KSG Renovation Brings Applause from St. James Parish - Duluth
Acoustical Treatment And Sound System Upgrades at St. James Parish
Sermons at St. James Catholic Church in Duluth were difficult to hear and understand.
Although local parishioners could partially understand the words being spoken, visitors
routinely reported having trouble hearing the spoken word. The previously purchased sound
system, an expensive state-of-the-art line-array system, was simply not providing the needed
speech intelligibility.
KSG Sound & Video was called in to assess the situation. They conducted on-site acoustical
testing, which confirmed the cause of the problem. The critical acoustical engineering
necessary to match the sound system to the acoustics of the Nave was not performed by the
installer of the previous sound system. This, coupled with the poor physical acoustics of the
Nave, resulted in inadequate speech intelligibility.
Years before, alterations to the ceiling structure of the Nave had changed the acoustics of the
space. The alterations caused the acoustics to become off- balance, with excessive mid-tone
reverberation. This lowered speech intelligibility in the Nave.
KSG offered a low-cost solution that included a series of low-visibility acoustical treatments
intended to re-balance the Nave acoustics, with little or no change to the appearance of the
space. The acoustical treatments were matched to the faces of the arched supports and
custom cut to fit. The acoustical treatments for this project were accomplished in three
phases, with testing and adjustments performed between each phase. The treatments
provided improved acoustical control and gave the finished room a better balance of
reverberation, improved tonal response, and improved speech intelligibility.
KSG also provided a new low-cost engineered sound system,
designed to further enhance speech intelligibility in the Nave.
The loudspeakers of the new sound system were
mathematically engineered, positioned, and aimed, to match
the room geometry and acoustics. The sound system was
professionally equalized and tuned for the Nave, A digital
feedback suppressor eliminates feedback from microphones
while push-button presets allow for intuitive, user-friendly
operation.
Father Richard Kunst worked closely with KSG during the fine-
tuning stage of the project. He said, “What you did in this last phase made all the difference
in the world.” KSG’s success was “literally applauded by the congregation!” according to
Father Kunst. “I’m very happy with what KSG was able to do with the sound in our church, a
night and day difference.”
