Explanatory note
This note is not part of the regulations, but is intended to indicate their general effect.
These regulations remove out-of-date references to base-line hearing tests, replace a reference to a standard for audiometric test methods with a reference to a new standard, and substitute the current table for age-related hearing loss with a more recent one that comes from the National Acoustic Laboratories (NAL) Report No 118, January 1988, Appendix 5.
The provisions relating to the new standard come into force on 1 January 2012 and the rest of the regulations come into force on 1 January 2011.
