Ryan Skoug of ESI Engineering just returned from San Diego, California where he was an invited presenter at the 2019 Fall Conference of the Acoustical Society of America for the session on “Sound Transmission and Impact Noise in Buildings”.
ESI recently worked with a client to improve meeting room speech intelligibility for in-person, conference call, and video conference meetings. This video describes the user complaints, the existing acoustic conditions, and a methodology to improve intelligibility in these rooms.
ESI has been developing a testing and rating methodology to evaluate low-frequency, or “thudding” footfall noise through multi-family floor/ceiling assemblies that is currently ignored by today’s standardized methods.
ESI is proud to have been a team member on two of the thirteen projects recognized by the AIA Minnesota Honor Awards; the Minnesota State Capitol Restoration and the Ramsey County Library in Shoreview.
The long-awaited 2nd Edition of AISC's Design Guide 11 (DG11) was made available in 2016. This article will summarize the changes relating to Chapter 6: "Design for Sensitive Equipment and Sensitive Occupancies" and the corresponding portions of Chapter 7 relating to the same topic.
ESI finished up 2016 with a number of notable projects. One that got a lot of visibility (it was featured on the front page of the Star Tribune), was the design of the Smaaash go-kart track at the Mall of America.
ESI is pleased to welcome Arjun Shankar as an Intern in Noise Control and Acoustics this summer. Arjun will be working closely with Tony Baxter and Ryan Skoug on measurements, data analysis, calculations and reports.
