Our research found that when sports fencing had been installed, after a while of consistant and repetative hitting of a ball against a fence, the fence bolts would gradually become looser, creating rattle and considerable noise when being struck by a ball. This could be very noisy for neighbours nearby.
Zaun’s solution to MUGA Noise Reduction is simple, use small EPDM inserts in between the clamp bar and post, which eliminates the rattle noise when a ball is struck.
Zaun performed noise analysis tests on our standard Duo Sports fencing system, with fixings at every 200mm. The test was completed by propelling a football at a fence, from a distance of 2 metres on four separate occasions.
These tests were undertaken in natural sound with a basic reading of 40-50db of sound, using a mini sound level meter. These readings we taken by placing the noise device at a distance of 300mm from the fence panel, positioned in line with the post.

As you can see from the results table above, this is circa a 29% improvement – however the dB scale is not linear, so 66dB is roughly equivalent to talking 1m away or a car travelling on a street. The 93dB is roughly equivalent to a heavy truck passing.

MUGA Noise Reduction can easily be achieved with the use of EPDM inserts behind the clamp bar. All Zaun Sports Fencing Systems are now supplied with EPDM inserts included as standard.
