For most communities, the answer is most likely no. Otherwise no one
would be able to mow their lawn as a lawn mower is listed at something
like ... 40 db or more.. No many low flying aircraft exceed the sound
of a lawn mower, unless they have a two blade prop, a big engine and
are just departing the active..

The 10 db is probably at a specified distance, similar to what a
neighbor would experience. Say 300 feet? While a lawnmower would in
time deafen its rider (I wear earmuffs), the noise level drops off
pretty fast. The same is true of chainsaws.

Your neighbors lawn mower is going to be a lot louder than 10 db even
at the far side of a normal lot.

You have to stop and realize how little 10 db really is.


Because an aircraft overhead is often a direct line to the hearer,
with much less stuff to soak up the sound, it's apt to be very loud at
500 or even 1000 feet. I live under the traffic pattern of a
"tradeport" so I hear a lot of airplane noise, mostly heavy jets.

When I go over here on the way back to the airport I'm usually headed
down hill at close to 200 MPH. When I depart I'm usually still near
full power and not much above 1000 feet. It's certainly noticeable,
but no where near as loud as the neighbors lawn mowers over 300 feet
away...and through the trees. And their lawn mowers are no where near
as loud as some guy's Beagles about 5 houses to the West.

So, I try to be a good neighbor even if I have absolutely no sympathy
to the people near the airport. The VOR 14 to MBS starts near here so
when the big jets are flying that they go overhead. Even the old
DC-9s aren't all that loud and most modern day jets are not as loud as
a Bonanza with a 2 blade prop on take off.

This is a university town, and therefore a loud-party town. The
residents often complain about student parties with the loud-hailers
going in the night, and the police department has a noise-meter
(whatever) which it will loan out to folks trying to make a case. Very
rarely do they succeed. I'll ask for more information about this if
anyone is interested.

I'm relieved to hear it (as it were!). I suppose we notice airplane
engines because they're out of the ordinary. Where I live, highway
noise is out of the ordinary, so motorcycles really bug
me--motorcycles being the one thing apart from sirens that I can hear
from Bay Road.

My houselot is 40 acres, and I can still hear my neighbor's lawnmower.
And of course I can hear the airplanes overhead. Since I am on the
water, of course I can hear all sorts of noise from there--even voices
in boats a mile away.
