Bob Greenheck must have been born in the 20s. The smart consumer knows how to look at about 8 octave bands and pick which fan is best for him/her.
The way we build has a greater impact on our comfort, energy consumption and IAQ than any HVAC system we install.
why/how would a 'consumer' need to evaluate octave band data?
overall values are weighed against a known reference point.
(ref. various human response to sound lit.)
more than enough info, no?
Well why would they want to compare dBA over multiple octave bands and consider exponential differences?
"consider exponential differences"
please explain further.
consider the magnitude of a decibel increase
again, what is wrong with comparing overall levels (dBA)?
is a home owner going to assess tonal emissions with 1/1-octave sound ratings?
Well I just think giving them 8 sets of numbers to compare and deciding if they think rumbling is worse than whining is a little much.
Maybe give them a simple number to use, sort of like how SEER seems easier for them to grasp than COP
good luck getting a home owner to grasp octave band data.
single number ratings are just fine for equipment emissions.
universal and reliable.
still don't get the: "consider exponential differences"
