Material, i.e., very thin sheet metal, such as aluminium foil, maximum gauge are 0.2 millimeter.
It will be understood by those skilled in the art that by taking sound-absorbing material as an example, in the range of certain thickness, noise is inhaled with top
The thickness increase of sound material and reduces, as soon as but after sound-absorbing material thickness reaches maximum, noise does not have to change substantially.
Therefore, we can determine the thickness of acoustic material and height, obtain the maximum by testing, be determined as the suction to be set
Sound material thickness.After this maximum is found, it is believed that noise reduction most short slab has not been air outlet at this time, reattempts increase
The height or thickness of acoustic material, see whether effectively reduce noise, if effectively, illustrating that most short slab at this time has been looked for
Arrive.For most short slab, the height or thickness of the acoustic material for effectively reducing noise are found according to the method identical with sound-absorbing material
The maximum of degree, is determined as the sound-absorbing material thickness to be set.
Thus, in some optional implementations of the present embodiment, the thickness of sound-absorbing material 106, air inlet at air outlet
Place's thickness of sound-absorbing material 106, the height of acoustic material 105 of internal side of shell wall, the thickness of acoustic material 105 can lead to respectively
Following methods are crossed to determine：Select parameter to be determined, wherein, parameter to be determined be the thickness of sound-absorbing material, internal side of shell wall every
Any one in the height of sound material, the thickness of acoustic material；Other specification is defined to fixed value, is changed according to preset rules
The value of parameter to be determined；The noise decrement of correspondence position when detecting the value change of parameter to be determined；In response to noise decrement
Less than predetermined threshold value, parameter to be determined is determined according to the value of previous parameter to be determined.
For example, the thickness of sound-absorbing material 106 keeps air inlet sound-absorbing material as parameter to be determined at selection air outlet
106 thickness, the height of the sound-absorbing material 105 of internal side of shell wall, the thickness of acoustic material 105 are fixed value, according to default rule
Then (such as be incremented by 1 centimetre), the thickness value of sound-absorbing material 106 at air outlet is changed, the thickness of sound-absorbing material 106 at detection air port
Noise decrement (such as decibels than preceding once reduction) when angle value changes at air outlet 104；In response to noise decrement
Less than predetermined threshold value (such as 1 decibel), sound absorber at air outlet is determined according to the thickness value of sound-absorbing material 106 at previous air outlet
The thickness of material 106.For example, 20 centimetres of the thickness value of sound-absorbing material 106 at previous air outlet is determined as inhaling at air outlet
