THE ALLOWABLE LEVEL OF NOISES TENTATIVELY ACCEPTED IN 1953

Actually high signal-to-noise ratio is only needed, however, for radio listeners to enjoy pleasant listening, regardless whether a noise level is larger or not beyond the allowable level. Therefore there is no harm to radio listeners in vicinity of the large cities even when the noise level is beyond 40 dB, but there is complaint for noises in the secluded place among the mountains even in the case of low noise below 40 dB. The level has been practically fixed to make clear the action which should be taken by railway administration for the broadcasting services in reducing the noises.
