VIBRO-ACOUSTIC ATTENUATION AND/OR REDUCED ENERGY TRANSMISSION DEVICE FOR USE IN PASSENGER CABIN OF AIRPLANE TO BLOCK E.G. SOUND TRANSMISSION FROM ENGINE TO PASSENGERS, HAS MECHANICAL RESONATOR CONNECTED TO SIDES OF HOST STRUCTURE
The present invention relates to devices that display frequency zones of strong vibro-acoustic attenuation or reduced energy transmission. This can be used in particular, although not necessarily solely, in applications that require lightweight materials with good mechanical properties and good vibro-acoustic response or in applications that require materials with high sound reflection, absorption or sound isolation in a certain frequency band.
