Dear Sir/Madam,
On Thursday March 9, 2023 in response to a complaint from a resident, the Salem
Board of Health conducted sound meter readings at Prestige Car Wash located at 51
Canal Street in Salem, MA. The complainant's residence, which is also the closest
residence to the car wash, is 15 Ropes Street in Salem, MA.
Sound meter readings were taken in the morning and in the evening. The sound source
under investigation was the blowers at the end of the automated car wash. These
blowers are used to dry cars as they exited the automated car wash. The car wash
blowers turned on and off intermittently as cars went through the car wash, so sound
level readings for when the sound source is on also rose and fell intermittently. The
following are information and data pertaining to the readings:

paused. The reading was resumed when the carwash blowers turned off.
