... • Scheduling -- performance of noisy work during less sensitive time periods • Equipment restrictions -- restrictions on the type of equipment that can be used • Specialty products -- special purpose pads, liners, and enclosures that reduce noise • Noise emission limits -- specification of equipment noise limits 1The Construction Breakout Group members were Cynthia Lee, Proctor Reid, Randy Stanley, Erich Thalheimer, and Jock Whitworth. 2In this context a "receiver" or "receptor" is a human being within hearing distance.

... PATH CONTROLS Path controls interrupt a noise between its source and a receiver. They include: • Noise barriers -- permanent or portable wooden, metal, plastic, earthen, or concrete barriers • Noise curtains -- flexible vinyl curtains hung from supports or draped on equipment

... They include: • Window soundproofing -- installation of double- or triple-pane windows or storm windows • Air conditioners -- window units or a central system • Receptor noise limits -- establishment of cumulative noise limits at receptor locations • Stakeholder meetings -- open dialogue to involve the affected stakeholders and share information • Noise complaint process -- capacity to log and respond to noise complaints • Temporary relocation to hotels -- for use only in extreme, other wise unmitigatable cases As an example of a receiver control, Thalheimer noted that informing stakeholders of work requirements and schedules can increase their tolerance of noise. Information can be provided on a website, in print, in person, or through social media (e.g., Twitter, text messages)

... Reactive measures include use of a noise control plan to observe and inspect the work, enforce limits, and hold contractors accountable. A comprehensive noise specification provides control over the amount of noise generated.
