(ST SEV 1930-79)

Instead
GOST 12.1.003-76

By the Decree of the USSR State Committee for Standards dated June 6, 1983 No. 2473, the validity period was established

from 01.07 84

The standard establishes noise classification, characteristics and permissible noise levels at workplaces, general requirements for noise protection at workplaces, noise characteristics of machines, mechanisms, means of transport and other equipment (hereinafter referred to as machines) and noise measurements.

1. CLASSIFICATION

1.1. According to the nature of the spectrum, noise should be divided into: broadband with a continuous spectrum with a width of more than one octave; tonal, in the spectrum of which there are pronounced discrete tones. The tonal character of noise for practical purposes (when monitoring its parameters at workplaces) is established by measuring in one-third octave frequency bands by exceeding the sound pressure level in one band over the neighboring ones by at least 10 dB. 1.2. According to time characteristics, noise should be divided into: constant, the sound level of which for an 8-hour working day (work shift) changes in time by no more than 5 dBA when measured on the “slow” time characteristic of a sound level meter according to GOST 17187-81; intermittent, the sound level of which during an 8-hour working day (work shift) changes over time by more than 5 dBA when measured on the “slow” time characteristic of a sound level meter according to GOST 17187-81. 1.3. Intermittent noise should be subdivided into: fluctuating in time, the sound level of which changes continuously over time; intermittent, the sound level of which changes in steps (by 5 dBA or more), and the duration of the intervals during which the level remains constant is 1 s or more; impulse, consisting of one or more sound signals, each with a duration of less than 1 s, while the sound levels measured in dB AI and dBA, respectively, on the time characteristics of the "impulse" and "slow" sound level meter according to GOST 17187-81, differ by at least 7 dB.

Where p is the mean quadratic value sound pressure, Pa; p 0 - original value sound pressure. In air p 0 = 2 ´ 10 -5 Pa. Note. For an approximate assessment (for example, when checking by supervisory authorities, identifying the need for noise suppression measures, etc.), it is allowed to take the sound level in dBA as a characteristic of constant broadband noise at workplaces, measured on the “slow” time characteristic of a sound level meter in accordance with GOST 17187-81 and determined by the formula

where r A- root-mean-square value of sound pressure, taking into account the correction "A" of the sound level meter, Pa. (Revised edition, Rev. No. 1). 2.2. A characteristic of intermittent noise at workplaces is an integral criterion - the equivalent (in terms of energy) sound level in dBA, determined in accordance with reference Appendix 2. Additionally, for time-fluctuating and intermittent noise, the maximum sound levels in dBA measured on the “slow” time characteristic are limited , and for impulse noise - the maximum sound level in dBA I, measured on the time characteristic "impulse". It is allowed to use noise dose or relative noise dose as a characteristic of intermittent noise in accordance with reference Appendix 2. 2.3. Permissible sound pressure levels in octave frequency bands, sound levels and equivalent sound levels at workplaces should be taken: for broadband constant and intermittent (except for impulse) noise - according to the table;
