Noise Policy of the flying club will be measured by the means of a Sound Meter using the A weighting response and with the noise meter set to the slow response. It will be up to the club members and persons to measure the sound/noise of most of the models, aircraft, helicopters, etc. No model shall be flown which gives a noise measurement at 7 meters of more than 82dBa.  Should a model be over the above, there are ways of reducing this. In Glow engines, a quieter silencer may be needed, also the propeller may need changing to ensure it’s on or under the recommended figure. On Helicopters, most new kits now come with quiet-pipes or silencers. If they are over the limit reducing the head speed or fitting sound proof material inside the canopy or body can help.

The method of measurement for Aircraft is: working at maximum RPM the model should held 1-2 meters off the ground. The Meter will be some 7 metres from the model. Four readings will be taken. 1 Model pointing at the meter. 2 Model pointing away from the meter. 3 Model at 90 degrs left. 4 Model 90 degrs right. For Helicopters 3 markers are placed on the ground.One central. One at 90 degrs to the left,70 metres from centre,and One  other other 90 degrs to the right.The model should be hovering in ,or on the centre point .Only the two readings are for the above needed.

The club member with the sound meter will take into account any wind on or near the sound meter.All other models including electric models will at the bound by the  above 82dBa procedure. All the tests will be done by one or two or both of our sound meters.
