Residential sound insulation program
Sound Transit contracted with Jones Payne to provide full turnkey management services associated with the Central Link Light Rail Project, residential sound insulation program. Over 150 residential units qualified to participate in the program. Only habitable rooms with direct in line-of-sight to MLK Jr. Way S. were eligible for acoustical treatment. The program used the Housing and Urban Development (HUD) interior 45 dBA Ldn as the reference value for interior noise level reduction of light rail impacts and WSDOT’s 51 dBA peak hour Leq criteria as the reference value for traffic noise impacts.
