Dear Sir/Madam,
On Thursday October 12, 2023 as a follow-up to a April 13, 2023 sound meter reading,
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. 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:
