My first project when I joined a local CD manufacturing firm in the early 1980's, was to isolate the in house designed Laser Mastering Lathe from its surroundings.

Although not heavy, the machine was in an upstairs room of an old Mansion resting on a wooden floor. The mansion stood on one side of a valley. While on the other side about a mile away was a dual carriageway. This machine would not only be affected by someone walking across the room, but also the traffic trundling down the dual carriageway.

This latter effect was not found out until after the machine was suspended on springs and fitted with oil filled dash pots. The final solution to the road noise was solved by Dr H, the Brains behind the whole mastering set-up and was done electronically. Although his initial late night fix looked more like a spiders web with dead flies in, (diodes, capacitors and the such like). When the resident Electronic's engineer came in the next morning a proper circuit board was made. The machine continued to work faultlessly afterwards and further clones were made to meet the increasing orders placed with the company

My best regards

Worked in a hanger years ago that was very close to sea level, some states of the tide made it very difficult to open the hanger doors.
