The invention relates to an acoustically effective wheel house covering
for vehicles, i.e. a wheel house covering which can reduce transmission
of splash water noises in the passenger compartment of the vehicle and
which can absorb the sound of rolling tires on a roadway, which wheel
house covering comprises several layers of material. In order to improve
the sound-absorbing effect of such wheel house coverings, it is proposed
that the wheel house covering is formed of at least three air-permeable
sandwiched layers of material (6, 9, 10) comprising a first textile
material layer (6) facing the wheel housing, with the air permeability of
said first textile material layer at a test pressure of 1 mbar ranging
from 15 to 60 l/m.sup.2s, and with the air permeability of a second
textile material layer (10) arranged between the first (6) and third (9)
material layers at a test pressure of 1 mbar ranging from 100 to 1500
l/m.sup.2s, wherein the third material layer (9) is a textile material
layer facing the tire, with the air permeability of said third material
layer at a test pressure of 1 mbar ranging from 20 to 200 l/m.sup.2s.
