But, the sound proof window that current sound proof window is airtight often, intercept noise by time simultaneously also intercept passing through of air, people live in atmosphere draught-free, the environment that do not exchange, can in generating chamber air oxygen reduce, the phenomenon of air quality difference.Of long duration will to have an impact to the healthy of people.New wind with reference to the 6.6.1 workplace of " Design of Industrial Enterprises sanitary standard " basic hygienic requirements in GBZ 1-2010 the 6th chapter workplace should from outdoor, fresh wind port should be arranged on air cleaner district, resh air requirement should meet following requirements: non-air-conditioning workplace accounts for the workshop of volume < 20m3 per capita, should ensure the amount of fresh air per person >=30m3/h; During as shared volume > 20m3, the amount of fresh air per person >=20m3/h should be ensured; Adopt the workshop of air conditioning, the amount of fresh air per person >=30m3/h(0.008m3/s should be ensured).
If use blower fan dispatch wind, it is the problem that can solve room air circulation, exchange.But blower fan can produce extra noise, the maintenance expense of extra energy consumption and blower fan also can be produced.
Labyrinth silencer also claims cell-type sound absorber, and be together in series several cell-type sound absorbers formation labyrinth silencer.This sound absorber except there is resistive effect, by the expansion of cell section with reduce, also have resistance effect, therefore, be characterized in anechoic frequency bandwidth, sound deadening capacity is higher, but resistance is damaged comparatively large, is applicable to low wind friction velocity, and wind speed υ is unsuitable >=5m/s.
The aerodynamic quality of sound absorber evaluates another important indicator of acoustic attenuation performance, it reflects the size of sound absorber to gas-flow resistance.The aerodynamic quality of sound absorber represents with resistance coefficient or drag losses.Drag losses, is called for short resistance and damages, when referring to air-flow by sound absorber, at the numerical value that the hydrostatic pressure of muffler outlet end reduces than entrance point.
The loss of total pressure △ P of sound absorber, comprises and calculates △ Pj along stroke pressure loss △ Pm and local pressure loss,
△P=△Pm+△Pj(Pa) △Pm = λ/de×υ2/2×ρ △Pj= ξυ2/2×ρ(Pa)，
△P=λ/de×υ2/2×ρ+ξυ2/2×ρ=(λ/de+ξ)υ2/2×ρ
In formula: the Δ P--pressure loss, Pa;
λ--coefficient of frictional resistance;
The effective silencing channel equivalent diameter de=2ab/a+b of de--sound absorber
υ--wind speed (m/s)
ξ--coefficient of partial resistance
ρ--atmospheric density (generally getting 1.2kg/m3)
Obviously, size is damaged in the resistance of sound absorber is have directly related with the air velocity size under service condition.As air velocity υ≤0.30m/s, gross pressure pressure loss Δ P≤0.054 (λ/de+ ξ) (Pa) of sound absorber.
