1、毕业论文外文翻译Audio appearance and connotationLook sound more attractive to consumers, which in fact is a very normal thing, like a good-looking young woman can always first causes the mans interest. In the face of an ordinary appearance, but has a good connotation woman, men often could not understand he

2、r meaning, may have been another is more beautiful and later moved, rush into the embrace of beauty . . If the other person but the soul is not the United States , the man also only regret you down. But the general connotation of appearance, first-class woman, but also lost an opportunity. In this c

3、ase, there seems to be no winner. Life is like this, so is selling audio.For most non fancier of ordinary consumers, it is difficult to understand what is the beauty of music, what is the sound of beauty, but also no time, no interest to understand these things, so they are unable to establish and f

4、ancier as sound values. Have a fever for a piece of equipment, they will feel it sounds better, or to such a voice pay a higher price. The general consumers can grasp, only the appearance of the sound design such representation element. They would like to buy the furniture, see this sound like equip

5、ment is pretty, put in the home can reflect the owners of wealth and taste, the sound of the attribute of voice - but to pay too little attention. In a word, the ordinary consumer is the appearance of virtue to judge the sound value, rather than by the sound.Therefore, many engage in store person se

6、ized this point, the products get pretty, though it is but a group. Plus fashion stores in the design, a sham theory and concept ( can only deceive the unqualified ), and be trained with regularity marketing practices, the average consumer coax ass bounced to the audio to buy back. Be honest, actual

7、ly this kind of practice is not much criticized, because it is the most direct, most impressed general effective method. Fancier dissatisfaction is nothing more than scolding some treasures outside its sell the stuff is too expensive, even with the real Hi-End equipment is not far, is out and out ac

8、ts of violence!So, this kind of pure rely on sell product hue approach will always be successful, I can not. I remember one of my relatives due to the pursuit of style, in a store to buy a ten thousand yuan package machine. Buy back very excited, and publicity. Who knows and colleagues that set of60

9、00 yuan from HI-FI ratio, set machine sound is only a rotten words can describe! I like the relatives of a head-on blow, so that more than 10000 yuan package machine shut up, the right to display. Now, the consumer sense of loss is great, but those who earned a quick money store and how? The brand i

10、mage is also enough to be fatal injuries! But come to think of it, and felt that I was too to entertain imaginary or groundless fears, because this kind of monopoly treasures outside its stuff, you may not want to do their own brand names for a long time, do a good job! I think, as long as there is

11、a true Hi-Fi industry exists, with relevant manufacturers, businesses, media efforts, consumers can compare opportunity, know what is good audio.Of course, really do have a fever equipment manufacturers are also worth reviewing. In very long period of time, manufacturers often have wine is not afrai

12、d of alley deep wrong idea, rather do you like my voice would have to accept my fault domineering, without careful attention to the actual needs of consumers. Design too traditional, too professional, and life, home furnishing, the publics aesthetic from more and more far, coupled with the lack of e

13、ffective promotion, led to the general consumer Hi-Fi sound generating a sense of mystery and the sense of distance, think Hi-Fi equipment is designed for those brain burn abnormal offbeat used, and their it doesnt matter is essential. If we have a fever manufacturers to ignore this fact exist, only

14、 for its own narrower.Sound effects and create the stage atmosphere coordinationAbstract: the stage atmosphere is a comprehensive art, the art of sound stage is a important and integral part of the. No high quality sound stage art do safeguard without success to show the stage atmosphere. However, t

15、here is also the stage atmosphere stage sound and advance the development of the product, at present the two interdependent, reciprocal causation. Based on years of practical work, summed up the sound effects and create the stage atmosphere to coordinate a few experience.Key words: sound effects, th

16、e stage atmosphere, coordinationOne, forewordWhether sufficient understanding and play sound effects on stage atmosphere coordinating role, to the stage atmosphere overall effect, in the past, people tend to neglect the sound effects in the stage atmosphere in the role, but take it as a mouthpiece,

17、amplifier and so on. No see of its own with the comprehensive function, regulation, conduction function and value. As the stage the rapid development of science and technology, a group that has times sex, scientific sex and artistic sound effects of the impact of the stage, the stage sound effects i

18、n the atmosphere effect also is shown ceaselessly come out. Therefore, we have to sound effect in the stage atmosphere in rats given full recognition. And in theory to prove, the prosperity of literature and art, meet peoples multi-level aesthetic demand, have very important sense.Two, theory connot

19、ation( a ) the stage atmosphereCreate the stage atmosphere is through artistic means in the arena of reproducing state of life, and the life scene and atmosphere environment. The sound effects are available through this stage platform embody various carrier atmosphere, for performing Zengguang luste

20、r, color brightness, so that the situation be better show stage.( two) the stage sound effectWhat is the effect of a stage performance, designed for use with the atmosphere of the show the design, configuration of the various audio, referred to as effect. Sound effects can be divided into the sound

21、source sound effects and audio sound effects two categories. A sound source sound effects may also be referred to as the reality effect. No sound source sound effects and can be referred to as unrealistic effect.In three, the sound effect of coordination functionSound effect coordinating role is to

22、grasp the stage sound overall image key link, the sound stage with high and low, fast, slow, only through sound effects coordination function, can make the different quality of the image, coordinated into a unified, coordinated, match. Its role in relation to each stage atmosphere of the show is to

23、successfully, this requires the audio division to grasp the function and performance of device use, under different conditions, either acoustic or the instrument, whether close talking microphone, or a capacitor microphone, in this model each one, with source different locations and different receiv

24、ing frequency and so on, the received audio signal is different. In this way, only through sound effects coordinating role, to make the sound emitted music be lively and vivid, euphemism sweet, melodic, let a person have the feeling of be personally on the scene. Its role not only on the sound stage

25、 component coordination, at the same time, also will be the sound stage image between the audience and the coordination, only the relationship between the three well coordinated, can produce the artistic resonance.Four, sound effects and create the stage atmosphere harmonious countermeasureSound and

26、 audio spatial relations importanceAn acoustic space, each have different characteristics of soundEvery sound space like every person, will have their different characteristics of sound. People would because of vocal fold structure, pleural cavity resonance and produce different sounds different. Si

27、milarly, every sound space also because of different size, proportion, interior decorating and have their own unique sound characteristics. In other words, there is little two sound is the same: the same, rarely two stereo sound as space.Based on the above cognition, audio enthusiasts can know, even

28、 using exactly the same audio equipment, as long as the sound space is different, will produce a different sound characteristics. These different characteristics of sound like different music hall, as long as it is a successful music hall, will have their own charm charming voice. The same, as long

29、as the successful acoustic space, also have their own charm charming voice. Usually, the success of the acoustic space as a successful music hall, is hard to find. You must be careful plan to construct a music hall or the acoustic space, but this does not guarantee that you can certainly obtain char

30、ming sound Two, rational audiophile should own exclusive to a minimumEvery audiophile, inevitably because of long-term in their sound in the space, and is adapted to generate their own audio spatial hearing music habits and preferences. At the same time, also very naturally to their own masters musi

31、c habits and preferences as a benchmark to judge others, the acoustic space and others listen to music habits, preference. When you own sound space characteristics of sound, listen to music habits and preference for the standard, to others do negative judgment, dont forget, others also can use such

32、a foothold on you do negative judgement. Therefore, when you hear is different from her own sound, the first thing to do is not the exclusive claims arise spontaneously, but reflection. Through reflection, try to find the others sound beauty department.In three, the acoustic space sound effects with

33、 live music as the standard, this standard is not the onlyWhat sound space sound effects will have a standard? If not, not public opinions are divergent., unable to agree on which is right? Of course there is a sound effect is good, but please note, the quality standard is not the only one, but mult

34、iple. Sound effect is good in there? In live music playing effect. Any canned juice drink up like the original fruit, must be with the fresh fruit flavor as the standard to judge. Similarly, any music software playback sound effect is good, also must with live music performance as a criterion to jud

35、ge.However, live music and sound effects of beauty is not the only one, but multiple. Classical music is concerned, there are many recognized outstanding concert hall acoustics, they each have different characteristics of sound. Some some some warm, full, clear transparent, some low frequency rich,

36、some voices close high ( sounds surrounding feeling good, musical instruments like close to you ). In any case, the music hall of the sound characteristics of the United states.In the audiophiles home, because after the unknown recording site characteristics of sound, recording equipment characteris

37、tics of sound, playback audio equipment sound characteristics, and the audio sounds of space characteristics of four heavy influence, make the audiophile simply does not have the qualifications to discuss whose sound effects really. Audiophile can exert is discussed, whose sound effects of the Unite

38、d states. And the beauty of the standard is to live music performance as the standard, but also multiple beauty, multiple criteria.In four, soft than hard tone space spaceWhat is soft space? Floor, walls, ceiling to splint or plaster or wooden, is soft space. What is hard tone space? The ceiling, fl

39、oor and walls with reinforced concrete 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.Why soft space than hard tone space? Because of hard tone space cannot be adequ

40、ate absorption of excessive high frequency and low frequency, high frequency caused by listening to music is too harsh or too low frequency band compression. Whether soft adjustable space is no disadvantage? No. Soft space may also exist in low frequency section absorbs excess generation of low-freq

41、uency, not strong enough. However, compared those two, soft space is relatively suitable for listening to music.Five, how to put hard tone space into a soft spaceTaiwan homes are built with reinforced concrete or dwelling house Residence, if will be hard adjustable space is transformed into a soft s

42、pace, 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 does not use up too much of the interlayer space, also can be a layer of insulation effect.Gypsum board than the wooden core board. Pe

43、rhaps you will ask, why not a wooden core board or thin plywood 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 avoid using thin

44、 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 influence is relatively small. Furthermore, gypsum board is fireproof material, home use it to do the sandwich will be safe. Here, I provide a g

45、ypsum board with several absorption rate splint for your reference : the same is the9mm board thickness, air layer thickness of about 45mm, gypsum board in the125Hz absorption rate is 0.26, can absorb some of the standing waves. While the splint absorption rate of only 0.11. In250Hz, gypsum board, s

46、ound-absorbing rate was reduced, only 0.13. To the 500Hz absorption rate is lower, only 0.08. On the contrary, the splint in the 250Hz, absorption rate is high up to 0.23. If the splint reduces the thickness of6mm, in the250Hz sound-absorbing higher rates of up to 0.33. From the above absorption rat

47、e, you should understand why I would recommend the use of gypsum board.As for the ceiling and 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. Us

48、ually, the general 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 space of similar size. This carpet is the role of the absorption o

49、f some from the horn to the floor, and shoot the reflections from the ceiling to floor acoustic. Usually, the carpet will only on intermediate frequency than the frequency of effective, for low frequency, low frequency is no absorption effect. However, because of its absorption of the medium frequen

50、cy than the frequency, so they changed the human ear for mid frequencies below the sense of listening, so it sounds like a whole will change the general.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 r

51、ole mainly in 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 a concave shape, do more convex shape or an arc. Because concave w

52、ill make the sound of poly somewhere, and the convex shape or arc shape can be diffusion wave. Another point to note, the ceiling modelling is best not to one whole piece together, this practice will make its absorption frequency range lower, affected the band s full. The correct approach should be

53、the ceiling partition into several areas, with each area are not connected with each other the principle to design modeling.In six, hard modulation soft, space surface should be how to deal withThe stereo space by a hard switch for soft, then in accordance with the Liu Shihao sound song principle, w

54、ith before the hard suction after diffusion methods to do surface treatment.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 practices will absorb the horn emitted acoust

55、ic 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 rear wall of the reflection, combined into a strong enough voice.This will have a question? The front is said to nail plas

56、terboard walls become soft space? So do not now required by the hard 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 not nail, nail ( als

57、o can avoid windows to nail, dont be windows sealed, so to light and air. ) The above two situations can make the rear wall is maintained in the hard tone of the state.Comparative need to consider is the horn back wall is a wall, whether or not the nail gypsum board? If you expand the power of machi

58、ne is not big, the horn is not too big, I recommend this wall dont nail plasterboard. Conversely, can be nailed together.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 rel

59、atively thick, 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 not violate the principle of hard.The side walls to absorb. The s

60、o-called suck, is the horn and the listening position between the two side wall to make the sound absorbing 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 stro

61、ng too, to direct sound interference, effect of positioning are clear. In addition, because the first reflection of excessive, will cause high frequency above the ears of the people of the pressure, the most direct feeling is too bright too harsh voice.Common many audiophile in this section of the t

62、wo side wall 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 want to use the two remainder diffusion plate, you should use the surfa

63、ce of thick cloth soft diffusion plate, in addition to its diffusion effect, also on the high frequency section has absorption effect.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,

64、also can hang some soft materials, 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 just wasting money. If you want to in the two side wall so

65、und-absorbing material, at least as Terry such material is effective.As far as I know, the most inexpensive and efficient material is glass fiber cotton. With the thickness of 5cm, 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 ( dont bare ), as imaging frame general. This is the effect of very good two side wall first reflection absorber.The listening position back diffusion. What is the diffusion? The so-called diffusion from the listening position to the r
