NOISE INSULATION

MORE THAN 45 YEARS OF EXPERIENCE Since 1969 AMC MECANOCAUCHO® have been designing and manufacturing products for the attenuation of structural borne noise and vibration for a wide range of Industry. In 1990, to compliment the structural borne aspect, AMC began to design and manufacture a range of AKUSTIKABSORBER® composites to attenuate Airborne noise.

QUALITY COMMITMENT Only the very highest quality raw materials go into the manufacture of AMCMECANOCAUCHO® manufactures high quality products, with state of the art machinery, to produce these effective, high quality composites.

1. APPLICATIONS ANDINSTALLATION GUIDE Akustikabsorber products are materials designed to reduce reverberation and increase the attenuation between chambers. AMC MECANOCAUCHO® provides customers with its vast experience and know how in a wide variety of applications and installations. Examples of different cabin executions to reduce noise emission to the exterior while maintaining proper ventilation.

2. ACOUSTIC CHARACTERISTICS: KUNDT’S TUBE Kundt’s tube measures transmission and absorption of a normal perpendicular impact wave. “If we compare the measurements attained in a reverberating or transmission chamber, the results will always be poorer in Kundt’s tube, since all the waves produced in the tube are direct impacts”. Transmission Loss (dB) TL(dB) Kundts Tube is very sophisticated standardized test equipment, behaviour in the absorbtion and isolation against a range of frequencies. Absorption coefficient Development of new products: Knowing our client’s specific needs, we develop new...

3. MEASUREMENTS To effectively treat noise problems the rasnge of frequencies and sound levels must be identified. With that detailed information calculations can then be carried out to determine the best method and type of composite. AMC MECANOCAUCHO® applies its experience and know how in measuring and evaluating customers problems to successfully treat their applications by reducing machine produced noise and vibration emmissions.

GENERAL CATALOGUE ACOUSTIC KNOWLEDGE NOISE THERMOMETER Reverberation time: The reverberation phenomenon is produced as a consequence of the consecutive bouncing of the sound wave on the walls of an enclosure. The reverberation time is the length of time needed for a sound pressure to decay 60dB in the enclosure or Basic concepts of acoustics within Industry: When calculating or designing the isolation of a room or a vehicle cabin the following concepts are important absorbent materials to reduce the emission evels of the room, by absorbing part of the nterior walls' reflections, the level within...
