Welcome to JdB Sound Acoustic Services
If your looking to design a church, you have come to the right place.
Church Architect Design Work
Project in Progress for Acoustical and Sound System repairs.
The Pictures and details below are
incomplete.
Please come back often as this page
will
be updated bi-monthly or as time permits.
If you need details about any of these
photo's
or projects, please call or email me.
First Baptist Church, Norman Oklahoma
This project may look picture perfect, but
it is not. Not because it was a bad
installation,
but because the church changed the
rules
after the system was installed. Here
is an
example of a well installed sound system
that the church out grew and to top
things
off, the church added 20 feet to the
stage.
Seating 1000 plus choir and musicians
In changing the stage, the church now
had
to face a number of issues.
- The cluster is now behind the pulpit by 10
feet.
- Most of the musicians are performing between
large parallel walls
- The church used to have acoustical tile on
the ceiling and changed it to drywall.
- Because of the high absorption rate, wider
dispersion speaker were used. This contribute
to major feedback problems when the room
changed but the system was not altered or
reinstalled.
Front View of the church
After checking out the whole sound
system,
I was very impressed by the original
company
that installed the sound system back
in 1979.
Intelligibility was very good when
the air
conditioner was turned off.
Grace Church, Roseville, MN
Seating 750 people
It's hard to believe that two churches
700
miles apart having the exact same problem.
The original system was well installed
with
the known knowledge of the day. Like
the
church in Oklahoma, they too added
20 feet
to their stage.
Bible College Sound System
St. Martin Church, Williamsburg VA.
A new church parish hall that has omitted
many of the design details I was asked
to
supply. I had supplied many no cost
details
and other details the church was more
than
willing to pay for as extra's, but
were ignored
by the Architect in charge.
Results are as follows of the items
I address
in reports before the construction
of the
building started:
NC50
Over 3100 square feet of the interior
walls
are not insulated.
The stage acts like a drum
The RT60 was over 3 seconds. The diffusers
brought it down to 2.4
There are 4 air systems instead of
1 - at
least they could have put them on a
single
control
The air supply is greater than the
return
air speed - there is supposed to be
20% more
return air flow than the supply air
speed.
These are just some of the design details
that were ignored
Seating 350
Community Church, Oshawa, Ontario. Canada
A new church
Seating 2600
More Projects on the books
This church is brand new and it need open
heart surgery for their acoustics and once
that is fixed,
then the sound system needs to be re-installed.
