Tillamook High School
ABD Engineering & Design worked with ZCS Engineering & Architecture on their seismic upgrade and renovation of the Tillamook High School Auditorium. The articulated ceiling needed to be removed and replaced while maintaining the existing room acoustics in the space for plays, music performances, lectures, and assemblies.
The Tillamook High School renovation was focused on seismic upgrades. Due to the upgrades needed, the ceiling of the Auditorium House had to be removed. The existing ceiling was intentionally shaped to support the acoustics of the space. So, removing it would change the character of the space.
ABD’s acoustical consultants performed reverberation time measurements in the auditorium prior to ceiling demolition. Data collected on site was used with architectural drawings to create a computer model of the space with the existing articulated ceiling. The modeling gave us the information needed to provide recommendations for the acoustical treatment materials, square footage, and locations to maintain or improve the acoustical performance in the space while meeting the tight project budget.
The challenge was to find products to replace the existing ceiling that were economical, easy to implement, and didn’t interfere with the existing theatrical lighting that could not be moved. ABD recommended acoustic reflectors that were an “off the shelf” product. So, the cost and installation were less expensive.
The new acoustical ceiling features curved reflectors designed to evenly distribute sound throughout the seating area.
