Unless otherwise indicated, any decibel (dB) measurement made pursuant to the provisions of this article shall be based on the reference sound pressure and measured with an approved sound-level meter. Reference sound pressure will be measured as LAeq for A-Weighted and LCeq for C-Weighted.
(A) Except as provided in division (C) below, Residential, Commercial, Downtown Arts and Entertainment Focus Area, and Industrial/Manufacturing properties are to be measured from inside the Structure located on the receptor premises. Any indoor noise measurements for compliance purposes should be taken in a location which could be reasonably assumed to affect one or more persons. For residential receptor premises, inside noise level measurements are performed in sleeping or living areas with windows opened to approximately 25% of their maximum in residences without mechanical ventilation and with windows closed for residences with mechanical ventilation.
(B) Public premises are to be measured at a reasonable distance from walls or similar large reflecting surfaces and with the approved sound-level meter protected from the effects of wind and other extraneous sounds by the use of screens when appropriate.
