– Acoustical treatment
– Sound system renovation
- Cardinal Acoustics
St. John Vianney Catholic Church located in Bettendorf, Iowa was experiencing poor sound quality and significant echo throughout their sanctuary. This stunningly beautiful sanctuary is perfect for near 360 degree seating with ample space. However, it is constructed of hard, non-absorptive surfaces, which results in significant reverb times (echo) due to the collection of sound wave reflections coming from so many different angles and surfaces. This reverb creates an acoustical challenge, causing reflections to reach the parishioners at different times, making it difficult to understand the orator’s spoken word through the sound system.
A two tiered approach would be required:
- Solve the challenge of the sanctuary with an acoustical treatment design that could reduce the reverb time from 3 seconds to 1.5 seconds.
- Design the appropriate distributed sound system to maximize coverage with an even sound pressure level resulting in less than 1.5 decibel variance from seat to seat.
Space mapping and 3D modeling were used to determine the best areas to undergo acoustical treatment. Aesthetically pleasing sound absorptive panels along with a new, well-balanced, sound system allowed us to achieve better than expected results.
