EQ Credit: Acoustical Performance - Needs cleaning

If someone else has not submitted a comment, I have more than I submitted (one per credit per person and cannot edit!) 1. suggests a noise range must be met. The 'range' was meant to be a range of design goals (maximum noise level to meet in design) for the type of space. It was not meant as a performance spec for noise measurements, or a minimum noise level. The idea was that for some projects higher design goals are acceptable, and others quieter goals are required than the stated goal. Thus +/- 5 dB. I submitted a comment on this. 2. Not clear if room sound levels have to be measured or merely designed and calculated. My view is one or the other but not both. "Measurements for room sound levels shall be measured using a sound level meter that..." could be interpreted you have to measure noise levels, but I think it was intended to tell you how you have to do it if you do it to show compliance. I also think compliance should be no more than 5 dB above the stated maximum design goal. It is also not clear on what type of measurement technique must be used (room sampling, background noise, different flow conditions etc...). 3. It appears it is specific that you need to show you meet the HVAC noise level via path calculations, but again I wonder if this was one of two ways to comply. 4. work is underway in 189.1 and international green building code for similar requirements... I am sure this will continue to develop as this is the first time such an extensive effort has been made to add acoustics to all building types.
