Reducing Noise Leakage

In many cases, machine cabinets can be made into effective soundproof enclosures through simple design changes and the application of some sound-absorbing treatment. Adopting some of the following recommendations may lead to substantial reductions in noise output:

Caulk all unnecessary holes or cracks, particularly at joints. Seal electrical or plumbing penetrations of the housing or cabinet with rubber gaskets or a suitable nonsetting caulk.

If practical, cover all other functional or required openings or ports that radiate noise with lids or shields edged with soft rubber gaskets to effect an airtight seal.
