ISO 532 - Living and working with alternative loudness standards

摘要: By its very nature, standardization claims to set u nique rules and procedures, thus aiming unique, i.e . comparable reproducible results. Also, be effecti ve, the standard underlying approach need t o broadly accepted by addressed user community. To come up with such general agreement it is typical ly required that a “best” approach, covering all relev ant applications of interest, has been established. If this does not apply, existence alternative standa rds in parallel may offer way out. The revision process ISO 532 “Acoustics ‐ Methods for calculating loudness” showed was possible prove agree on single appr oach. Acknowledging legitimate demand applicative continuity, member bodies TC 43 “Acoustics” therefore decided maintain given situati specifying two approaches again.
