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 there are European cathedrals famous for their fantastic echoes, a fine dividing line separates noise from distortion. Echoes occur when the vibrations that make waves bounce repeatedly back and forth from hard, reflective surfaces. Some buildings are fortunate to include acoustic considerations in the original plans, but many churches today are housed in structures originally designed for other uses.
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.
In modern buildings, solutions vary from adding thick carpeting in specific spaces, or using software to create individual and changeable reverberation shapes based on other acoustically famous interiors. Both methods work up to a point, but cannot completely overcome structural obstacles that are part of the original building plans. Many structures benefit most from flat baffles in front of walls or on ceilings.
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.
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 place these baffles in a hall with acoustic precision using sophisticated microphones and computers, the best method of making a final determination is simply by listening critically. What seems within acceptable range to a machine may not to a human ear. When installed properly, they do not inhibit high frequencies or decrease volume, but instead increase the clarity of both speech and music.
