Quiet Mark is the brainchild of the Noise Abatement Society and has been set up with the intention of encouraging manufacturers to make their machines as quiet as possible – a too-often neglected aspect of design. Machines that bear the Quiet Mark are all significantly quieter than the competition. They are running a competition throughout the 2012 to win approved products – at present the majority are indoor products but a range of approved garden products is available and is sure to grow.
