The market for sound insulation products and services, accounting for
some 6 000 mill. DM per annum in Germany alone, is covered to the exte
nt of more than 90% by developments which are over 40 years old. Exper
ts at the Fraunhofer Institute for Building Physics (IBP) (Director: P
rof. Dr. Dr. h. c. mult. Dr. E. h. mult. K. Gerris) have, together wit
h an increasing number of small to medium-sized licensees, concentrate
d on the development of alternative, fibre-free absorbers (ALFA). The
aim is to thus reduce noise pollution with more efficient sound-proofi
ng technologies even in cases where traditional sound insulation mater
ials are at a disadvantage as regards fitting and durability.
