This draft of Standard 62.2 focuses on a key issue from prior reviews. For the 2nd review the sound rating for intermittent exhaust fans was set at 1.5 sone maximum. In response to commenters in the home building industry, the requirement was limited to kitchen fans in the 3rd review. It has now been found that building a 1.5-sone fan is more costly than previously thought, so this draft proposes a requirement of 3 sone for both kitchen and bathroom fans. Fans larger than 400 cfm are exempt.
