Home theater audio refers to the audio specially configured for movie playing. As the name suggests, its sound effect should be similar to that of cinema, so the low configuration should be 5.1, decoding Dolby, and DTS to realize surround sound. Different from the home karaoke system and CD music system, the home theater audio configuration has a high starting point. The home karaoke system and CD music system can be realized with 2.0. There are many aspects involved in home theater audio, such as the layout of power amplifier, loudspeaker, speaker, and the treatment of sound field environment, which will affect the sound quality.

喇叭擺放的位置

Position of loudspeaker

喇叭的擺放是音響使用中重要的一環(huán)，擺得不好難免令回放效果大打折扣。如何在房間中找到好的擺放位置頗考人功夫，除了不斷細(xì)心聆聽(tīng)不同擺放位置的效果外，還可以請(qǐng)相關(guān)的來(lái)進(jìn)行指導(dǎo)。

The placement of speakers is an important part of the use of sound, so it is inevitable that the playback effect will be greatly reduced if the speakers are not placed well. How to find a good place in the room is quite a test of people's Kung Fu. In addition to listening carefully to the effect of different places, you can also ask relevant experts for guidance.

盡量避免機(jī)疊機(jī)

Try to avoid machine stacking

應(yīng)盡量將主要的CD訊源及擴(kuò)音部分獨(dú)立來(lái)擺放，因?yàn)橹丿B擺放會(huì)導(dǎo)致諧震而影響機(jī)器。當(dāng)喇叭播放音樂(lè)時(shí)，空氣的震動(dòng)令器材跟隨震動(dòng)，兩部機(jī)相疊便會(huì)互相傳道諧震，令到音樂(lè)中的細(xì)微訊息模糊不清，并且干擾各頻段的傳送，造成一種聲音的污染，又如其中一部是CD機(jī)，自身播放碟時(shí)馬達(dá)連轉(zhuǎn)又加劇了諧震幅度，影響就更大。所以要把器材獨(dú)立置放在穩(wěn)固機(jī)架之上。

The main CD source and amplifying part should be placed independently as far as possible, because overlapping will cause harmonic vibration and affect the machine. When the loudspeaker plays music, the vibration of the air makes the equipment vibrate. When the two machines overlap, they will transmit harmonic vibration to each other, making the subtle information in the music blurred, and interfering with the transmission of each frequency band, causing a kind of sound pollution. Another example is that one of them is a CD player. When it plays the disc itself, the continuous rotation of the motor aggravates the harmonic vibration amplitude, and the impact is even greater. Therefore, the equipment should be placed on the stable rack independently.

干擾越少聲音越靚

The less interference, the better sound

室內(nèi)的家用電器及計(jì)算機(jī)應(yīng)避免與音響共享一組電源，即使要放在一起也應(yīng)從別處獲取電源。其次讓接線糾纏在一起也會(huì)令線與線之間互相吸收噪聲破壞音質(zhì)。無(wú)論是器材還是連接線，都應(yīng)該保持不受其他電器或者電源線的干擾。

Indoor household appliances and computers should avoid sharing a set of power supply with the audio, even if they should be put together, they should also get power from other places. Secondly, entanglement of the wiring will also make the lines absorb noise and destroy the sound quality. No matter the equipment or the connecting line, it should be kept free from the interference of other electrical appliances or power lines.

昏暗環(huán)境有助聆聽(tīng)效果

Dark environment helps to listen

關(guān)了燈聽(tīng)音樂(lè)是一個(gè)習(xí)慣上的問(wèn)題，可說(shuō)與回放扯不上關(guān)系，只是在漆黑的環(huán)境中，耳朵會(huì)特別靈敏，而且減低了視覺(jué)上的障礙，對(duì)音響畫面重組以及樂(lè)器的位置感便會(huì)格外感覺(jué)清楚明確，氣氛之佳與開(kāi)亮燈時(shí)更相去頗遠(yuǎn)，還可以用其他一些比較幽暗的燈光來(lái)營(yíng)造聽(tīng)音氛圍。

It's a habit to listen to music when the lights are turned off. It has nothing to do with playback. It's just that in a dark environment, the ears are particularly sensitive, and the visual barriers are reduced. The sense of reorganization of the sound screen and the position of the musical instruments are particularly clear. The atmosphere is far better than when the lights are turned on, You can also use some other dim lights to create a listening atmosphere.

吸音要適當(dāng)

Sound absorption should be appropriate

在一般的家庭環(huán)境中，家私雜物已經(jīng)是上好的吸音材料，大可不必把吸音搞得太繁復(fù)，鋪一張地毯就已有基本的加強(qiáng)吸音效果。加上地毯的好處是可減少地板的反射聲，避免混和正面?zhèn)鱽?lái)的聲音造成混濁。喇叭距離后墻太近時(shí)，也可以考慮加一幅掛毯以增加吸音效果，但要注意不可用太大塊，否則可能連超高頻也吸掉。

In the general family environment, furniture and sundries are already excellent sound-absorbing materials. There is no need to make the sound-absorbing too complicated. A carpet can basically enhance the sound-absorbing effect. Plus the advantage of carpet is that it can reduce the reflected sound of the floor and avoid the turbidity caused by the sound from the front. When the loudspeaker is too close to the back wall, you can also consider adding a tapestry to increase the sound absorption effect, but you should pay attention not to use too large pieces, otherwise you may even absorb the UHF.

另外，房間的玻璃及鏡都會(huì)有較強(qiáng)的反射聲音作用，需要用窗簾來(lái)遮擋以解決問(wèn)題。要求高的朋友更不妨在墻角位置及室內(nèi)的聲音反射點(diǎn)上多做些吸音功夫，但要注意吸音不可過(guò)分，適量的反射聲是有助于聲音生猛活潑的。

In addition, the room's glass and mirror will have a strong role in reflecting sound, need to use curtains to cover to solve the problem. More demanding friends might as well do more sound absorption in the corner and indoor sound reflection points, but pay attention to the sound absorption can not be too much, the right amount of reflected sound is conducive to lively sound.
