Sound and Vibration
VEHICLES AND INFRASTRUCTURES
- Understanding, Control and Reduction of Environmental Noise as a main objective and policy;
- Including general transportation (terrestrial, sea, air) as the main source sound and vibration;
- Build a project around the “Environmental Noise ” divided in four specializations:
- System vehicle,
- Individual components of the vehicle,
- Materials used
- Infrastructure for Transportation.
The 4 specialties are the issues to consider to keep control and reduction of the “Environmental Noise”.
The common solution is very complex and involves many scientific disciplines that are not directly associated with the acoustics, although the scientific transversality of this involves the considerable extent and deep.
The necessary expertise is not readily available in a single entity and require actions within partnership between specialists.
The example perhaps more representative of the vehicle system is definitely the car, without diminishing the importances of the other several means of transport (bus, train, ship, plane), as it is the car that started to study the problem of noise (and vibration) and have developed the most sophisticated techniques, that today are an integral part of the conception, development and implementation of a passenger vehicle with the acoustic requirements of quietness and comfort for passengers.
The acoustics of the means of transport by road (Automotive) is synthesized by the initials NVH (Noise, Vibration, Harshness) and typically represents the design phase, the simulation and the test prototype vehicles finals.
Skills, Resources, Facilities and extensive experience are essential and must be supported by a specific culture.
An example of a partnership is the “Italian Automotive Solution – IAS” for which Vibro-Acoustic acts as an up-front to potential international customers.
