Can You Hear Me Now
Kehl Brings Intelligible Speech to Central Lutheran
Stepping up to the pulpit microphone of the new sound system, the church council
president asked, “Can you hear me now?”. The congregation's affirmative reply
was mixed with joyful smiles. It was the dedication ceremony for the long awaited
sound system renovation, part of a capital project successfully aimed at improving
speech intelligibility in the sanctuary. The new sound system designed by Kehl
Associates provided greatly improved intelligibility and three-channel (Left-Center-
Right) music reinforcement for all 2,400 seats.
The system was designed based on computer models constructed by Kehl
Associates. Robert Kehl, founder, is one of the earliest adopters of computer
modeling software for loudspeaker array design. He has been using computer
simulation software in his design routine since its inception in May of 1983.
Computer modeling allows experienced sound designers to select and test the best
and most cost effective means of proving intelligible sound coverage.
The computer models were constructed based on extensive acoustical testing in the
sanctuary performed by Kehl Associates. Various loudspeaker designs were modeled
and tested for intelligibility within the model. The best solutions were selected for
implementation into the project.
The selected speech system utilizes a specially engineered central loudspeaker
cluster in conjunction with a series of custom designed under-pew loudspeakers.
The music system uses three small loudspeaker clusters and a system of compact
ceiling loudspeakers. A large sub-woofer system is located in the ancillary pipe
chambers.
Kehl Associates recommended a new sound booth be constructed in the rear
balcony. Three rows of pews were removed and a new concrete floor poured for
the new sound booth. The new control console located in the sound booth was
custom designed to match the existing mill-work.
The system includes all-digital electronic signal processing and a new Yamaha
digital mic mixer. The digital mixer allows microphone level presets for various
types of services.
