    Noise damping.

    I use small discs of wet suit neoprene under the feet of my Mazzer Mini to almost eliminate noise transferring to the bench top which acts like a sound board, works very well when the neoprene is new, however over a period of weeks the rubber compresses and stops doing its job, any thoughts on a longer lasting alternative?

    There are lots of industrial-quality vibration absorbing mounts available. I'd imagine you can get these from a local supplier.

    Thanks for the reply with info Andy, apologies for not getting back earlier, other things happening this week.

    Will chase up mounts when next in the big smoke, for the time being have doubled the neoprene under existing feet, has made a remarkable difference to the noise level.

    How about just spreading the load on the neoprene so it doesn't compress as much? You could simply make a sandwich of the neoprene between the bench and a new top board on which your grinder would sit. Or alternatively if it's too "hard" like that, put some flat disks under each of the feet (disks larger dia than the feet).

    A method I've used successfully is to make a sandwich of materials, e.g. glue a layer of cork onto a layer of rubber followed by a second layer of cork. The cork helps spread the load and protect the rubber, and the rubber absorbs much of the vibration.

    I mostly use a manual grinder that gives out nothing but a low level of sound of the beans breaking up.

    You could try some of the "Silicon" material that they make the heat proof pot stands (trivet ?) from.

    My Rocky grinder is almost silent ...until i put some beans into it !
    ..still trying to eliminate that amplification of the grinding sound !

    Biggest improvement i made was to change to a grinder (K3) that i could use with the hopper removed ( impossible with the rocky), and single dose weighed beans straight into the grind chamber...with a cap to prevent 'popcorning" .
    The hopper was acting like an amplifier if it was not full.

    Looks like we have covered the vibration on the bench and some ideas with the hopper.

    Is there anything that can be used to reduce the actual grinding ????

    I've thrown a doubled over hand-towel over the top of a grinder before which makes a big difference for those 'don't wake the kids with your pre-dawn coffee before your motorbike ride!" mornings. Oven-mit? Doesn't look stylish, but would do the job. Most of the grinding noise comes out the top of the hopper…

    I use a wool Beanie over my hopper - keeps the light out too!

    Ifound a small plastic spice container that fits neatly inside the hopper socket. Filled with sugar it weighs ~ 100gm and acts like a weighted piston to "feed" the 20gm dose in quietly.
