1. KTV sound decoration design

在KTV廳堂裝飾工程中，為了與音響系統(tǒng)配合以獲得好聽的總體聲音效果，有必要認(rèn)真進(jìn)行廳堂的聲學(xué)設(shè)計(jì)和處理。但在當(dāng)今的裝飾工程中人們存在著許多模糊認(rèn)識(shí)，以投巨資裝飾完畢的KTV音響效果卻往往難以達(dá)到預(yù)期的目的，留下很多遺憾。

In the decoration project of KTV hall, in order to cooperate with the sound system to obtain a good overall sound effect, it is necessary to carefully carry out the acoustic design and treatment of the hall. However, in today's decoration engineering, there are many vague understandings, so that the KTV sound effect decorated with a large amount of money is often difficult to achieve the expected purpose, leaving a lot of regrets.

2.聲音是怎樣來的

2. How does the sound come from

走進(jìn)KTV大廳，你會(huì)聽到美妙的聲音：直達(dá)聲與反射聲。由發(fā)聲體通過空氣中直線距離傳達(dá)到聽眾，因而音量大，到達(dá)時(shí)間早。反射聲特性：由廳堂四壁、天花、地板(簡(jiǎn)稱廳堂六面)及廳堂內(nèi)所有擺設(shè)物體多次反射的聲音組成，延續(xù)時(shí)間長(zhǎng)(因而也稱混響聲)，信息量豐富(多面反射，多次反射)，受反射面形狀與材質(zhì)的影響，因而帶上了廳堂特 有的聲音特性，所以，反射聲特性也稱“廳堂聲音特性”或“廳堂混響聲特性”。

Entering the KTV hall, you will hear wonderful sounds: direct sound and reflected sound. The voice is transmitted to the audience through a straight-line distance in the air, so the volume is large and the arrival time is early. Reflected sound characteristics: it is composed of the sound reflected by the four walls, ceiling, floor (hereinafter referred to as the six sides of the hall) and all furnishings in the hall for many times. It has a long duration (so it is also called mixed sound), rich information (multi-faceted reflection, multiple reflection), and is affected by the shape and material quality of the reflecting surface, so it brings the unique sound characteristics of the hall. Therefore, Reflected sound characteristics are also known as "hall sound characteristics" or "Hall reverberation characteristics".

3.KTV混響特性

廳堂內(nèi)的反射聲(或混響聲)組成了廳堂內(nèi)聲音的重要部份，它約占到人耳實(shí)際所聽聲音的80%的信息量，因而影響到人耳對(duì)聲音的感受好聽或不好聽，舒適或難受，呆下去或快離開。

The reflected sound (or reverberation) in the hall constitutes an important part of the sound in the hall. It accounts for about 80% of the information of the sound actually heard by the human ear, which affects the human ear's feeling of the sound, good or bad, comfortable or uncomfortable.
