Soundproofing truck engines – reducing engine noise and vibrations
The engine is the most dominant source of noise in a truck and affects both the driver's working environment and overall driving comfort. Powerful vibrations, resonances, and airborne engine noise are transmitted through the chassis, bulkhead, and floor. With the right sound insulation of the engine compartment, both structure-borne noise and airborne noise can be effectively reduced, creating a quieter, more stable, and more professional driver environment.
Advantages of sound insulation for truck engines
Less engine noise in the cab
Sound insulation limits noise that would otherwise penetrate through the firewall and floor.
Reduced vibrations
Vibration damping reduces structure-borne noise from the engine and drivetrain.
Increased driving comfort
Lower noise levels create a quieter and more comfortable working environment.
Reduced driver fatigue
Less noise contributes to better concentration during long driving shifts.
More stable construction
Damping reduces resonance in sheet metal, panels, and fastenings.
Higher perceived quality
A quieter truck is perceived as more solid and well-built.
Areas of application for sound insulation in truck engines
Torpedo wall
Limits sound transmission between the engine compartment and the cab.
Floor above the engine
Dampens vibrations and noise transmitted via the chassis.
Engine covers and hoods
Reduces resonance in plastic and sheet metal.
Side and rear engine panels
Reduces noise propagating rearward in the cab.
Grommets and connections
Reduces sound leakage around cables and pipes.
Flexible solutions adapted for the truck's engine compartment
SilentDirect's products are designed to withstand high temperatures and powerful vibrations:
Vibration-damping materials
SilentDirect Polaric and SilentDirect Neo are applied to sheet metal surfaces to reduce structure-borne noise from the engine.
Sound-absorbing material
SilentDirect Egg is used in enclosed engine compartments where sound would otherwise build up.
Sound insulation against airborne noise
SilentDirect MLV is used as a barrier to block engine noise from entering the cab.
Sealing and vibration control
SilentDirect Seal is used to seal joints and stabilize components around the engine compartment.
