Soundproofing noisy gate

[nic_roe@hotmail.com]

We recently had a side gate fitted to the outside of our end of terrace property. It is used regularly by our neighbours in the 10 or so adjoining houses. We have had it sprung as if it were not it would be left open. The trouble is that when it is left to close it slams shut very loudly. I have tried pads but this has not helped. Can anybody suggest any other solutions to our problem?
