DIY DJ Setup SPL Measurements

We provided sound for a private back-yard party on 6/6. This event required the ability to comply with Poway municipal code for noise abatement. Limit of 50dB SPL at the adjacent property required. The SPL meter was set to the 60dB setting (which is the lowest range on the meter), with A-weighting, and slow response. The meter was held on the inside of the property close to the adjacent lot. Average SPL of 56dB registered on the meter with a reasonably loud sound level at the party area. The test was concluded at this point since the adjacent property is another 30 feet away from the meter location, and a row of Eucalyptus trees and other brush between serves to attenuate the sound more than the required 6dB as measured.
