Acoustics: Analytical Thinking by Apocalypse



Acoustics...How Important?

A church’s physical size and structure, as well as sound requirements for the service, cover a broad and varied range.
The majority of churches require some acoustical treatment. 
And it is best to hire a trusted outside firm to handle the job (visit other churches where that firm has cured acoustical ills).
That said, before hiring an independent professional to do a thorough acoustical analysis of your church, it is a good idea to get a ballpark estimate of what it will take to fix the problems.
By the way, dispel yourself of the myth that acoustical challenges — especially severe ones — can be cured by console equalization, or even “room EQ.”  Here’s the information you need to provide an off-site analysis of your space/room acoustics: 

Room Dimensions
 This information allows the calculation of total room cubic volume, which is necessary to determine the existing sound absorption and derive the change needed to reach a desired acoustical result. Include length, width, height plus sides and ceiling peak.

 Surfaces
 What is the existing composition of the floor, walls and ceiling? Marble, carpet, wood, drywall, masonry, acoustical tile, drywall and plaster will all contribute their unique sound properties to the acoustical environment. The addition of acoustical material does not produce a change in total sound absorption by its full rating unless the surface being covered is extremely reflective. If the existing wall has some absorptive value, a new layer of acoustical material may provide only a marginal difference in absorption. 

 Seating
 Is seating hard or soft? Padded pews will prevent a big difference in sound when attendance may be down — during summer vacation, for example. If all surfaces are hard (marble floors, wood ceilings, plaster walls and wooden pews) acoustics will vary more with attendance and season. Heavy winter coats will reduce echo whereas summer attire and fewer folks will provide less absorption, allowing more reverberation.

 Capacity
 As implied above, there may be a need to compromise acoustics between perfect attendance and vacation time. How many people (maximum, minimum, typical) attend and how often? Do you want it to sound good most of the time? 

And Many other things Like Photos, Types of Service, Reverberation Time will give good information for independently asses and analyze a solution for the space/room.
