This second edition cancels and replaces the first edition published in 1992. This second edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: &#8211; an update of Clause 6 to fulfil the requirements of ISO\/IEC Guide 98-3; &#8211; an improvement of the heat conduction theory in Annex A; &#8211; a revision of Annex F: Physical properties of humid air.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Electroacoustics.
