This standard BS EN ISO/TR 11688-2:2001 Acoustics. Recommended practice for the design of low-noise machinery and equipment is classified in these ICS categories:
- 17.140.20 Noise emitted by machines and equipment
- 21.020 Characteristics and design of machines, apparatus, equipment
This part of ISO/TR 11688 provides the physical background for the low-noise design rules and examples given in ISO/TR 11688‑11) and supports the use of extensive special literature.
It is intended for use by designers of machinery and equipment as well as users and/or buyers of machines and authorities in the field of legislation, supervision or inspection.
Equations given in this Technical Report will improve the general understanding of noise control. In many cases they allow a comparison of different versions of design, but they are not useful for the prediction of absolute noise emission values.
Information on internal sound sources, transmission paths and sound radiating parts of a machine is the basis for noise control in machines. Therefore measurement methods and computational methods suitable to obtain this information are described in clauses 7 and 8 and annex A.
