摘要

The acoustic insulation complex includes the bulkhead wall (15) to be insulated and an acoustic absorbing material (16) which is placed along this wall. The complex comprises a material (17) of low Young's Modulus such as elastomer or bitumen which is intimately connected to the wall. An Independent claim is included for a method of obtaining the complex.
