Interior Trim

Reverberant noise, particularly at the speech frequency range can affect the interior comfort and sound levels of the cab, and is caused by modules such as the glass cab. Ventac sound absorption liners, tuned to these specific frequencies are one of the solutions included within our noise control kits used to address these sound levels.

Engine Noise

The engine bay is considered a ‘hotspot’ for noise, sound pressure and structure borne vibrations that are passed into the passenger cab and the external environment. Minimising the operators exposure to high noise levels, through addressing noise sources such as the engine bay and hydraulics, can significantly reduce the overall noise levels of the truck and ensuring compliance with strict noise regulations. Ventac sound absorbers perform well at the frequencies generated by diesel engines and Ventac also offer electric motor solutions to minimise annoying high frequency noise. Solutions are treated to ensure they are tough enough to endure and last in harsh environments.

Cabin Noise

The glass enclosure of the vehicle cab can amplify noise due to reverberation. This can be intensified within the normal frequency of the cab. Additional noise sources such as vehicle acceleration and vibration can have a negative effects on comfort and the operators health and safety. Ventac’s tuned composite materials and product solutions are designed to address key noise issues in vehicle cabs, particularly at the speech frequency which is key for communication, comfort and concentration.

Headliner Noise

A major part of increased productivity is focused on increasing comfort levels within the cab so that the operator can complete large applications and operations. The roof panel of the cab can be treated with acoustic absorption and barrier solutions to better isolate the cabin structure. Ventac sound absorbers reduce the noise that is close to the operators head and reduces overall cabin noise.

Hydraulics

Pump pressure, speed and size will have an effect on hydraulic noise and this generated noise can be amplified throughout the entire structure of the vehicle, its components and modules. These areas can react and create even higher noise sources, which has a negative impact on the overall sound performance of the vehicle. To effectively treat this area the noise path must be identified through Ventac’s Vehicle Acoustic Test Program so that the correct treatment can be identified.
