| Why are things that are free cost so much? How much do we pay to have free time from work? (Think about it. How much did your last vacation cost?) Why do people still think that free acoustics costs so much? |

| 3dB is double or half of where you started from. To reduced noise 3dB you have to reduce the power of the noise by half. To reduce a reflection 3dB you have to absorb half the energy or 50% of it. |

| The most common acoustical problem a church has is excess energy between
150 to 800 hertz. Often the amount of energy needed to manage is around 20 to 25dB of reduction. To reduce the energy up to 25dB you have to reduce the power in the energy 256 times the power |
|||||||||||||||||||
| By just managing the sound between 150 to 800 hertz you can improve speech
intelligibility up to 20%. This allows you to keep a higher level of musical quality in your congregational singing and worship while improving the performance of your sound system at the same time. You can often improve the dynamic range of your sound system up to 10dB.. |

| TIPS OF THE DAY | |||||||||||||||||||
| A Church with poor acoustics is an incomplete building. A Church with good acoustics is a complete Church. Even a 450 year old church can be incomplete until it gets acoustical treatment that allows full and free flowing worship. Joseph De Buglio May 1 2012 |

| Walls are amplifiers of sound. Outdoors - when you double the energy with amplifiers or speakers the sound levels increases 3dB. Indoors - when you double the energy with amplifiers or speakers the sound level of certain frequencies can increase up to 9dB or cancel the sound 100%. April, 24, 20112 |

The ocean of air between the pulpit and the listener has many invisible perils. The biggest danger is when sound is on it's journey, destructive reflections amplified by the sound system often changes the sounds of the words. This always changes the meaning of the message. Joseph De Buglio April 16 2012 |

| First Baptist Church, Lloydminister, Sask. Canada was host to the Fredom
Singer that sold out the concert and their book. First Basptist church was featured in CBC Dragons Den Season 6 Episode 17. The acoustical treatment using the Solomon Acoustical System was shown on TV. The concert was held in November 2011. Acoustics doesn’t win people to Christ but it does prevent people from understanding the message no matter how good your sound system is. Joseph De Buglio Thursday, February 23, 2012 |

| Nothing ruins a good movie more than bad sound. Nothing ruins the worship experience more for the first time visitors than bad acoustics when the minister is preaching. Saturday, February 11, 2012 Nothing sounds better than a worship space with a flat frequency response. Wednesday, January 04, 2012 Getting speaker distortion under control. Why do older people ask you to turn down the sound system when it is not loud to younger people (PDF File) December 3, 2011 "The average church will replace and or relocate their speaker system 2 to 6 times before they will fix the acoustics." Joseph De Buglio 2011 November 12, 2011 When standing at the pulpit at your church and the sound system is off,
do you speaker louder or quieter? Church Acoustics is not optional when it comes to spreading the Gospel. October 10, 2011 All Church Acoustics begins with Solomon's Temple. October 1, 2011 September 24, 2011 "All churches are unique. Even when two churches are built alike, they will both be different and
they will sound different because no two congregations are alike and they
will always want to personalize a new building design. All churches have the same special requirements. All churches have the same basic requirements and some have advanced requirements. These requirements are not optional as they are the foundation of what
is needed to hear and participate in a large space. Management of sound in the church is to always achieve the same goals regardless
of the room shape, size and materials built from. All churches want the
same results whether the sound is amplified or not. All churches are unique.
All churches want to be unique yet they all want the same results - to
hear speech and music clearly." So you dial in a great mix when the praise team or choir rehearsed before
worship service. Everything sounds great. Everything sounds grand for the
first song. Then about half way through the 2nd or 3rd song, the music
starts to sound horrible. The balance of the vocals and instruments are
way off. It seems like the vocals and any instruments using open mics are
being turn down or the electronic instruments were turned up. Seconds later,
you hear the onset of feedback or ringing in the sound system. But how!
Everything was sounding so good just a few seconds ago. HELP!!!! Question: When is there too much bass in a church? There are two main approaches to acoustics in churches.
A room that can do all of this would be an excellent worship space that
can double as a multi-purpose worship space able to perform well for all
styles of preaching, worship and music. The big question is, which acoustical
fix will cost less? JdB Sound Acoustics uses the "EASE" acoustic modeling program for sound systems and acoustical simulations Since May 2006-2012 |

| We work on projects that have a wide range of budgets. Ready made solutions
are often high cost. If your church wants to offer some volunteer help,
the cost of fixing a worship space becomes much more affordable. Here are some examples of projects with very limited budgets. For each church the worship space was changed from a hostile non musical, low intelligibility space to a high quality space that has an almost ideal balance of musical performance with great speech intelligibility whether the sound system is on or off. |

A congregation isn't passive like the audience in a theatre or concert
hall. Worshipers play a vital, active role. Churches should be an environment
that connects the people to each other and supports their participation
in the worship and the message. |

| As you can see, it is not enough to just install and operate a great sound
system. You have to have a way to manage the air in the room. Before any
sound system can sound great, before you can move forward in improving
the worship experience, you have to manage the reflections in the room.
Manage the sequencing of sound and manage the frequency response of the
room and the results will be immediately apparent. Taking care of these
three vital issues will change the worship experience of the church members
almost instantly. When your church is ready to take the next step in it's worship experience, look for a single step solution that addresses all of these problem. These problems are often fixed for less than the cost of upgrading or replacing the speaker system of most churches in existing church and is often free when planning new churches. |
