Best tool to calculate noise from highway/busy road

Fantastic, if half is blocked by building also can, reduce the view angle

if you stay at 10 floor, height of observer become 10X3 (roughly) = 30m

too complex for me.

Based on the calculator, the noise gets lower as you get higher. However, I've heard the theory (and you have probably as well) that it's actually noisier on the higher floors from agents. Comments?

Too complex for me too.
If unit A is on elevated grounds, unit B on ground level (same as traffic road) n unit C on sunken grounds, the noise level will b greater for A than B than C?

If the sound source is not block , the level Db drop in relative to the distance .

Why some level is more noisy is because the noise is being reflected. And again also depend on the wave length of the noise.

Now back to your question, it really depend if it is block or reflected

as long u understand this diagram, it is not that difficult ... only a few key things are important e.g. the speed of cars, the # of cars in 1 hour, the height of condo units and the horizontal distance from center of road / highway

for the angle of view, if your condo is fully exposed then is 127 degree, if half of them blocked by a high rise building then you have estimate the angle of exposure
