caused by hair and earrings. We propose a...

Sound pressure measurements were made at the hearing aid microphones of 20 subjects with their in-the-ear (ITE) hearing aids and a behind-the-ear (BTE) hearing aid to determine the influence of microphone location on hearing aid input. A probe tube microphone was used to measure the difference in dB SPL between the ITE and BTE microphone locations. ITE microphone location resulted in a maximum ...

This paper presents a dichotic listening experiment on the perception of Mandarin tones under clean and noisy conditions. We examine the enhancing role of noise on the lateralization patterns of tones. We discover that the lateralization patterns of different tones are inconsistent: the perception of tone 1 exhibits a left ear advantage, while that of tone 2 or tone 4 has a right ear advantage....

Laterality in the perception of non-stationary aspects of musical timbre was investigated in 54 right-handed non-musicians. Timbre differences were produced by altering the amplitude envelope of a steady-state complex tone. Two single-choice tests with attention directed to one ear were used--a dichotic test and a monaural test with contralateral white noise. Dependent variables were reaction t...

Previous research has demonstrated that psychopaths exhibit abnormal language lateralization, and it has been proposed that psychopaths may be characterized by abnormal processing asymmetries in other domains as well [Hare, (1998). Psychopathy, affect, and behavior. In D. J. Cooke, A. E. Forth, & R. D. Hare (Eds.), Psychopathy: theory, research and implications for society (pp. 105–137). Nether...

The aims of the present study are to investigate: (1) the effect of using a hearing aid (HA) or a second cochlear implant (2nd CI) on speech recognition in noise for children; (2) the ability to perceive phoneme groups of different frequencies when using a CI and an HA in opposite ears (bimodal fitting) and when using a CI in each ear (bilateral implant fitting), and (3) the relationship betwee...
