Abstract
THE Leningrad Institute for the Protection of Labour is doing much useful work in combating the noise of machinery in Soviet factories. Some two hundred silencers of special design have been fitted to the automatically driven lathes of Leningrad factories manufacturing electrical apparatus. It is claimed that these silencers reduce the noise of the machines to the loudness of the normal human voice. The Institute is also carrying out experiments to reduce the noise of machinery at other types of works and factories and on the mot or-ships of the Black Sea. During the past year the Institute has received more than twenty different designs for silencers from Soviet engineers and factory workers.
