Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of sound insulating panel, particularly a kind of honeycomb acoustic septum.
Background technology
Sound is a kind of wavy energy, needs medium to propagate.Sound is when same Propagation, and Media density is larger, and spread speed is faster.Spread speed such as in normal temperature air is about 340 meter per seconds, and the spread speed in rail is about 5200 meter per seconds.
It is exactly across Medium Propagation that the another kind of sound is propagated.Namely from a kind of medium, the critical contact face through two media enters another kind of medium, and now, the transmission essence of acoustic energy is the transmission of Oscillation Amplitude.During across Medium Propagation, the density difference of two media is larger, and the loss of acoustic energy is larger.And in practical application, air is activity space under mankind's normality, so the material differing larger with atmospheric density is generally the very high material of density (material also more much lower than atmospheric density is except vacuum, also genuine few), namely can be considered sound insulation materials.Density is higher, and soundproof effect is better.The sheet material that such material is made, is called sound insulating panel.
The sound of the not all frequency of sound insulating panel can intercept, and object has natural reonant frequency, and close to the sound of object resonance frequency, the soundproof effect of sound insulating panel significantly reduces.
Sound insulating panel has the difference every air borne sound and chatter.Air borne sound sound insulating panel, what namely intercept is the sheet material of the sound propagated in atmosphere.The sheet material of the sound that what namely chatter sound insulating panel intercepted is propagates in stiffening member (as steel concrete monolithic house) and system.
Its publication number of Chinese patent CN204547236U discloses a kind of composite sound insulation board, comprise outer surface layer (1), interior surface layers (6) and sound-absorbing material layer (2), be wherein provided with sound-absorbing material layer (2), sound insulating panel one (3), sound insulating panel two (4) and fire protection flame retarding layer (5) between outer surface layer (1) and interior surface layers (6) successively; Between outer surface layer (1) and sound insulating panel one (3), between sound insulating panel one (3) and sound insulating panel two (4), between sound insulating panel two (4) and fire protection flame retarding layer (5), be all respectively equipped with sound-absorbing material layer (2); Sound insulating panel two (4) is double-decker.
Can find out, the sound insulating panel of above-mentioned patent is compared with the sound insulating panel of prior art, and soundproof effect improves 10%-20%.But it not only comprises sound insulating panel one, sound insulating panel two and sound-absorbing material layer, also comprises fire protection flame retarding layer, therefore, its complicated structure, cost compare is high.
