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 ... -
Noise exposure in the balance: Managing occupational and leisure risks to hearing health
(Journal of Health Safety and Environment, 2014)Health and safety risks that are present in both occupational and home/leisure environments can pose difficulties for health and safety professionals when determining risk mitigation responsibilities. Where work is defined ... -
Noise levels in fitness classes are still too high: Evidence from 1997-98 and 2009-11
(2013)Fitness instructors routinely use high music volumes which may be harmful to hearing. This study assessed noise levels during 35 low-intensity and 65 high-intensity fitness classes in 1997-98 and 2009-11. Questionnaires ... -
Noise with attitude: Influences on young people’s decisions to protect their hearing
(2013)Objective: To investigate young people’s experiences and attitudes towards hearing health and their participation in noise reduction behaviours, to better understand how education and prevention messages may be better ...
