Shipboard Noise Control - Vipac's acoustic consulting services are used for proposed and existing vessels to improve crew and passenger comfort, meet tender specifications and provide a marketing edge over competitor's vessels. Through state-of-the-art structure-borne-noise modelling and empirical database information, complex predictions of noise levels can be made from the designers drawings. This allows the noise control treatments to be identified, optimised, costed and integrated into the overall planning of the vessel construction. In-house laboratory facilities are also available for the testing of acoustic treatments and materials.
Underwater Acoustics - Vipac's engineers are experienced in underwater acoustics
through projects concerning buoyant fibre towed arrays for surveillance and seismic
exploration, fixed hydrophone arrays for vessel classification, and hydrodynamic
noise analyses. Mechanical vibration (sensed as radiated underwater noise) has
long been an indicator of the condition of mechanical systems and structures.
It is now one of the principle design considerations in the detectability and
survivability of military vessels. Vipac is working on projects to minimise noise
signatures from naval and ocean research vessels.
Sea Trial Testing - Vipac maintains a wide range of instrumentation, including sound level and intensity systems, hydrophones, multi-channel data acquisition systems, sophisticated multi-channel signal analysers and accelerometers, pressure and torsional transducers.
