Ryan Skoug, P.E. (Acoustics/OR) of ESI Engineering just returned from Denver, Colorado where he attended the 2019 Spring ASTM Conference for the E33 Committee on Building and Environmental Acoustics. While attending and participating in many of the collaboration areas was important, a primary goal was to participate in the working group ‘WK63897 – Determination of Low-Frequency Impact Noise Ratings’. If you have questions about low-frequency impact noise on your current or future multi-family project, ESI is ready to assist.
