Field notes
The described workflow lets users review or edit equipment sound values and inspect the sound path element by element, including ducts, lining, elbows, branches, silencers, and terminals. Its example compares a classroom at NC 36 as designed with NC 24 after attenuation, against an NC 30 target curve across octave bands. The site says projects stay on the user's computer.
