Author: Hany Hossam Eldien

Abstract ID: 3328

Working in Architecture design studios environment requires various activities. Interaction, communication and meetings could affect the speech intelligibility and the speech privacy conditions. Students Areas with a more silent environment are needed with a minimized level of distraction from surrounding activities, while teamwork and discussion areas with a high level of interaction need a good speech intelligibility. One of the more important elements which can improve the open spaces acoustical conditions is the partitions between workstations.The main purpose of this work is to evaluate the acoustical performance of four partitions types in open plan offices; 1.10m two sides partition height, 1,50m front side partitions, 1,50m one side partitions and 1.50 two sides partitions. This Study was conducted in the College of Architecture, Imam Abdulrhman Bin Faisal University, KSA.  Based on ISO 3382-3, Speech Transmission Index, STI in the nearest workstation, Distraction distance rD, privacy distance rP, A-weighted background noise level L,A,B and A-weighted SPL of speech at 4 metres L,A,S,4m have been measured. It was found that the best results can be obtained by 1.50m front side and 1.50m two sides partitions.

Noisy Motorcycles and Barriers and Quieter Pavements for Traffic Noise Abatement: Summaries of Two TQA Workshops
Time: 11:40 am

Author: Paul Donavan

Abstract ID: 2611

In the Technology for a Quieter America report, motorcycles were mentioned three times, once in terms of standard test methods and twice in relation to community noise. In New York City, motorcycles placed in the top 10 bothersome noise sources identified by residents. Although there are regulated levels that manufacturers must meet, complaints about in-service motorcycle noise persist. To address this issue, a round table meeting was held in August 2012 with a broad spectrum of participants representing manufacturers, regulators, and other interested, knowledgeable engineers. In preparation of the TQA report, a workshop entitled Cost-Benefit Analysis (CBA) for Noise Control found that CBA was being applied in the area of traffic noise mitigation in regard to the use of barriers and/or quieter pavement. To address the particular CBA issues for this topic, a workshop was held in January 2014 with state and federal transportation officials and the research team responsible for the National Cooperative Highway Research Program NCHRP Report 738, Evaluating Pavement Strategies and Barriers for Noise Mitigation. The findings of these two meetings are summarized in this paper.

TQA-1: The 2010 NAE Technology for a Quieter America (TQA) report and ten years of workshops
Time: 12:20 pm

Author: Eric Wood

Abstract ID: 2893

The Technology for a Quieter America project began in February, 2005 with a request from the project office of the National Academy of Engineering to produce a consensus report on the state of the technology in noise control engineering. A committee was appointed and a series of workshops on the various TQA topics were held. The TQA report was published by the National Academies Press in 2010. After the report was completed, it became clear that additional studies on specific topics covered in the TQA report would be valuable. These were not to be traditional consensus studies but workshops organized on an ad hoc basis and approved by the NAE project office. The first workshop was in 2012 on noise from motorcycles and the most recent workshop held in 2020 was on aerial mobility which included drones and air taxis. In all, ten reports have been published and are available as public information documents from the Institute of Noise Control Engineering. In 2016, the National Academy of Engineering formalized the process for development of workshops in the form of member-initiated activities. There is currently a formal process for the submission and approval of proposed projects.
