Vietnamese Standard TCVN 7192 - 2 : 2002 - Acoustics - Rating of sound insulation in buildings and of building elements - Part 2: Impact sound insulation

This document aims to finalize the data in standards TCVN 7192–1 (ISO 717–1) and TCVN 7192–2 (ISO 717–2) because such data is not entirely accurate and leads to different interpretations of the obtained data, especially when performing digitalization in computer software.

This amendment and supplement to standard TCVN 7192–2 (ISO 717–2) defines the procedure for evaluating the weighted impact sound pressure level reduction when floors are covered with lightweight material layers, providing more accurate instructions and introducing the following minor changes in subsequent parts of the standard:

– updating normative references;

– changing the first paragraph of Clause 4.3.1, Measurements in one-third octave bands and adding a new footnote 1 at the bottom of the page;

– changing the first paragraph of Clause 4.3.2, Calculation of spectrum adaptation terms and adding a new footnote 1 at the bottom of the page;

– after Clause 5, adding a new Clause 6 describing the method for evaluating the weighted impact sound pressure level reduction when floors are covered with lightweight material layers;

– amending Annex A;

– amending Annex B;

– amending Annex C;

– Deleting "Annex D", deleting the title "Bibliography" and the list of references.
