Ventac - Industrial Vehicles With Glass Cabs Headliners
Industrial vehicles with glass cabs are especially prone to high levels of reverberant noise . The high level of visibility required on these vehicles means large sheets of glass used. Unsurprisingly this will reflect the noise from the engine and hydraulics back and forth within the cab magnifying the noise. In addition to this, the panes of glass can resonate the structure borne noise and produce a standing wave within the cab space that peaks just at the operators head. All this means it is essential to introduce sound absorption into the cab interior wherever possible.
The cab headliner is one of the few feasible locations to reliably do this and it has the additional benefit of being close to the operators head. Ventac are developing and supplying headliners that are designed to be effective sound absorbers of this type of machinery noise. These products can not only improve the decibel level at the operator ear but greatly increase the vehicle comfort and are an important element in any vehicle cab noise reduction package.
