- Services: Acoustical Consulting
Description
When Los Angeles’s strict noise regulations for schoolrooms mandated full acoustical testing of all HVAC units, DHDI was chosen to perform extensive tests and measurement. The end result being the protection of students’ hearing, improved intelligibility, increased attention span, and higher learning retention in LAUSD schoolrooms.
DHDI utilizes the Bruel & Kjaer 2250 acoustical testing system.
