Does anybody know of a reliable source for sound levels of the various
commercially available motors? We have been requested to keep the volume
down at our launches. Some of the EJ and a few of the F's really kick up a
racket as they fly. So we are trying to figure out which motors we can get
Keep the noise down? How stupid is that? Who told you this? Where do you
The noise is a pretty hefty part of the fun and experience. Also, I can't
imagine any model motor loud enough to actually bother anybody at with
proper distances used.
Don't agree with it, it's just we have a whiny lawyer who owns a house next
to but well outside the confines of a properly sized range. The request came
from the conservation commission who grants us the privilege of flying in a
town park. We are just trying to be good neighbors. One idea was to keep the
really loud stuff until later in the afternoon.
Actually that is a fairly common complaint at active launch sites.
Unfortunately since even wimpy Estes motors produce enough noise to
generate complaints, the solution is not motor selection, but interface
with immediate neighbors.

See if you can borrow a sound level meter. Take it to a launch, get as
close to the whiner's property as you can without entering it, and take
some sound level readings during a launch. The best approach I've seen is
to then express the results (especially to people who won't understand the
significance of the numbers) as comparisons to noise they're likely to be
familiar with, as in, "The loudest rocket launch we measured was XX Db,
which is about the same as a passenger car driving past your house, or
about 1/2 as loud as a bird chirping outside an open window."
Anytime I do something loud, I fire up the leafblower and let it run. If
they're going to complain, it will be about that noise, and it's not one the
cops will do anything about.
Does the lawyer have a barking dog?
It's not selective enforcement by the cops. There are sound ordinances that
are effective for certain times of the day. There's nothing that can be done
about running a leaf blower till they run it past a certain hour. It differs
from city to city. The launch site is a different story because they have a
land owner to keep happy and in tune with the surrounding neighbors.
Here's a radical idea. Hand out fliers to the neighbors inviting them to
watch with free ice-cream for the kids. Ask at the grocery if they have any
sort of donation programs. Couple of clipboards with "we support this
activity" for neighbor signatures. "These neighbors are fine with the
activity, but we will limit the motors to 'x' to keep the one neighbor

Ladies and gentlemen, boys and girls. We have a winner in the let's find a
way to turn our disadvantage into a positive without having to do anything
illegal, immoral, although fattening is up for grabs because tofu hotdogs
are just plain wrong. . Gee Joel, that is a great idea!
Would you like some whine with that 40K cheese?? BTW, your always
talking about serving certain folks if they would just ID themselves;
