Abstract
A car wash is installed in one corner of a large industrial building with the exit feeding into the building interior. The building interior is largely open space with a high roof. This houses multiple activities going on at any given time including part fabrication and vehicle retrofitting. The space available for the car wash necessitates the exit door to open during the drying cycle. The blower noise during the drying cycle with the exit door open is not loud enough to require hearing protection in the facility. The functions held within the space eventually expanded to include meetings requiring speech communication. The noise during the drying cycle was loud enough to disrupt audibility. An ad hoc team worked to reduce noise levels sufficiently to allow all other activities to continue without noise disruption during car wash operation. This paper addresses the diagnostic work and countermeasures put in place to achieve this goal.
