Sound Words

A picture wins a thousand words. Unfortunately, no picture can tell us how to sound clearly, so it is necessary to use words to describe it. But if you want to make the concise phrases vivid and cause some resonance, you will have to go into details first. Otherwise, you will not know half a day. line array

Here are some of the frequently used adjectives and terms:

1 * resolution

Anyone who has played a camera knows that good shots can produce clear, layered pictures. Sound equipment from the start to the horn system, no one does not affect the resolution, even the signal line and the horn line are no exception, even the end of the clean and good contact or bad contact. Like the photo, the resolution is the sense of hierarchy. There is a sense of depth in a sense of depth; the landscape is far and near at a glance, and the sense of sound on the sound is far and close to the sound - we call it a three degree sense of space. But on the sound, we usually say that the resolution is much more than half the "1" string, the "2" sound "3" ensemble instruments are clear and equal to each other.

2 * three degree space sense

The sense of space is three degrees. Unfortunately, in stereo, "stereo" is mostly narrowly defined as the difference between the sound emitted by the left and right speakers. If there is, most people will say that there is a three-dimensional sense, and few people notice whether the so-called three dimensional sense of depth is also felt after the so-called three-dimensional feeling. That's why a lot of people ignore the importance of horns, put their trumpets on the wall, and pay attention to the separation of the sound from the center to the left and the right, and ignore the distance of the sound. Of course, this is not to say that the sticking wall is not good, but rather depends on the characteristics of the horn.

In addition, the timbre of the three dimensional space is also the location of the loudspeaker. Hearing is not difficult to distinguish the distant position of the sound body. Therefore, if the soprano is slightly weaker, the Alto is slightly stronger, or the pitch time is slower than that of the Alto, people will feel the high pitch and the middle pitch far and near. If the tweeter is strong, we will feel that the sound is flat. In short, if the pitch and pitch are equal or equal speed, the sound will be planar.

Is it possible to form a three dimensional sense of pitch if the pitch is weak? In principle, however, if it is weak and affects the resolution of the tweeter, the resolution will be poor. So it is necessary to give consideration to each other.

3 * * a smooth response

The minimum requirement of all audio components is that the response curve measured by the instrument is in a straight line. To enlarge the machine, magnify it with a small object to match the original image, just like a picture enlargement. If deformation, that means the expansion machine itself is distorted. In response to irregularities, the equipment itself is colored with color, which sounds like a sense of prominence or absence. The response curve of the loudspeaker system in the loudless chamber should be smoother and better. There is no curve graph, that is, how many HZ to how many HZ + - a few dB to express. The smaller the + dB number is, the more smooth it is.

The equipment has a good response, which means that it is neutral. No matter how to match the equipment, it will not change the timbre, but in fact, it is impossible to do the sound.

4 * bandwidth

The frequency range means that the device is designed to operate between a certain frequency (sound wave). Is the wider the better? Not necessarily, but there is no doubt about the progress of electronic technology. We need not be too demanding about the bandwidth characteristics of the amplifier, so long as it can faithfully amplify the signal and provide the power needed, it will be competent. But the bandwidth should not be narrower than the frequency range of the human ear. Usually 20HZ~18KHZ varies from person to person, and so does the horn system.

The number of + Db after the number of bandwidth is also important, that is, the response is smooth. For example, the frequency range of the A horn is 50 h to 20 km / H + 3 D B, -6dB35HZ35, and the B horn is marked by the range of 5, 5, 2, 2, 2, 2, 2, 2, 2, 2, 2, and 2. We know that the frequency range of the two is equal, but it is clear that the B horn is not as smooth as the A horn, because the B horn is likely to be - 6 dB at 20KHZ, and A is - 3 dB. If the frequency range of the C horn is 20 - H - 20 - K - H - H + + - 2 dB, there is no doubt that its response is more smooth and wider than that of A or B, and the bass is more extended.

5 * bass extension

The voice, the big turntable, the CD turntable, the expansion machine are all related to the bass extension, especially the horn, because it makes us hear the sound generated by electrons. The bass extension of a horn does not refer to quantity but quality. Listening to the 2 of Charles Camille Saint-Saens's organ symphony, the 30HZ organ sounds can be clearly heard, and the hair has a sense of feeling or a slight earthquake, and we can evaluate the bass of the horn to extend. Listening to drum or bass cello is heavy, thick and thick. We do not call it bass extension because the bass issued by these instruments should be above 30HZ.

There seems to be a common characteristic of the loudspeaker that extends enough bass, that is, bass sounds a bit less than that. It seems that the plump bass can not extend, and there are extended and plump people who are unable to listen at large volume (such as the transmissions) because they are limited by physical factors. Therefore, if you want to extend the bass with the aid of equalizer, do not listen to the volume at large (1812 Prelude sound gun fever + equalizer = loudspeaker reimbursement).

6 * bass rendering

Rendering is the meaning of strengthening. The music of the bass drum, the bass cello, the cello, the bass, the electronic bass drum of the pop music, and so on will be able to get its bass rendering. Some loudspeakers design their bass designs because they are used in general families. This kind of loudspeaker is below the middle volume fashion, but when it is slightly larger, it appears to be too fat and chaotic. The designer knew but ignored, because he knew that only a few people would listen at such a volume. So when reading the commentary on the horn, comments on its bass too exaggerated should be paid attention to, because it may be inappropriate for the speaker to listen to your middle bass volume. If comments say bass is not enough, maybe your listening environment is just right.

7 * * in the middle

Most of the vacuum tube machines have a high pitch personality, which is also a natural response of the treble to the extension of the crystal machine and to the hearing. Some of the horn system is also the same. Alto is the most sensitive part of human ear and the most concentrated area of all kinds of music. Therefore, for the sake of being liked, many audio products are striving for different buyers.

The prominence of the baritone undoubtedly is to please the vocal music (classical or popular), brass and piano. If you prefer music in this area, it's wrong to concentrate on selecting the equipment store that is highlighted as a pitch.

8 * * soprano

Unfortunately, there seems to be no sound equipment with high pitch and high pitch. Too much emphasis on high pitch, and the middle tone must have a thin feeling. Listen to music, piano, brass and other instruments. But high pitched delicate music is good for string music, such as violin. If you focus on chamber music, Violin and other string instruments take up most of the music, it is no harm to find high pitched or even exaggerated equipment. But be careful, fine does not mean bright, otherwise in the general apartment or cement building will feel the noise of the high tone, especially the use of CD or listen to the digital recorder.

9 * * the soprano is bright

Many musical equipment design time is divided by instruments, and the human ears need to be corrected. Correction of the human ear will be made in the appropriate audiometric room, or in the designer's home. In Europe and the United States, the building structure of Japan and other places is different from the local general residence, so it is very likely to be heard in this area. Special attention should be paid to this difference unless the environment is deliberately decorated.

High soprano is not completely inadvisable, but listening to high blood pressure for a long time above the medium volume (to be confirmed by medical personnel), but not listening to the fact. Listening to a small volume, high pitch is bright for some people. For older people, high pitched brightness may be something to pursue. But as mentioned earlier, high pitched brightness may damage three dimensional space unless the Alto is also prominent.

10 * instantaneous reaction

The instantaneous response is good, and the sense of hearing is the unison of various musical instruments. Each is clear and audible, clean and smooth. Instantaneous response is also a special term for sound electronics, which is synonymous with resolution.

Electronic subdivision is one of the ways to enhance instantaneous response. If there is no time delay, the sound will come out of a three dimensional sense of distance. The other hearing of the instantaneous response is "fast", which does not mean that the original music is 35 minutes and 28 seconds, and that the instantaneous response of the equipment is shortened to 34 minutes and 45 seconds. It is because of the quick and quick ending of musical instruments.

If we describe the instantaneous or good response of a loudspeaker, it usually means that there are some and no ones. The so-called inertness of physics does not exist - that is, after the signal is stopped, the basin of the horn will not move one or two times.

11 * diffusible

This refers to the scope of the loudspeaker's sound. The loudspeaker's voice sounded like we were blowing a balloon. The mouth is a loudspeaker, and the size of the circular balloon is the coverage of the sound. The loudspeaker's dispersal is large or good, and the sense of location of listening to musical instruments is not lost due to the movement of head or seat.

Because there is no directivity below 100HZ, when we say that this horn is good dispersal, it usually refers to the middle pitch, especially the high pitch. If the loudspeaker is to be diffused or narrow - horizontal and vertical, the central listening position is slightly left or slightly right, and the station starts to sit slowly. If the tone color of the pitch does not weaken by movement, it not only tells you the loudspeaker is good at diffusing, but the position of the horn is preliminarily qualified.

Diffusible is not as wide as possible. This can not be covered, mainly depending on the distance between the left and right speakers and the distance between seats. The two speakers must be far apart, and the seat is too large to be triangles. In principle, you need a pair of diffuse speakers. If that is the case, the seat is close and you can not put two trumpets flat on the inside. If listening to the narrow environment, the spread of the loudspeaker is bad, because the part of the sound of the two speakers is too large, and produces a bad sense of sound.

12 * * sense of sound field

This means listening to the integrity of the stage. The loudspeaker and the sound source all have three degrees of space sense, but the improper placement will produce: (1) there is a voids in the middle stage (2), the stage is small (3) the stage is shallow. How to make the best use of the loudspeaker's multiple movement and seat adjustment, and it can be said that each room is different. But it has to rely on equipment
