Music and speech are both improved by a small amount of reverberation, but at higher levels it can make both seem annoying and garbled. The choir and sermon are an integral part of many services, but become meaningless when the congregation is unable to hear singing or distinguish words normally. Acoustic sound panels for churches focus amplified waves and natural vibrations, making them more meaningful and pleasant to listeners.
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.
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.
Far from appearing to be an industrial or high-tech intrusion, these structures easily blend with most modern church decors. They can mirror the patterns and colors of existing stained glass, or can tie a room together by adopting patterns or colors on existing walls and ceilings. While a plain baffle is not particularly attractive, in many cases they end up looking like a part of the intended interior design.
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.
