5 1 sound system. 5 0 standard of good sound quality

Summary. 2 Roundness and roundness refer to distortions, especially sounds with minimal distortion in the midrange and high frequencies, which feel pleasant and pleasant. The bass is not muddy, the midrange is not stiff, and the treble is not deafening.

The hairs are the opposite of roundness, and the main sensation is that the voice is rough and audible distortion. If there is 5% distortion in the sound, the average person will have the feeling of hairiness, and professionals can hear it up to 3%.

The standard of good sound quality of the audio.

Dear, hello Ya, Happy New Year, Happy New Year, Happy Year of the Tiger, oh [Cerebellar Axe] [Cerebellar Axe] [Cerebellar Axe] <>

<> standard of good sound quality can be judged according to the following methods.

1. The sound produced by the clear and voiced sound system should be clear, the frequency response should be wide and uniform, especially the density of the middle and high frequencies, and the reverberation should be appropriate, so that the timbre and position of the instrument can be better distinguished, otherwise it is called voiced.

2 Roundness and roundness refer to distortions, especially sounds with minimal distortion in the midrange and high frequencies, which feel pleasant and pleasant. The bass is not muddy, the midrange is not stiff, and the treble is not deafening. The hairs are the opposite of roundness, and the main sensation is that the voice is rough and audible distortion.

If there is 5% distortion in the sound, the average person will have the feeling of hairiness, and professionals can hear it up to 3%.

3 Plump and shriveled sound is thick and loud, with good sense of medium and high frequency, sufficient reverberation, and good transient response is called fullness, otherwise it is shriveled.

4 Bright and gray and dark refers to the balance of high, middle and low tones in the whole vocal range, the mid and high tones are slightly prominent, and there are rich harmonics, moderate reverberation, and small distortion. Gray refers to a severe lack of high-mids, loose bass, and poor resolution.

5 Wide vs. thin and wide sound has a good frequency response, with bright treble and ample bass, and thin sounds often lack bass or treble.

6 Dry and wet mainly refer to the reverberation effect. The reverberation time is short and the depth is insufficient. The reverberation is excessive, and it appears to be wet. The wetness of the sound is sometimes determined by the software, but it can also be caused by the listening environment.

First of all, the choice of audio should be based on sound quality, whether the product has excellent timbre, beyond the imagination of the degree of restoration, excellent pitch effect, is the best choice for audio. In addition to sound quality and timbre, there is also balance, density, speed, analysis, and so on.

The choice of audio should also be based on the size of the listening room area, do not choose too large speakers for small spaces, and do not choose smaller speakers for large spaces, so as to avoid economic waste and lack of performance.

The first thing to consider with audio equipment is the speaker, mainly the orientation of timbre. The speaker is the terminal of the audio equipment, just like the voice of the person who sings, no matter how beautiful the face is, how good the figure, the voice will be bad for a thousand miles.

And it is the weakest link in the entire audio system, because it is in the process of converting electrical energy into sound energy, it will inevitably produce some distortion, and the distortion of other equipment is a few ten-thousandths to hundreds of thousandths, but its distortion is in a few percent, and products less than one percent are almost rare. It is deceptively simple, yet it is the most complex.

I recommend you to use the American BSOE speakers. Good sound quality.

Sound processing is currently the perfect sound solution, which can meet the super requirements of computer games and home audio, and the traditional two-channel sound has also withdrawn from the stage of advanced audio.

In order to get the most out of multichannel, it is essential to have a clear understanding of how to configure and use the entire system.

Channel sound equipment should include: 2 front speakers, 2 rear speakers, 1 center surround, 1 subwoofer, these five channels are independent of each other, where "The 1" channel is a specially designed subwoofer channel that produces subwoofers in the frequency response range of 20 120Hz.

It is still very easy to choose the audio, I can help you choose together, give you some good suggestions, for your reference, first of all, Dynaudio and Edifier are still good, Dynaudio audio fakes are more, you must pay attention to distinguish; The current level of cabinet craftsmanship of the edifier is OK, but the quality of the speaker, objectively speaking, in the same price of products, in these high-end producers should be counted backwards, simply say BT-audio AB HIFI set, AB bookshelf box is a HIFI box with excellent comprehensive performance, reproducing the classic pure British sound. Using super instantaneous reaction unit, the treble is not scattered, the bass is not sticky, the strong sound is not dry, the weak sound is not false, the warm and mellow sound shows the infinite charm of the **, you can feel the legendary and charming melody of the British sound, and enjoy the bloodline, sound quality, and workmanship are all excellent HIFI speakers.

The style contained in the AB bookshelf box comes from the unique design of BT-Audio's sound engineers, with a refined and elegant appearance, to create a bedroom and study desktop HIFI speaker. The first-class workmanship and sound quality have created the myth of high-end and low-price in the audio industry, and completely brought the concept of parity to the extreme!

It can be understood this way.

There are a total of six channels: ** channel, left channel, right channel, left surround, right surround, and subwoofer channel.

The purpose is to restore the recorded scene and increase the presence effect.

Channel output refers to whether the DVD player can output audio in channel mode. Among the various sound field decoding and sound field technologies, the most common, or the most standard, is the channel output, such as Dolby, etc., and other standard decoding methods can also be well output through the channel channel. The channel output includes ** channel, front main left and right channels, rear left and right surround channels, and the so-called "subwoofer channel", which can be connected to at least 6 speakers in total.

**The vocal voice is responsible for replaying the dialogue of the characters most of the time; The front main left and right channels are used to compensate for actions and other sounds that are outside the screen** or cannot be seen from the screen; The rear surround sound effect is responsible for the periphery and the entire background**, making people feel like they are in the whole scene**, the shock of thousands of galloping horses, and the effect of jets whistling overhead, is due to it; The sound of a motor, the sound of a bomber, or a drum is the most powerful bass, and the subwoofer is the only one.
