Acoustics – Noise emitted by machinery and equipment
Provides brief summaries of the basic Standards for determining emission sound pressure levels from all-types of machinery and equipment, at work stations and other specified positions, and gives guidance on the process of selection of which is appropriate to any particular type. The guidance given applies only to airborne sound, and is for use in the preparation of noise test codes, and also for use in noise testing where no noise test code exists. It is important that specific noise test codes for various types of machinery and equipment be established and used in accordance with the requirements of these basic standards. Such standardized noise test codes will give detailed requirements on mounting and operating conditions for the particular family to which the machine under test belongs, as well as the location of the work station(s) and other specified positions as prescribed in these standards. The data so obtained may also be used for the declaration and verification of emission sound pressure levels as specified in ISO 4871.
