The risk of noise induced hearing loss, when wearing a hearing protector, can only be calculated with the knowledge of the noise level at the protected ear. Several methods are available for calculating this level, from the hearing protectors' attenuation…

Unlike porous models developed for particular absorbing materials and frequency ranges, the Johnson-Champoux-Allard model is a generalized model for sound propagation in porous materials over a wide range of frequencies. This model is nowadays used widely across the acoustic research…

Shallow water acoustic response functions at high frequencies and large bandwidths exhibit spatio- temporal variability that depends greatly on the propagation media's volume and boundary conditions as well as system source-receiver motion. For this reason practical acoustic systems invariably must…

A passive acoustic localization method for tracking the movement of a clicking sperm whale in three-dimensions using data from just one hydrophone is demonstrated using data made available for the 3rd International Workshop on Detection and Classification of Marine Mammals.…

Over the last twenty years, many subjectively relevant objective room-acoustics quantities or indicators for evaluating the acoustical quality of an enclosure have been introduced. Whilst indicators give new insight into the acoustical goodness of a receiver position, there is still…

We propose a new method to localize low-frequency calls in 2D in shallow waters from a sparse array of hydrophones using modal propagation modelling. An analysis of modal propagation modelling of transients signals in shallow water environment shows that the…

To the best of our knowledge, all odontocetes produce some kind of click like vocalisation, which is used primarily for echolocation but may also play a role in social communication. Characteristics of these echolocation pulses range from the broad band…
