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. SOUND REINFORCEMENT SYSTEM DESIGN is one of the specialty design services offered by Kehl Associates.  We provide sound system design services for all types of facilities.
