I am looking for someone to build a soundproofing enclosure for a pressure pump system. The pump is water cooled, obviously something that enabled simple access would be ideal. Any recommendations?

  1. This is a difficult issue. Large pumps typically emit a low frequency oscillation. How many “pump cycles” per second, sort of thing. The pump would be mounted to spring isolators that are matched to the pump frequency and weight. Very common. Check out Mason Industries.

    After addressing the impact noise, you can much more easily build a shell to hold the airborne noise.

  2. Hey, thanks for mentioning me here edifice rex. I saw this post earlier today and thought about it briefly – and wasn’t going to reply until you plugged me.

    Noise is a real funny thing. The last time I considered helping someone with a noise issue, we got an engineer involved and he said the problem could be solved, but that it was going to be a lot of $$$ (because it was structure borne). The customer decided to let it go.

    Part of the problem is what you mention, structure borne noise. We’ve dealt with that with air handling equipment in commercial buildings and even if we have them on isolation pads (mcmaster carr stocks these if I recall correctly) set on a solid concrete floor, with braided connections, we still need space between the object and the wall that is doing the insulating – or else airborne noise becomes the problem. It is good to have several feet of space – like 4′ to work with around the device. I tried it once with a foot between an air handler and the wall that divided the equipment room from an office, and learned my first lesson in accoustical engineering.

    If this problem simply requires some kind of box with accoustical foam insulation and we do not have to worry about it becoming a fire hazard, I would consider discussing it. It would be very simple to make.

    Feel free to give me a call.

  3. Is it air borne noise or vibrations through the joists? I would first try to minimize the structure borne noise by isolating it with rubber pads or acoustical hangers and then flexible pipe fitting if needed. If it is mostly airborne noise a box with baffles and sound absorbing mats will help. Maybe Steve from the Tinkers Wagon can help.
