SOUND ABSORPTION DESCRIPTION: INTRODUCTION SOUND ABSORBING TREATMENT FIBROUS MATERIALS PANEL RESONATORS HELMHOLTZ RESONATORS TRANSONDENT FACINGS TEST MOUNTINGS APPLICATIONS DESCRIPTION: BUILT WITH A MEMBRANE SUCH AS PLYWOOD IN FRONT OF A SEALED AIR SPACE . THE PANEL IS SET IN MOTION BY THE ALTERNATING PRESSURE OF THE IMPINGING SOUND WAVE. THE SOUND WAVE IS CONVERTED INTO HEAT THROUGH INTERNAL VISCOUS DAMPING. PANEL RESONATORS

SOUND ABSORPTION APPLICATION: INTRODUCTION SOUND ABSORBING TREATMENT FIBROUS MATERIALS PANEL RESONATORS HELMHOLTZ RESONATORS TRANSONDENT FACINGS TEST MOUNTINGS APPLICATIONS APPLICATION: USED WHERE EFFICIENT LOW-FREQUENCY ABSORPTION IS REQUIRED AND MIDDLE- AND HIGH-FREQUENCY ABSORPTION IS UNWANTED OR PROVIDED BY ANOTHER TREATMENT. PANEL RESONATORS
SOUND ABSORPTION DESCRIPTION: INTRODUCTION SOUND ABSORBING TREATMENT FIBROUS MATERIALS PANEL RESONATORS HELMHOLTZ RESONATORS TRANSONDENT FACINGS TEST MOUNTINGS APPLICATIONS DESCRIPTION: AIR CAVITY WITHIN A MASSIVE ENCLOSURE, CONNECTED TO THE SURROUNDINGS BY A NARROW NECK OPENING. HELMHOLTZ RESONATORS
SOUND ABSORPTION METHOD OF ABSORPTION: INTRODUCTION SOUND ABSORBING TREATMENT FIBROUS MATERIALS PANEL RESONATORS HELMHOLTZ RESONATORS TRANSONDENT FACINGS TEST MOUNTINGS APPLICATIONS METHOD OF ABSORPTION: THE IMPINGING SOUND CAUSES THE AIR IN THE NECK TO VIBRATE & THE MASS BEHIND CAUSES THE ENTIRE CONSTRUCTION TO RESONATE AT A PARTICULAR FREQUENCY. AT THAT FREQUENCY ABSORPTION IS VERY HIGH & DROPS SHARPLY ABOVE AND BELOW THIS FREQUENCY. HELMHOLTZ RESONATOR
