A summary of two recent ASHRAE research projects in acoustics

Key Points

The research findings focus on how noise can cause annoyance, specifically in relation to building services equipment.
One project examined the annoyance threshold of tones, while the other analyzed insertion loss of duct liners in sheetmetal ductwork.
These projects resulted in comprehensive reports and user-friendly software available for ASHRAE members.
The software helps professionals quickly address acoustical issues related to building design and ventilation.

Abstract

One of the many great things about ASHRAE is its commitment to research. This presentation will focus on two recently completed research projects sponsored by TC2.6 Sound and Vibration: (1) Annoyance Threshold of Tones in Noise as Related to Building Services Equipment (RP-1707) and (2) Effect of Lining Length on Insertion Loss of Acoustical Duct Liner in Sheetmetal Ductwork (RP-1408). In addition to a final research report, each with over 300 pages, these two research projects have also created software programs available to ASHRAE members at no cost that provide quick and easy answers to questions relating to the research. These two software programs will be demonstrated as part of the presentation.
