Abstract

Aluminum Metal foam has mainly of two types, viz. Open cell and Closed cell. There are many applications of aluminum metal foam viz. — Structural applications, Heat exchangers, Cooling machines, Silencers, Acoustic applications, Flame arresters, Corrosion resistant applications. Metallic foams typically retain some physical properties of their base material as the foam is generally recyclable back to its base material.

In this Paper, we have studied sound absorption analysis of aluminum metal foam under different sound intensities and studied damping coefficient of aluminum metal foam. Compared with the Open cell, Closed cell Al foam and Plain Al sheet, the advantage of using metal foam as a sound absorber is obvious, self-supporting due to its rigidness and strength, fire resistance, low moisture absorption and superior impact energy absorption capabilities. It is expected that metal foams will find a wide range of applications in noise and vibration control of aircraft, automobiles, machinery and buildings.
