Industrial
noise calculating program for model airfields |
A great asset in calculating the mean noise level at the front porch of the nearest house |
This neat spread sheet I evaluated from the Dutch Industrial noise guide line and an old BASIC program, can be used to calculate mean noise pressure in dB(A) at the building nearest to the flying field. It covers a semi-circular flight pattern, as well as imposed dB penalty for pulsating sounds |

This
is a very nice little freeware program, that calculates the centre of gravity
for any wing planform, along with the needed visual basic runtime libraries,
which must be in your windows/system directory |
