Acoustic energy and the ratio that incides the total acoustic energy on material that material absorbs, be sound absorption coefficient (α).
α=Eα/Ei=（Ei-Er）/Ei=1-r
In formula: Ei---incident acoustic energy;
E α---by the acoustic energy of material or structure absorption;
Er---by the acoustic energy of material or structure reflection;
R---reflectance factor.
When incident acoustic energy is by complete reflex time, α=0, indicates without sound absorption; When incident acoustic wave is not reflected completely, α=1, represents to be absorbed completely.
The sound absorption coefficient of general material or structure is α=0-1, and α value is larger, represents that sound absorption can be better, and it is to characterize at present the most frequently used parameter of sound absorbing capabilities.
The sound-absorption coefficient of sound-absorbing recombiner unit plate described in the utility model (as the D in Fig. 5) contrasts with the sound-absorption coefficient (as the C in Fig. 5) of common abatvoix, the sound-absorbing effect that can find out sound-absorbing recombiner unit plate described in the utility model obviously will be higher than common abatvoix, and sound-absorbing frequency extends to high hertz frequency range.
