Acoustical Design and Sound Insulation
Lennox School District
2013 - 2016
As part of the settlement agreement between Los Angeles International Airport (LAX) and Lennox School District, LAX is providing funding to sound mitigate one pre-school, five elementary schools, one middle school, and three high schools impacted by aircraft noise. CSDA was contracted to provide design solutions for one middle school and two elementary schools.
CSDA provided the acoustical testing, architectural design and construction administration services to acoustically treat Lennox Middle School, Jefferson Elementary School and Buford Elementary School to reduce interior noise levels to meet the 45dB standard. The Lennox Middle School project encompasses seven buildings including 45 classrooms (43,237sf) and a gymnasium (9,011sf). The Jefferson Elementary School project includes three buildings, including 25 classrooms (15,028sf). The Buford Elementary School includes 30 classrooms, two staff prep rooms, two offices, and one library (31,100sf).
Acoustical remedies are being made to the exterior and interior of the buildings. Exterior remedies include treating the exterior walls with sound insulation and installing sound abatement devices on rooftop HVAC units. Interior modifications to classrooms include the installation of sound proof windows and doors. Interior modifications to classrooms include the installation of new sound absorbent ceiling tiles and panels. Since construction is occurring while the school is in session, six temporary classrooms have been set up to allow phased construction of six classrooms simultaneously.
