In some large buildings musical tones fade away in a pleasant echo, while speech is nearly impossible to understand. Even though religious music plays an important role during services, a congregation must also hear the spoken message without having to unnaturally strain. Acoustic sound panels for churches solve this problem by focusing the individual vibrations, making them easier for people to hear and understand.
Some European cathedrals are noted for their lush reverberation, but a very fine line separates a pleasant echo from a noisy, irritating mix of garbled words. Most reverberation is caused by noise bouncing off of hard surfaces such as walls and ceilings. Although there are some buildings that take acoustics into account in their original design, many churches are located in structures that have been re-purposed.
Even without the advantages of computerized modeling, there have been many past attempts to correct this issue. In some churches, absorbent ash was added to pots made of clay, which were then placed near walls and in corners. This trial-and-error method took time, and ash was added or removed as needed. Other ideas included redirecting echoes by altering the interior pillars, or by incorporating grooved stone blocks.
Current solutions range from high-tech reverberation systems that are able to create interchangeable custom acoustic environments, to simply installing thick carpeting in specific areas. These are not ineffective, but neither solves problems of muffling or echo that are a result of the original and unalterable interior building design. For many rooms, the best solution incorporates flat, standing or attached wall panels that inhibit waves.
These structures are not used to block or eliminate words or music, but rather to absorb unwanted excess, usually within a single room. Most incorporate the same basic design method, featuring an inner filling made of absorbent material, a frame, and a covering. The filling may consist of various synthetic foams or fiberglass, or may utilize newer, more environmentally friendly substances.
Size depends on the amount of correction necessary. Some are relatively small, less than four feet square, while others cover most of a wall space. Regardless of actual dimensions, each allows individual waves to pass through rather than bouncing back, and any recurring waves are simply absorbed. A similar method is used by recording studios.
Instead of seeming like an ugly industrial installation, these baffles easily adapt to the desired interior look of a church. Some re-create the existing patterns of stained glass in the windows, or can mimic or repeat patterns or colors in ceilings and walls. While they are visually uninteresting without decoration, a professionally designed grouping normally fits in well, and can even feel like part of the original decor.
While it is possible to precisely position or arrange them for the best absorption and diffusive characteristics using computer analysis, most are placed using the expert imaging made possible by the human ear. Once that sweet spot has been found, they are permanently attached. Rather than deadening volume or preventing certain frequencies from being heard, these structures clarify music and speech.
