David Towers, speaking at APTA's 2008 Rail Conference
David Towers, a Principal Engineer in HMMH's Rail Services Group, is speaking at APTA's 2008 Rail Conference. Mr. Towers' presentation, "Assessing the Noise Impacts of Rail Transit Projects in Shared Use Corridors Using the FTA Guidance" is part of the June 4th Session: Resurgence of Vibration & Noise Problems in Shared Use Corridors -- New Perspectives & Solutions.
APTA's 2008 Rail Conference is schedule for June 1-4, in San Francisco, California.
Christopher Menge and Jack Freytag, Presenting at Noise-Con 2008
Christopher Menge, Senior Vice President at HMMH, will be presenting at Noise-Con 2008 (Session 8.1 – Recreational Noise). His presentation will include a case study on Shenandoah Speedway, a new racetrack facility for which HMMH performed noise analyses and implemented strategies that successfully addressed both community concerns and the economic interests of the track owner.
Jack Freytag, Director of HMMH's southern California office, is giving a presentation on residential sound insulation at Noise-Con 2008. His paper describes the methods for measuring the overall noise level reduction of rooms within an airport neighborhood residence from aircraft flyover noise. The results from applying the various test methods on a single residential structure are presented and evaluated. The paper will also be presented at TRB's summer meeting of ADC40 in Key West, FL.
Noise-Con 2008 is scheduled for July 28-31 in Dearborn, Michigan.
HMMH is assisting the University of California
HMMH is assisting the University of California, San Francisco to determine the noise effects from expected helicopter operations to and from the rooftop helipad, which is included in the proposed Medical Center at Mission Bay, San Francisco. UCSF recently held a community workshop where the noise study results were presented: http://pub.ucsf.edu/today/cache/news/200804071.html.
Article ‘Challenges and Promises in Mitigating Transportation Noise'
The Fall 2007 issue of The Bridge, published by The National Academy of Engineering, addresses the most current issues of noise as a technological and policy challenge. The subject of transportation noise was discussed in an article titled ‘Challenges and Promises in Mitigating Transportation Noise'. The article was co-authored by Dr. Carl E. Hanson of HMMH, along with Professor Ian Waitz of MIT and Dr. Robert Bernhard of Notre Dame University.
Citing the widespread nature of the problem, "There are only a few places in the United States where transportation noise is not noticeable" the authors proceed to summarize the problems and promising solutions of noise control for the aviation, highway and rail transportation modes.
The article was written in conjunction with Dr. Hanson's work with the National Academy of Engineering study committee on "Technology for a Quieter America." The committee is charged with investigating the economic and quality-of-life benefits of controlling excessive noise in workplaces, communities and homes. During the study, the committee will be reviewing existing engineering solutions and identify potential solutions and recommend policies that could advance their development and deployment.
Sheffield Wind Project Approved
The Vermont Public Service Board approved UPC Wind's proposed 40 megawatt Project in Sheffield, Vermont. Harris Miller Miller & Hanson Inc. (HMMH) assisted UPC Wind in minimizing the environmental noise impacts on Sheffield communities.
Mr. Christopher J. Bajdek, Senior Consultant at HMMH, led the noise analyses. "...HMMH is pleased at the outcome and feels confident that the needs of all stakeholders were met," said Mr. Bajdek.
The following is an excerpt from the final decision regarding noise limits imposed on the project: "UPC shall construct and operate the Project so that they emit no prominent discrete tones pursuant to ANSI standards at the receptor locations identified infindings 189-194, and indoor sound levels at any King George School structure and any surrounding residences do not exceed 30 dBA (Ldn)."
With 25 years experience, HMMH is an industry authority, offering a range of noise-related services, including environmental impact statements, site evaluation, criteria selection, compliance testing, and public involvement for the power industry.
