Measuring communication effort in speech variability
(. Fourth International Conference on Cognitive Hearing Science for Communication (CHSCOM). Linköping, Sweden, 2017)Interactive conversation is one of the most important activities that is affected by hearing impairment. • Measures of effort are important, in terms of both listening and communication, in understanding hearing ... -
The mechanical properties of earmuffs
(2011)The physical properties of circum-aural hearing protectors, such as mass, clamping force and cup volume, have an influence on the attenuation performance of the device. This paper closely examines the physical and acoustic ... -
Medical practitioners’ attitudes to hearing rehabilitation for older adults
(2011)Objective: Medical practitioners have the potential to play a significant role in older adults’ help seeking behaviour in relation to hearing rehabilitation. The current study aimed to look at attitudinal factors that ... -
Metamaterial design for middle-low frequency elastic wave miti-gation
(2017)In the past two decades, meta-materials have drawn increasing attention from researchers due to their unique properties, including wave attenuation with potential application in acoustic engineering. A number of meta-material ... -
Monte Carlo model of acoustic response from a bubble cloud
(2017)In various sonar applications it is important to model the acoustic response of a bubble cloud to a sonar pulse of different types. In a typical approximate approach, a bubble cloud is modelled as a set of point scatterers. ... -
Music to whose ears? The effect of social norms on young people’s risk perceptions of hearing damage resulting from their music listening behaviour
(2012)Professional and community concerns about the potentially dangerous noise levels for common leisure activities has led to increased interest on providing hearing health information to participants. However, noise reduction ... -
NAL-NL2 empirical adjustments
(Trends Amplification, 2012)NAL-NL1, the first procedure from the National Acoustic Laboratories (NAL) for prescribing non-linear gain, was a purely theoretically-derived formula aimed at maximizing speech intelligibility for any input level of speech ... -

NAVAL APPLICATIONS OF MARINE ACOUSTICS
(2017)Both communities have interests (or requirements) that can be described by the parameters of time and space. The science and technology of Marine Acoustics, dependent on specific investigators and their focus, is not ... -
Near-field acoustic holography and non-negative intensity for prediciton of sound radiation
(Acoustics 2015 Hunter Valley 15-18 November 2015, 2015)Temperature inversion and wind conditions are known to have a significant effect on noise propagation over long distances. Consideration of such conditions is a challenging part of assessing environmental noise propagation ... -
The NOISE (Non-Occupational Incidents Situations and Events) Database: A new research tool
(2013)This paper describes the development of the NOISE (Non-Occupational Incidents Situations and Events) Database. The NOISE database currently contains 536 separate leisure activities and events, including noise level ...
