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.
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.
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.
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 actually eliminating or blocking certain frequencies, they absorb the excess that confuses the ear. Most construction is fairly simple. There is an inner layer of dampening material surrounded by a rigid frame, and the exterior is covered with a variety of decorative materials. Fillings are commonly made of fiberglass, insulating foam, or newer, less environmentally hazardous materials.
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.
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 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.
