BODY AND EXTERIOR
4. Quietness
Silencers, dual-wall panels, sound-absorbing materials,
etc . are utilized in conjunction with a high-rigidity and
vibration/noise-proof body structure in order to provide
a quiet passenger compartment .
1 ) Dual-wall toeboard
The toeboard is a dual-wall design consisting of an
asphalt sheet placed between two steel panels to re-
duce the transmission of noise and vibration from the
engine compartment to the passenger compartment.
A foam asphalt sheet provides a good contact surface
with steel panels. This increases the dampening effect .
2) Silencers over the floor area
Silencers minimize the transmission of noise/vibration
into the passenger compartment.
An asphalt sheet covered with a resin layer is located on
the floors in the spare tire stowage and front passenger
seat, significantly reducing the transmission of noise
and vibration .
