Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for
which a technical committee has been established has the right to be
represented on that committee. International organizations, govern-
mental and non-governmental, in liaison with ISO, also take part in the
work. IS0 collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an lnter-
national Standard requires approval by at least 75 % of the member
bodies casting a vote.
International Standard IS0 9053 was prepared by Technical Committee
ISO/TC 43, Acoustics.

Introduction
The airflow resistance of porous materials indicates, in an indirect
manner, some of their structural properties. It may be used to establish
correlations between the structure of these materials and some of their
acoustical properties (for example, absorption, attenuation, etc.).
This International Standard is, therefore, useful for two purposes:
a) in relating some of the acoustical proper-ties of porous materials to
their struct ure an d their method of manufactu re;
b) in ensuring product quality (quality control).
