Volvo has launched in its Torslanda factory in Gothenburg, his new acoustic laboratory. Facilities designed to achieve the best standards of safety and comfort from the point of view (though what is at stake is the ear) of the noises and sounds emitted by a vehicle. One study that will take them longer to find the sound of your new plug-in hybrid model based on the V70 and scheduled for 2012. A difficult job has yet to be defined as legally how quiet can and should be an electric car. No less than 60 people work at the center NVH Centers (Noise, Vibration and Harshness) in Torslanda, with a mission to get the best sounds for models of the Swedish brand, a task that has been called "Sound Design".
The work focuses on three areas: the elimination of irritating noises coming from the body elements, easy to listen sounds "information" that may come from the motor or control switches and, of course, get the characteristic sounds brand, as the engine, exhaust or noise of the doors when closing. Special attention is paid to drive, looking for a comfortable sound when driving at constant speed that is clearly distinct from that heard on the stages acceleration.
But his main challenge will be getting a proper sound for the future Plug-in Hybrid from Swedish home. The problem lies mainly in the phases of electrical work, so quiet you can hear over the noise nuisance, besides being an issue to take into account for road safety. In Europe there is still no legislation in this regard, but we have to find a compromise between the noise need not to be a danger to some users (especially pedestrians) and the possibility of reducing noise pollution caused by the traffic.
