Church Sound Booth Construction

Constructing a new sound booth in an existing sanctuary is not an easy task.  My church completed construction on a new sound booth in our sanctuary a few years ago.  This article outlines our experiences and how we ended up with exactly what we needed.

Remember The Line-of-Sight

This is probably the most important piece of information you should know…sound booth operators should hear what the congregation hears.  A booth located out of direct line-of-sight of the main speakers will only receive sounds reflected off the walls and the floor.  This reflection causes sound to be perceived as softer and muddy.  This results in the sound operator increasing the volume in the main speakers so THEY can hear thereby, blasting a higher-than-necessary level of volume into the majority of the congregation.

Additionally, sound booth operators should SEE all areas of the pulpit (stage) area.  This allows operators to see when they are given cues to play a CD, turn on a microphone, or take some other measure necessary.  Given these two bits of information, only now can one look at sound booth locations.

Location, Location, Location

We found a booth can be located in one of three areas, in the wings of the sanctuary, on the second story such as a balcony, or on the ground floor.

WINGS – Our church has the main room of the sanctuary and then it has wings to the left and the right, useable as classrooms when the folding partitions are used.  A quick answer for where to add a sound booth is "place it out of the way and build it in a wing.  Great idea!  Bad idea.  Based on the design of our church and what you've just read about line-of-sight, the wing qualifies as a bad location.  
 
EYE IN THE SKY –  Depending on the setup of your sanctuary, you might have a balcony or room adjacent to the rear wall of the sanctuary.  Here's where the upper area may or may not be the best location.  A balcony that is well aligned with some main speakers and provides a line of sight to the pulpit/stage area can work.  Some churches have used the adjacent second story rooms and knocked a huge hole in the wall.  This is not an ideal location as the main speakers will never be pointed directly at the second-story section of the wall so the sound quality coming into the booth won't be the best.  Next, you need a big hole for sound to enter and to see the stage.   

GROUND FLOOR – The main floor was the ideal location for our booth. Due to the small size of the sanctuary, we placed in the back.  Depending on the size of your sanctuary, a booth can be in the back of the room or in the middle of the room.  The key here is that you hear what the majority of the congregation hears.

The booth operators should be facing the pulpit, having direct line-of-sight across the congregation to both the pulpit/stage area and the main speakers.  I recommend elevating the booth floor ~18 inches at a minimum.  An easy way to measure the correct elevation for your booth floor is the ability to see the stage if the congregation is standing and you are sitting in the booth. 

By the way, you might get the argument that wearing headphones makes any location acceptable.  That's wrong.  Headphones don't take into account general room noise (even people sitting still make noise) and sound dynamics of the room.  While you could try to compensate for this with additional microphones, it's just not a good idea.

Security – How Secure is Secure Enough?

If someone breaks into the church, they can / will break into the sound booth. Therefore, sound booth security should be based around securing the booth from "honest" people. 

Who are those "honest" people? 
1. People who use the area outside of normal service times such as home school groups or weddings.  They might assume they have free-reign if it's not secured.  Anyone using the sound booth should be properly trained.  Therefore, train one or two adults from the home-school groups or have a call list of booth operators who are willing to work outside of Sunday mornings.   

2. Youth group kids who think it would be cool to hook up their gaming console to the main screen on youth night.  Again, not that it's inherantly bad but they should have a trained individual set up their systems for such usage.  Images of a 32-ounce drink hovering over the mixer gives me nightmares.   

3. Finally, the most dangerous of the "honest" people…kids.  I know how "cool" it would be, as a kid, to sneak into the sound booth and play with the knobs and switches.

It's like this…if I get a phone call that the church was broken into, I'll expect the sound booth is now missing a lot of equipment.  Outside of that, there is no reason to see signs of an untrained person in the booth such as mixer knobs in weird settings or equipment laying all over.

Secure your sound booth with a door lock.  Then, only provide trained people with keys.  If you need to prevent hands from reaching over the booth, I suggest barbed wire…well plexiglass is good, too. ;)

Building the Booth

How big should the booth be?  – Much of this answer depends on how much space is available in your sanctuary and your needs.  In our case, we had a 13 foot run across the back of the sanctuary that was ideal for a booth.  We have operators for both the sound system and the multi-media presentations. Therefore, we liked a very long booth design with about six feet in depth.  Six feet sounds like a lot but it isn't.  You need a countertop big enough for a mixing board (around 28 inches).  Then you need room for a comfortable swivel chair.  Then you need room to move around.  Bottom line is give yourself room – tape out a section on the floor and see if that gives you enough space. 


This photo shows our booth and the space required inside.

There are now two basic types of booth to build; closed and open.  A closed booth is one in which there is a large window opening that can be opened and closed as well as a lockable door.  This is a lot of work to build and rather costly.  The pro's are a secure environment for protecting your goods.  The con's are the openings have to be high enough to permit line-of-sight to the mains.  Also, securable window closures are expensive.


The open booth design we used is pictured below.

An open booth has limited security but the trade-off is maximum visibility.  Security was a big issue that was batted back and forth between myself and my cohort.  We decided the open design was more aesthetically pleasing, significantly cheaper, and was a much better choice regarding line-of-site. 

Summary

Designing a booth for your church requires consideration of four topics; line-of-site, location, security, and size.  We found the open design sound booth with an elevated deck was ideal for our situation.  Remember a sound operator's job is providing the best sound for the congregation.  Having the right booth helps them do that job.

    My church congregation are moving shortly from a rented building to our own building very soon. I have the un-enviable task of building a sound/AV/lighting booth. The building we have purchased is very old. The acoustics are shocking. You could clap your hands, go to the loo and come back and the clap would still be reverberating around the sanctuary. What can I done to reduce the reverberation in the building? It has a very high apex roof made of timber. The walls are fairly high and painted with a fairly shiny paint. It has a timber varnished floor with timber cladding nailed up the walls to about 4 feet from the floor level. Regards the AV booth: I know roughly where to locate it. Right opposite the stage against the wall which faces the stage. The old church has 2 entances into the main sanctuary. One door is over to the left and one over on the right. My booth could be situated bang in the middle against the back wall but facing the stage. Does this sound good to you? I dont have any sizes as yet because we dont have the missives or keys to do any measuring. I’m running from memory at the moment. Love your page and website. God bless you. I’m going to keep in touch. William from Scotland.

      Hello WIlliam!

      You’ve got your work cut out for you, for sure. The sound booth location is where I would put it. I’m going to assume that you don’t have enough budget to do a full-on acoustical sound treatment in the room. I’m also going to assume you can’t do much with the floor or ceiling. So you’re left with a couple of options.

      1. Install heavyweight curtains about 8 ft. high (pipe and drape velour) in sections against the back of the stage wall and back of the sound booth. Then install them in sections against the side walls. You should only cover the entire stage wall and sound booth area. The walls can alternate open sections with the curtains. This option allows you to have moveable sound control panels and you’ve got color choices, especially if you go with Performance Fabric instead of velour. The key is to have enough curtain panels to have each section fairly convoluted with fabric.

      2. Build your own acoustic panels. I build them out of 1×4 or 1×2 and stuff an unfaced rock wool insulation into it. Then I cover it with a loose-weave cloth like burlap or acoustical fabric. Again blanket the stage and sound booth walls. The remainder can be alternated.

      3. Buy acoustic panels. This is the most expensive option.

        Thanks for your reply. The budget will be the biggest problem. Most of the funds will be directed initially at building repairs. Curtains on frames would probably be our cheapest option at the moment. I’ve found web pages with pics of sound booths in other churches so I’ve taken note and made sketches of what we will need to build to hand into the church leadership. I really appreciate your prompt response and would also welome your prayers lol. William.

    i Have planned to install sound system which is roman catholic (Kathedral). I think it is very difficult because
    of bigger crowed
