RSG Principal to lead revisions to international acoustics standard

Ken Kaliski, Principal at RSG, was appointed as Project Leader for the revision of ISO 1996-1 during the International Organization for Standardization (ISO) ISO/TC 43 “Acoustics” Plenary Meeting in Montreal, Canada, held from May 2 to May 6, 2023. The ISO 1996-1 is an international standard on acoustics, focusing on the description, measurement, and assessment of environmental noise.

In his new role, Ken's duties will include managing the ISO standard's content to create an updated international standard. This task will require collecting the most recent research for drafting the standard, fostering agreement among the global community, and facilitating several comment and response rounds. ISO delegates will then vote on the updated standard. Ken will supervise the process as Project Leader.

“I'm thrilled to take on the Project Leader role for the revision of ISO 1996-1, Acoustics — Description, measurement and assessment of environmental noise — Part 1: Basic quantities and assessment procedures,” Ken said. “I eagerly anticipate contributing to a global agreement to enhance the procedures that practitioners rely on. I'd like to extend my gratitude to the previous Project Leader, Stephen Keith, the US delegation for their nomination, and Douglas Manville, the Convenor of Working Group 45.”

RSG's noise control engineering service depends on national and international standards like ISO 1996-1. Ken's role as Project Leader will ensure these standards remain current and relevant. The final revised standard will contribute to enhancing our service quality and helping our projects earn acceptance from clients and regulators.

184th Meeting of the Acoustical Society of America

RSG Principal Ken Kaliski, PE, QEP, INCE Bd. Cert. will present during the 184th Meeting of the Acoustical Society of America on Tuesday, May 9, 2023.

Ken's presentation, titled “Challenges in Post-Construction Sound Monitoring for Rural Wind Projects,” will discuss the unique challenges faced during post-construction sound monitoring for rural wind projects. The presentation will cover various issues such as safety, wildlife, harsh weather conditions, access to remote sites, difficult protocols, and noise contamination, and how these issues arise in the context of several recent post-construction sound monitoring campaigns. The advantages and disadvantages of the wind turbine shutdown method will be compared with other methods that don’t require wind turbine shutdowns, such as measuring under high wind shear conditions (low ground wind speeds and high hub-height wind speeds), proxy locations, and wind speed binning.

Who? Ken Kaliski, Principal (RSG)

What? Presentation titled “Challenges in Post-Construction Sound Monitoring for Rural Wind Projects” during the 184th Meeting of the Acoustical Society of America

Where and When? Ken is delivering his presentation on Tuesday, May 9 at 8:45 a.m. ET (7:45 a.m. CT).

2023 New York State Association of Metropolitan Planning Organizations Conference

RSG Director Jon Slason will present during the 2023 New York State Association of Metropolitan Planning Organizations Conference on Tuesday, May 9, and Wednesday, May 10, 2023.

Jon's first presentation, titled “VisionEval – Open Source Strategic Transportation Planning Tool for Long-Range Planning,” will discuss how strategic modeling tools can be employed to understand multiple scenarios as part of the long-range planning process. RSG was part of the original team that designed and implemented VisionEval, and we have since assisted in its implementation across the United States.

Jon's second presentation, presented on behalf of RSG Director Kyeongsu Kim and titled “Online Model Input/Output Analyzer for Visualization,” will discuss an online tool RSG developed to visualize model input and output data, such as socioeconomic (land-use) data and highway network link files. The tool, called Analyzer, provides at-a-glance views of model input data in maps, tables, and charts, making it similar to other visualization tools. The tool also allows users to review and edit scenario input files, including highway and transit network link attributes.

RSG is a proud Copper-level sponsor of the 2023 New York State Association of Metropolitan Planning Organizations Conference.

Who? Jon Slason, Director (RSG)

What? Two presentations, titled “VisionEval – Open Source Strategic Transportation Planning Tool for Long-Range Planning” and “Online Model Input/Output Analyzer for Visualization,” during the 2023 NYSAMPO Conference

RSG experts’ paper on larger wind turbines’ sound levels focus of webinar

RSG's Ken Kaliski (Principal) and Ryan Haac (Consultant) co-wrote a paper with experts from Lawrence Berkeley National Laboratory and Vermont Environmental Research Associates, Inc., titled “Effects of land-based wind turbine upsizing on community sound levels and power and energy density,” on wind turbine upsizing's impact on community sound and power output levels, published in the journal Applied Energy. Their paper will be the subject of a webinar on April 13, 2023, at 1:00 p.m. ET (10:00 a.m. PT).

The team studied larger turbines' effects on micro-siting, power, energy density, and noise. They used desktop software to model larger turbines on two wind development sites and three turbine models representing past, present, and future periods for three manufacturers. The study aimed to maximize the number of turbines and total power output within each site's constraints.

The findings suggest that future larger turbines will lead to fewer turbines per land unit and lower community sound levels, but with increased capacity and energy output.

Key results include:

  • Future turbines are over 60% taller, with 60% fewer turbines fitting in the same land area.
  • Despite fewer turbines, future turbine-based projects have higher capacities and higher annual energy output per land area.
  • Community sound levels at homes will be significantly lower, despite louder turbines.
  • Lower sound levels affect homes near projects and those close to turbines on hosting parcels.
  • Wider adoption of taller, high-capacity turbines will likely yield numerous benefits in the future.
