Structure-borne sound occurs when vibrations from the track, road surface, engines or drive systems propagate through the vehicle’s framework. This can result in noise within the passenger compartment that is perceived as muffled rumbling or resonances.
Antiphon addresses disruptive noise with products such as antiphon® MPM™ sheets and LD™ pads, which dampen vibrations in the chassis, floor and walls by converting kinetic energy into heat.
Airborne sound originates from engines, gearboxes, tyres, track contact, and external sources that penetrate the passenger compartment.
To reduce these, Antiphon’s sound-insulating and sealing materials, such as LT-F, are used to prevent noise from entering through joints, doors, and panels. Additionally, sound-absorbing materials such as LA and LA LV are applied to walls, ceilings, and engine compartments to minimise reflections and dampen noise levels.
Aerodynamic noise occurs at high speeds, especially in trains and buses, when airflows around the vehicle body generate turbulence and wind noise. By combining sealing materials with absorbing solutions in the bodywork and ventilation ducts, Antiphon's products help to reduce noise.
Installation noise, which arises from fans, cooling systems, door mechanisms and air compressors, can be particularly disruptive in quiet electric vehicles. Here, Antiphon's vibration-damping and insulating materials are used to separate components from load-bearing structures and reduce the transmission of noise and vibrations.
