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.
Although they did not have the advantage of modern computer modeling, historical attempts to correct the problem including adding absorbing ash to clay pots located in the walls and corners. This solution is primarily based on trial and error, with material added and subtracted until the desired clarity is achieved. Other methods included altering support pillars to redirect echo, or using specially cut stone blocks.
Today, solutions range from installing carpeting in strategic areas to using high-tech electronic reverberation systems that create a variety of listening environments. Both are effective, but neither can completely solve echo or muffling problems that are actually a product of the original building design. For many structures, a mixture of methods that also emphasizes special flat baffles creates the best results.
Rather than cutting out certain frequencies, these baffles absorb unwanted reflections, often within a particular room. They all incorporate a common design approach, using a frame that houses a filling of absorbent material, covered by a variety of decorative possibilities. The interior is most often filled with fiberglass or foam, and there are less environmentally toxic fillers also available.
Dimensions are dictated by the amount of distortion or echo. Some may be as large as an entire wall or ceiling, while others only cover a four square foot area. Regardless of size, each allows waves to pass through rather than bouncing off a hard surface, and any returning echo is re-absorbed. This method uses the same principles as music studios to reproduce vocal and instrumental tones accurately.
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.
