  • Abstract
    Tests indicate that by proper application of sound-absorbing materials in electric machines, it is possible to obtain noise reductions of the order of 5 to 10 db. If economy is not a factor, greater reductions can be obtained, although the law of diminishing returns sets in rapidly.
