The same structural characteristics that produce a lovely echo when music is performed can make ordinary speech nearly unintelligible. Music is an important part of most church services, but the congregation should also be able to clearly hear and understand spoken words without straining. Acoustic sound panels for churches clarify and focus tonal vibrations, making them easier for human ears to process.
Although some European Gothic cathedrals are famous for their signature echoes, there is a distinct line separating reverberation from garbled, irritating noise. Echoes occur because individual waves repeatedly bounce back and forth between ceilings and walls. While some building plans include acoustic accuracy, many houses of worship today exist in structures originally intended for other uses.
Even without the benefit of modern computer analysis, there have been several methods historically used to correct the problem. Some included the addition of ash to clay pots located at strategic points withing a room. They were moved about, and burnt material was added or removed to dampen specific reverberations. Support pillars that dominated some buildings were specifically altered, and stone blocks specially sized to inhibit echo.
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.
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.
Rather than being an industrial-looking eyesore, these structures lend themselves to the type of decor perfect for houses of worship. They may mirror stained glass windows, or can be used to repeat various themes already existing on actual walls or ceilings. Unadorned, they may seem intrusive, but in most cases a properly installed group looks like part of the original surroundings.
It is possible to precisely arrange them in the best possible positions using digital analysis, but diffusion and absorption is often best measured by the most effective tool of all, human hearing. Once the best configuration has been discovered, units can be positioned permanently. Instead of preventing certain frequency ranges or cutting down the volume, they make both speech and music sound clean and clear.
