Standards Australia is not part of government, they do not make laws or regulations. Australian Standards are not legal documents but many, because of their rigour, are called up into legislation by government and become mandatory. This is a decision made by elected governments, not Standards Australia. Standards are also often incorporated into legal contracts.
Sound Pressure
Sound
Sound is vibration transmitted through a solid, liquid, or gas; particularly, sound means those vibrations composed of frequencies capable of being detected by ears.
For humans, hearing is limited to frequencies between about 20 Hz and 20,000 Hz (20 kHz), with the upper limit generally decreasing with age.
