the graph, below right. Inpractice, the maximum barrier
attenuation cannot be greaterthan the louvre transmission
loss (TL).

We shroud noisy plant and
machinery with special acousticenclosures, build road barriers,
silence air conditioning systemsand combat the noise emissions
of large, powerful gas turbineengines. We install partitions inhotei function rooms and
provide school children with the
special facilities they need to
learn foreign languages and
practice playing their musicalinstruments. And our acoustic
