43、, soft than hard tone space space</p><p>　　What is soft space? Floor, walls, ceiling to splint or plaster or wooden, is soft space. What is hard tone space? The ceiling, floor and walls with reinforced concr

44、ete or brick space, called hard tone space. Most of the living environment of Taiwan are hard tone space; and most of Europe and the United States, Japan living space are the soft space.</p><p>　　Why soft sp

45、ace than hard tone space? Because of hard tone space cannot be adequate absorption of excessive high frequency and low frequency, high frequency caused by listening to music is too harsh or too low frequency band compres

46、sion. Whether soft adjustable space is no disadvantage? No. Soft space may also exist in low frequency section absorbs excess generation of low-frequency, not strong enough. However, compared those two, soft space is rel

47、atively suitable for listening to music.</p><p>　　Five, how to put hard tone space into a soft space</p><p>　　Taiwan homes are built with reinforced concrete or dwelling house Residence, if will

48、 be hard adjustable space is transformed into a soft space, first start is four walls. The walls can ask carpentry master the use of gypsum board nailed a sandwich, sandwich shop in the glass fiber cotton. This approach

49、does not use up too much of the interlayer space, also can be a layer of insulation effect.</p><p>　　Gypsum board than the wooden core board. Perhaps you will ask, why not a wooden core board or thin plywood

50、 to nail the dissection, and to the use of gypsum board or plywood? Because the thin plywood or wooden core board easily absorbed in the frequency band, and listen to music when the band full is very important, so we can

51、 avoid using thin plywood or wooden core board. While the gypsum board because quality is heavier, the absorption of low frequency more, for we listen to music and negative i</p><p>　　As for the ceiling and

52、floor of the practice, and their practice has different walls. First floor. Taiwan due to the humid climate, use less appropriate carpet. Otherwise, the floor space is also thick carpet softening method. Usually, the gen

53、eral home floor was tiled or nail with a layer of solid wood flooring. You can in this floor upper berth of a thick wool carpets, carpet is preferably sized approximately with the horn to the listening position this one

54、space of similar size. This carpet is</p><p>　　Mineral fiber board cheap easy to use. Come when it comes to the ceiling, the cheapest way is the light steel frame with mineral fiber board. Its role mainly in

55、 the proper absorption frequency above the band, for if the band did not affect. If you think the mineral fiber plate is not nice, can also please do carpentry with thin plywood ceiling molding. Please note that to avoid

56、 a concave shape, do more convex shape or an arc. Because concave will make the sound of poly somewhere, and the convex </p><p>　　In six, hard modulation soft, space surface should be how to deal with</p&

58、ent.</p><p>　　Horn back wall to hard. The so-called" hard" refers to the first room ( also is the horn back wall and horn between the ) best to do not do too much absorption device, because such pr

59、actices will absorb the horn emitted acoustic energy, makes the extension machine must have a larger power output we can feel the sound is strong enough. If the wall is hard, we only need a smaller expansion machine, the

60、 rear wall of the reflection, combined into a strong enough voice.</p><p>　　This will have a question? The front is said to nail plasterboard walls become soft space? So do not now required by the" hard

61、" contradictory? Whether the conflict according to the actual situation to judge, if horn back wall just is a French window, of course not nail plasterboard. If the horn back wall is half window, gypsum board can no

62、t nail, nail ( also can avoid windows to nail, don't be windows sealed, so to light and air. ) The above two situations can make the rear wall is maintained in</p><p>　　Comparative need to consider is th

63、e horn back wall is a wall, whether or not the nail gypsum board? If you expand the power of machine is not big, the horn is not too big, I recommend this wall don't nail plasterboard. Conversely, can be nailed toget

64、her.</p><p>　　The way. If you listen to music, has been in the two side wall sound-absorbing treatment, or feel that sound too sharp too forward, this time must be in horn back wall hangs a relatively thick,

65、 with the absorption of high frequency characteristics of the material. Such practices will absorb only in high frequency band above the frequency band, the following will not have a negative impact on. Therefore it does

66、 not violate the principle of" hard".</p><p>　　The side walls to absorb. The so-called" suck", is the horn and the listening position between the two side wall to make the sound absorbing

67、 surface treatment. Why this section of the two side wall to sound? Because this area is the sound from the loudspeaker, the first reflective tone source. While the first reflection if too strong too, to direct sound int

68、erference, effect of positioning are clear. In addition, because the first reflection of excessive, will cause high frequency above the ears</p><p>　　Common many audiophile in this section of the two side wa

69、ll placed wood or poly two remainder diffusion plate, this is the wrong approach. Because the wood or styrofoam diffusion plate does not contribute to the first reflection absorption, they only diffusion effect. If you w

70、ant to use the two remainder diffusion plate, you should use the surface of thick cloth soft diffusion plate, in addition to its diffusion effect, also on the high frequency section has absorption effect.</p><

71、p>　　The" suck" for many individuals, subtly different. Smart can be combined with interior decorating, made a kind of aesthetic feeling. If you want to keep things simple, also can hang some soft materials,

72、the same can be achieved to" suck " requirement. Here to remind the reader, general curtain cloth to absorb not a big role, because they are too thin, and most are not high in fiber and soft materials, you are

73、just wasting money. If you want to in the two side wall sound-absorbing material, at le</p><p>　　As far as I know, the most inexpensive and efficient material is glass fiber cotton. With the thickness of 5cm

74、, weight of 20kilograms per cubic meter of glass fiber as an example, it is more than 500Hz frequency is high up to 0.85absorption rate. You can use glass fiber cotton box, wrapped up ( don't bare ), as imaging frame

75、 general. This is the effect of very good two side wall first reflection absorber.</p><p>　　The listening position back diffusion. What is the" diffusion"? The so-called diffusion from the listenin

76、g position to the rear wall of the area to be diffusion. In recent years, we all know that the two remainder diffusion plate is a very good diffusion tools, however, did not know that the use of the diffusion plate numbe

77、rs are enough to be effective. Common situation is just put a diffusion plate there, it will only produce psychological comfort effect, and can not do enough diffusion effect.</p><p>　　Perhaps you will ask,

78、how diffusion benefits in there? If the wave can be uniform diffusion theory in listening area, you all hear acoustic reflection is very average, your listening position is not limited to only one" emperor". Fu

79、rthermore, acoustic wave in acoustic space within the homogeneous diffusion, obvious will improve tone quality, as well as the level of sense, the sense of depth and other" stereo twenty" performance.</p>

80、<p>　　Here to remind readers of two things: first, not only the two remainder diffusion equipment with diffusion acoustic effect, any inclined plane, convex surface or an arc will be diffusing acoustic wave effect

81、. Only two times the remainder by diffusion frequency range is wide. So, in your sound space, you can with a variety of shapes to achieve diffusion acoustic requirements. Second, if you do a variety of processing, still

82、feel that the voice is too sharp, at this time, the listening position be</p><p>　　Seven, reflection, absorption and diffusion of three must be skillfully</p><p>　　Above the" hard suction a

83、fter diffusion" principle, in fact it is audio space" reflection"," sucks" and" diffusion" three kinds of surface treatment principles. These three kinds of methods must be flexible, an

84、d as far as possible in principle under the scope of play to your imagination. I want to remind you, when you want to imitate others processing mode, you must first carefully evaluate, their sound space sound characteris

85、tics, conditions and itself and whether the same with others. Otherwis</p><p>　　Please remember, we elaborate the deployment of reflection, absorption and diffusion acoustic, as is to be" warm",&qu

86、ot; full"," soft"," rich"," clear"," transparent". If you hear is sharp, sharp, thin, white noise, then listen to music will become bitter trials, rather than the easy and ple

87、asant to enjoy.</p><p>　　Eight, two times the remainder diffuser is very easy to use</p><p>　　In two the remainder of said before, said that the first diffusion. The so-called diffusion is the h

88、orn sound from that direction into a reflector, the sound will be uniform in all directions to reflection. So, diffusion can be said to be no point to the. While general acoustic reflection? Is usually oriented. Such as

89、the use of an inclined plane to acoustic reflection. In theory, as long as it is a reflective surface length greater than the acoustic wavelength, then all wavelengths than a refle</p><p>　　From the above de

90、scription, you can understand, in audiophile stereo space, we need to be spread, rather than directional reflection. Because the diffusion can make indoor acoustic more uniform, and the orienting reflex will only on a lo

91、cal reach an influence. Again, what is the two numbers? It is the English quadratic residue. The name comes from the formula HN = ( lambda0 / 2n )? Sn, Sn is to n square divided by N remainder. Type0is to spread in excit

92、ation wavelength of the center frequency ( </p><p>　　Benefit is the diffusion range is very wide. In fact, tells the readers the two remainder diffusion of simple formula, may help you to understand the soun

93、d diffusion, our main purpose is to let you know the origin of the term. In this theory as a basis for many types of the diffuser, which specifically diffusion, diffusion and absorption is two and, more diffusion, absorp

94、tion and reflection of the three combination. In addition, except for the wall, also used for ceiling.</p><p>　　Why the two residue diffuser in recent times welcome? Because it has a diffusion properties: if

95、 the center frequency is accurate, its diffusion range lower limit can be extended downwardly to the center frequency of about half an octave below ( if the center frequency of 1000Hz, half octave is 750hz ), the cap is

96、very high, can reach the center frequency ( n-1) times. Assuming that the center frequency of 1000Hz, the two residue diffuser step7, then spread the upper limit of the range of about60</p><p>　　See here, I

97、think you already know, the general had seen outside the two residue diffuser are almost all aimed at intermediate frequencies above; and step number (here refers to the step number is a single group number, rather than

98、the two group of three groups combined ), diffusion frequency limit is higher also. In addition, why no one will do three, five steps? Because of its relatively low diffusion limit.</p><p>　　Nine, greater sp

99、ace than the small space</p><p>　　Why big space than small space? The reason is very simple, because of the large space volume is larger, the horn out of the acoustic boundary ( six walls ) degree of distort

100、ion is relatively small, you get the sound will be more correct. This is why if we use computer software to do speaker test, usually required in larger space measurement. Because sound less boundary interference distorti
