What will give you the biggest bang for the buck in upgrading the Sound of your church?

Posted by jdbsound on May 2, 2018

This 300 seat church already had a reasonable high-quality sound system.  It was properly designed for the room and professionally installed. The acoustics were not that bad.  At least it was thought that the acoustics were not such a problem.  The outstanding issues they were trying to solve or improve were:

  1. Gain before feedback,
  2. Elimination of the few deadspots that were not solved from the previous sound system when the current new JBL speakers were installed
  3. Reduce sound spill from floor monitors,
  4. Better control of the drums (when using acoustic drums) and
  5. They wanted 3dB more bass from the Sub-woofer.

These are all reasonable reasons to upgrade the sound system.

The church was considered the following upgrades.

  1. Replacing the professionally designed and installed 12-year-old JBL sound system.
  2. They considered going for IEM (in-ear monitor) system for up to 8 people. (This would have included a new digital mixer)
  3. The church considered making an air-conditioned drum booth or get an electronic drum kit.
  4. They also wanted to add a second twin 15-inch sub-woofer.
  5. Estimated total cost, almost $26,000.00 installed.

This is what the church actually did. They changed the acoustics of the room.  They installed an acoustical Tube Radiator system.

What did they gain by doing this?

  1. The sonic quality of the existing JBL speaker system was greatly improved. The improvement was noticeable better regardless of how much equalization was added or when the EQ was bypassed. (Definite proof that the acoustics of the room changed the performance of the speaker system from the day they were installed.)
  2. All of the remaining deadspots were now gone. (This was never a speaker system problem as the right speaker system design was already installed.)
  3. The performance of the speaker system was such that picking up a person’s voice went from 12 inches to 35 inches with a Shure SM58 mic before feedback would show up. (Again, acoustics limits the performance of all sound system. Sure there are some very expensive gadgets that can improve gain before feedback, but such gadget can cost more than the material cost of the acoustical fix.)
  4. The floor monitors are now well behaved. No matter how loud the floor monitors get, you definitely need to and to add the front of house to hear clear sound. As it turns out, the overall stage mix dropped around 10dB without the performers even noticing as they were now able to hear the stage mix from the monitors so well at a lower volume. You could say that the monitor spill issue is eliminated.
  5. This eliminated the need for IEM’s.
  6. Since the drummer can hear himself now, he gradually started playing quieter after a few weeks. The need for a drum cage disappeared.
  7. The Single Sub-Woofer was now able to play 9dB louder without distortion. It would have taken 3 more sub-woofers to get the same loudness without distortion. That was equal to spending around $15,000.00. (Standing waves and bass buildup in the corners added air pressure onto the surface of the cones of the subs drivers. This added air pressure creates distortion. When the subs distort, the sound quality and maximum sound levels of what the sub is supposed to be able to do, can drop up to 15dB in many rooms.)

Other improvements

Congregation Singing.

  1. The participation of people singing went up from 30% to 75%. (When people can hear themselves and the other people around them, it encourages people to sing more.)  s a resulting, the congregation is singing 8 to 15dB louder. (The more people singing, the louder they will become.)
  2. No more distortion from the speaker system with playing louder which means the perception of loudness is greatly reduced. (Standing waves and bass buildup in the corners added air pressure onto the surface of the cones of the bass driver of full range speakers. This added air pressure creates distortion. When the bass drivers distort, the sound quality and maximum sound levels of what the full range speaker is supposed to be able to do, can drop up to 15dB in many rooms.)
  3. After two years, the congregation is starting to add harmonies to their singing. (That is what happens when people can hear each other.)
  4. Now when people stand up to give testimonies or prayer requests, people can hear them whenever they forget to use hand-held wireless audience microphone.
  5. The front of house stage mix is so much better. Now you can hear all of the performers without having to blast the sound system. (A well-diffused room can make the signal to noise ratio improve from 3dB to 25dB. As the signal to noise improves, the easier it is to settle into a high quality.)
  6. The worship space is now concert quality for any high SPL event, recitals, choirs or orchestral events.

The total cost of the acoustical system including painting the whole sanctuary. $1,400.00
Since this as a DIY project, the money saved went towards a better headset mic for the pastor and the new digital mixer. Total upgrade, $5,000.00. If the church contract out the installation of the Sono Tubes, add $5,200.00. That is still 60% of the cost of upgrading a perfectly good sound system if everything is contracted out or an 83% difference.

Conclusion

One can honestly say that fixing the acoustics had a far better return on investment versus just upgrading the speaker system alone. Upgrading the speaker system can never make the room sound better, improve congregational singing and it would have not been possible to delete the deadspots without adding more speakers on delays around the room. This transformation is typical of the new worship experience when a church gets the acoustics they are supposed to have. In the battle between acoustics vs sound systems, acoustics always wins. It’s Physics. Try moving a wall with air? You can’t. Change the wall and hear what happens!

A Rant about Church Bible Studies and Mid-Week Meetings!l

Posted by jdbsound on May 14, 2015

I know I’ve had my head buried in the sand successfully getting people to come to church on Sundays.  Better acoustics and better sound does indeed equal more people coming to Sunday worship but what ever happened to the mid-week meetings where people can study the bible and have open discussions? Where do people go if they want something more than just Spiritual Milk and Pablum as what is mostly taught on Sunday mornings?  What do you do if you want to add some spiritual meat into your diet?

In recent years I have started looking at church bulletins, their web sites and have spoken to many church pastors.  Since I travel so much, it has been hard for me to get out to my own church but I do get to speak to other fellow Christians all the time.  Couldn’t help noticing that the most common thing missing from many churches is the mid-week meetings for adults.  Cell groups were popular for a while but they seem to be disappearing as well.

When the question about mid-week meeting was put to some pastors they gave some of the strangest answers ever.  In their replies they say things like, “You’re supposed to feed yourself” or “you can’t control those in the midweek meetings as it seems they all have secret agenda’s.”  or “I don’t have time to lead it.” or “people are too burned out for mid-week meeting with all of their other non-church activities” and so on.

Then I started asking ordinary church members if they would go to a mid-week bible study.  Most said yes and some liked the idea of a later evening study time between 8pm and 10pm rather than programs starting at 6:30 or 7pm.  Late enough for one of the parents to slip out after putting the kids to sleep and not so late to get up early the next morning.  Where it would be a social time as well as a study time, where a light snack and something to drink would be included.  Where it could be in a person’s home or in a room other than the worship space unless the worship space is the only room large enough to gather in.

Has social media, which I don’t use much, replace the need for human interaction?  Am I being old fashioned about how churches were growing 30, 40 years ago?  Is it just me or has the church given up on the basics in how to draw people back to church?  Do you quit bible studies just because only one or two people show up?  Are we so caught up with technology that if we don’t get rewards every 8 seconds, it’s not worth doing?  Has our attention span as Christians been reduce to something less than the attention space of a Gold Fish?

A while ago, there was a weekly bible study started by a minister’s Son.  It was for both men and women and it was not initially organized by the church.  The well planned and prepared bible studies were very successful. The church then sanctioned the study and it went on for years. Suddenly it was cancelled.  The reason wasn’t really clear but there were suggestions like, half the people were from other churches, they were growing inwards and not outwards.  A few people said that the program was self-sustaining but it was not generating any income for the operations of the church.  Seriously! The church was more concerned about profit!

After the first few years the bible study grew to a few hundred people.  Then the bible study stopped growing but it stayed strong for a number of years.  No one was certain if the growth peaked because the room they were meeting in was not large enough for more people, or because there wasn’t any more room for parking or because no one was sharing what they learned.  There was about a 15 to 25% annual turnover of people.  That makes for a very successful program considering some churches have an annual turnover of 50 to 60% for Sunday morning services which suggests there is a lot of spiritual milk being served and little to no spiritual meat being offered any other time through the week to keep people there. This bible study had both milk and meat delivered in the right order as described in the bible.

As it so often happens, this very successful program gets cancelled and another program with good intentions tries to replace it.  The new program fails and now, three years later the church is desperately trying to reboot the Bible study because since it was stopped, overall church attendance and tithing during the Sunday worship services dropped 50%.  Who knew that a bible study program not supported by the church was in fact helping the church indirectly in a huge way.  This church seats over 1000 people.  Just because you can’t see or understand how a successful mid-week bible program works or a weak midweek bible program works, doesn’t mean it won’t have an impact on Sunday worship or church growth.

There has been other events that suggests a strong desire of people interaction.  Should a Monthly men’s prayer breakfast replace weekly bible studies?  What happens to people after getting through an Alpha Meeting program?  Some churches are good at promoting 12 step programs but what is the follow-up to that?  Where do Christians go if they want something more than just milk?  Seriously!  Feed Yourself!  Nowhere does it say that in the Bible but there are many times where God says he will send a shepherd to feed his flock.  Where are the teachers to guide us through the milk to meat or even strong meat?

So if the church is not providing places for people to get something more than just milk, where do people go to seek spiritual meat?  Promise Keepers, Full Gospel Businessmen’s association, Women’s Coffee Break, Woman Alive are just a few of the many great organizations. I get the impression that the attendees are mostly people who want more than just getting milk at church on Sundays.  I think a lot of the people who go to these groups are people who are looking for some meat.  The thing is, can you receive meat in large groups?  The Bible says no.

Heb 5:11 – 14 and 1Co 3:1 -3

Meat is for those becoming mature people.  Mature people become teachers.  Teachers start teaching with milk and later teach the meat until those who grow become mature people.  Maturity is not about age, it is about knowledge, experience and being well grounded in the Word.   Jesus by example gave us the Sermon on the Mount which was mostly milk and later he preached meat to his disciples.  Preachers spread the milk and teachers give the meat.  So where does that happen?  Not by just attending Sunday services.  It is by being involved with follow-up teaching.  People are asking for more teaching but many churches have stopped.  Meanwhile I have discovered that some churches have never stopped and those are the churches that quietly move forward.

It is high time that the midweek bible study gets restored and restored soon if we want to see churches be sustained or even grow in North America.  If the church you’re attending is growing and there is no mid-week meetings, how long will that last when there is a change in leadership?  As an observer of many churches, congregations can survive with teachers and thrive without a pastor.  I’ve seen churches build a brand new facility without a pastor leading the way but a church will fall apart if there are no teachers and where there is no meat being passed on for those to become mature in Christ.
