The role and application of the concept of the soundscape, vis-à-vis that of environmental noise management, needs elaboration. In noise control, sound is a waste product, managed to reduce the immision of sounds that cause human discomfort. The soundscape approach, by contrast, considers the acoustic environment as a resource, focussing on sounds people want, or prefer. Quiet is not a core req...

An efficient finite volume approach has been used to develop a three dimensional Helmholtz acoustic solver for complex geometries. This acoustic solver was utilized to obtain characteristic mode shapes and frequencies of a baffled combustion chamber. An experimental setup, including stationary and moving sensors, has also been used to measure these quantities for the same model combustion chamb...

Underwater sensor networks (UWSN) are considered to be feasible and suitable for several applications. However, the characteristics of the acoustic channel must be taken into account on the evaluation of the application feasibility. The acoustic channel imposes severe limitations to the communication, such as low bandwidth, low data rates and short practical transmission ranges. Applications wi...
