The Devil is in the Details–new article by J. Ehnert in The Construction Specifier

srryherd — Tue, 06 Mar 2012 01:33:10 +0000

Jesse Ehnert discusses common culprits that undermine the integrity of acoustic designs in his recent article in The Construction Specifier, “The Devil is in the Details” (March 2012).

No matter the thickness, size, or rating of a floor, roof, wall, door, or window design, its acoustic performance will usually be determined by its weakest link. Sound leaks and flanking paths can render the best building element acoustically inferior. In other words, it is easy to waste, effort, resources, and money on sound isolating constructions by allowing such sound leaks and flanking paths to diminish and dictate overall acoustic performance.

Steve Ryherd spoke at the Congress for the New Urbanism, CNU 18. The topic of the presentation was “Acoustic Expectations, Health Effects, and Design Techniques in the Urban Environment” and addressed potential challenges faced by designers in densely populated, urban environments.
CNU 18 was held in Atlanta, Georgia, May 19-22, 2010. The congress was organized with the assistance of the Centers for Disease Control and Prevention and the focus was “New Urbanism: Rx for Health Places.” Learn more about the event at www.cnu.org/cnu18/

HUD NAG Studies: Arpeggio Services

srryherd — Tue, 09 Feb 2010 20:57:39 +0000

Arpeggio Acoustic Consulting is experienced at addressing the noise concerns of HUD, and we are adept at performing their required analyses. We offer the following services:
NOISE ASSESSMENT GUIDELINES (NAG) STUDIES approximate the expected noise levels at representative locations on your project site per the HUD Noise Guidebook. We go a step beyond the NAG requirements and approximate the noise levels at all points on your site to give a complete picture of the noise environment.
SOUNDPLAN NOISE MAPS more accurately predict noise levels when the NAG Study shows that noise levels are unacceptable. A SoundPlan Noise Map considers the specific characteristics of your site (topography, shielding structures), and may reveal that the conservative NAG Study overestimates noise levels, 10 dBA or more. As a result, noise attenuation requirements may be reduced for portions or all of your project site, significantly reducing construction costs.
NOISE ATTENUATION PLANS address concerns when noise levels are predicted to be unacceptable. These plans guide you in improving the site’s noise environment, including recommendations for noise barriers and/or noise-attenuating construction.

Resources: EASE & SoundPLAN

Arpeggio has the capability to utilize two computer modeling prediction programs on your next project—EASE and SoundPLAN.

EASE predicts real-world acoustic parameters affecting the built environment. Performance spaces, lecture halls, atriums, and more can be analyzed using mathematical and acoustical algorithms in a 3-D modeling environment.

SoundPLAN predicts environmental noise propagation across terrain and can be used to investigate the effectiveness of potential noise mitigation options. The program is used to analyze environmental noise sources including traffic, rail, and industrial facilities. The SoundPLAN calculation methodology is designed to be consistent with the Federal Highway Administration Traffic Noise Model (FHWA TNM).
