Millennium Metal takes the spaced absorber principle one step further. The metal panel is micro cracked to create the ideal airflow resistance to optimally absorb the sound impinging on it. The low frequency absorption can be enhanced by increasing the air space behind it.
Embossed faced foam is a high performance acoustical material with superior absorption at the most critical frequency bands. It is often used in speaker housings, medical equipment, HVAC units, blower enclosures, and office equipment such as computer and printer housings.
The need to absorb noise inside a machine enclosure often accompanies the need to damp vibration on the same structure. Where it is not possible to totally enclose a noise source, as in many types of machinery, electrical appliances, office equipment and electronic controls, the inside of the enclosure should be lined with sound absorption material.
Perforated Vinyl Faced Foams combine the absorption properties of acoustical foams with the toughness and durability of vinyl. The perforation pattern has been engineered to provide maximum absorption and resilience with 14% open area. The attractive leather like appearance makes it ideal for vehicle interiors, marine headliners, and enclosures.
Foam Melamine is a lightweight, high temperature resistant, open cell foam manufactured from melamine resin. It combines excellent thermal properties with superior sound absorption capabilities to create a versatile fiber free product which can be applied in situations which may prohibit the use of urethane foams or fiberglass insulations.
dBcloth acoustical foams are designed to provide maximum absorption of airborne sound with minimum thickness and weight. These flexible polyurethane open cell foam products are manufactured to optimize pore size, air flow resistance, and density. Sound energy, passing through the cell structure, is converted into minute quantities of low grade heat that is easily dissipated. Since the uniformity of the cells are carefully controlled the efficiency is constant and predictable from one installation to another.
