extra GA traffic noticed

The Bay Area has more small plane traffic this week.
I notice more out of state "N" numbers on those planes
flying, creating more NOISE.
It must be the all the bad weather back east causing
all the small planes to fly above me.

Noise is not "created", it's "produced".

Matter and Energy cannot be created or destroyed. Sound is a form of energy,
simply converted from another form of energy.

I don't remember the exact definition of noise, vs sound, but the sound made
by small aircraft is more like music than noise to me.

AVWeb says this is going to be a record year for general aviation.

The two terms are synonymous.

No. Sound is a pressure gradient that moves over time.

All audible noise is sound, but not all sound is noise.

Small aircraft are unusually noisy, compared to their larger cousins. I
believe it comes mostly from propellers, especially when their blade tips
approach transonic speeds, and from engines, which don't seem to have much in
the way of noise-muffling equipment.

Ok daffy,

It really wasn't a great joke, but it would have been moderately funny if
you had not "gilded the lilly" with that NOISE crap.

That's measuring the dollar value of new aircraft sales.

Look at the numbers, and you'll see that sales are a tiny fraction of
what they were in the 1970s.

Maybe if the prices were lower, more aircraft would be sold.

But I suppose airplane manufacterers care about total income, not the number
of aircraft sold.

I guess you just have to be even more rich now to fly than in the past.

Gee, why didn't they think of that? Just make the planes cheaper to make and
they'll sell more!

Do you really think they are selling them at cost now?
