INTERNATIONAL COOPERATION IN
THE FIELD OF ACOUSTIC INSULATION
Metamaterials for acoustic insulation represent another
area of research, being explored in the ›NAIMMTA‹ research
project. The advantage of these innovative, lightweight
foams and glass wool bundles, installed between the primary
structure and the lining, is that they provide acoustic
insulation in specific frequency ranges while significantly
reducing weight. Relatively heavy insulation is currently
used to block engine noise in the cabin. This research
project is being conducted by ZAL GmbH as project lead,
in collaboration with Airbus, Hutchinson, Hamburg University
of Applied Sciences, and international partners from
Canada – NRCC, 3M, Mecanum, University Sherbrooke and
Montreal′s École de Technologie Supérieure.
