Acoustical performances of Metafoam's material are outstanding, especially in low frequencies. Actually, no other metal foam, polymer foam or mineral fibers offer similar performances.
Metafoam's material shows great acoustical properties and has many other advantages over polymer and mineral foams:
stiffer;
more durable;
resists to high temperatures and humidity;
absorbs energy.
