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.
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 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.
Their size depends the extent of the echo and distortion. Some are as small as four square feet, while others may be nearly wall-sized, and most solutions require combinations. No matter their dimensions, they allow vibrations to pass through the exterior material rather than bouncing off, and any waves that return are re-absorbed. This principle is the same one used by music studios to emphasize accuracy, and can be easily adapted to churches.
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.
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.
