Acoustics - Recommended practice for the design of low-noise workplaces containing machinery - Part 2: Noise control measures (ISO 11690-2:1996); German version EN ISO 11690-2:1996
The document deals with concrete aspects of noise control in workplaces and with categoric valuation of the application of specific noise control measures in certain problems. Noise reduction measures can be applied at source (emission), between the source and the receiver (transmission path) and at the work station (receiver). This standard gives advices for the evaluation of noise control devices and sound insulation measure as well as of the acoustical quantities of workplaces and buildings. The efficiency of noise control measures should be verifiable in situ.#,,#
