我们在工作室中使用哪种类型的墙壁泡沫?我们为什么要完全使用泡沫?泡沫应该有多厚?我们将泡沫放在哪里?有些墙比其他墙更需要泡沫吗?让我们退后一步,看看关于工作室中墙壁泡沫的决定所涉及的所有问题。我们房间内的音能分为两种主要类型。我们的波能低于100 Hz。我们的中间和高频能量均超过100 Hz。两种能量类型都需要截然不同的技术来治疗。 Lower frequency energy treatment types are heavy and take up from 12 – 16″ of space to treat. Middle and high frequency issues can be treated with absorption or diffusion. Most middle and high frequency treatment technologies range from 2″ – 6″ deep depending on the frequency and amplitude of the energy they are working to absorb. Most people confuse these two types of energy forms and the associated treatment types. Let’s examine both forms and the treatment types and options that are available for both forms of energy within our rooms. At the end of this discussion you will know what foam for walls in studio to use.

低频能量低于100 Hz。需要采取完全不同形式的中间和高频能量的治疗。低频能量是波能。想想海浪。这将使您了解低频外观和行为的样子。海浪能量像海浪一样在我们的房间中振荡。低频波能量长而强大。低频能量可以长20-30',高15-20'。它充满了我们的房间,可以产生房间模式。房间模式是我们墙壁表面积之间的过量能量。 We have axial modes which are between two parallel wall surfaces. We have tangential modes which are between four parallel surfaces and then we have oblique modes which are between six surface areas. To soak up the excess energy created by these low-frequency issues, we need technologies that have a pressure base to them. They must be able to deal with pressure from low-frequency wave energy. There are three types of low- frequency management available under our current laws of physics.https://www.acoustidefields.com/product/acda-10-studio/

低频吸收技术有三种类型。我们有Helmholtz,diaphragmatic和膜。这三种技术类型均涉及低频能量压力。中间和高频吸收可在气流穿过声音吸收材料类型的表面上起作用。较低的频率技术对较低频率能波产生的压力波反应。Helmholtz谐振器通常是一个管,顶部的插槽。管的长度确定吸收器的工作原理。Helmholtz谐振器在狭窄的频率范围内工作,您需要在房间周围放置多个单元。https://en.wikipedia.org/wiki/hermann_von_helmholtz隔膜吸收是三种类型中最强大的。它比Helmholtz或膜吸收器吸收每平方英尺的能量更多。膜吸收器是表弟,吸收膜吸收器。https://asa.scitation.org/doi/pdf/10.1121/2.0000816它以与隔膜吸收器相同的原理运行,但使用材料类型较少。由于这是一种低频吸收技术,涉及压力波,因此材料类型的越轻,人的性能就越少。//www.j-thinker.com/product/carbon-panel/

可以使用开放的电池声泡沫来实现中和高频吸收。泡沫技术有两种类型。我们有闭孔泡沫,这是您的沙发和座垫中使用的泡沫类型。闭路结构旨在支撑重量。泡沫公司用于运输产品通常是闭孔泡沫类型。开放的细胞泡沫是用于吸收声音的类型。从定义上讲,它具有开放的单元,可以使声能进入泡沫并产生摩擦。摩擦会产生热量,然后产生能量转化。然后,这种能量变化会产生吸收。并非所有开放的单元格泡沫都相等。 There are foams that are designed to absorb as much energy as possible and there are foams that are designed for music and voice. When searching for answers on what foam for walls in studio, you must use an open celled foam that is specifically designed for music and voice. At Acoustic Fields, www,acousticfields.com we have spent 8 years and over 2 M creating an open celled foam technology specifically for music and voice.//www.j-thinker.com/product/acoustict-foam/

我们的Studio Pro Foam专为音乐和声音而设计。它具有适当的音乐和声音吸收速度和水平。音乐和声音与噪音不同。为了实现两个主要目标,您必须使用特定的速率和吸收水平来进行音乐和语音。首先,您必须通过频率范围吸收每个八度频段的足够能量,以对房间内的语音和音乐的表现值产生可听见的影响。其次,您必须以音乐和声音所需的适当速度和吸收水平吸收。频率范围从125 Hz。- 500 Hz。是一个关键的频率范围,必须在任何用于处理音乐和声音的开放式电池泡沫中考虑。查看上面的图表,显示了我们的Studio Pro泡沫技术的性能。 Notice the smooth rates and levels of absorption that occur between 125 hz. and 500 hz. This is the critical frequency range that must be dealt with in this same manner when considering any foam for walls in studio.
