ISO 22234:2005

Cinematography — Relative and absolute sound pressure levels for motion-picture multi-channel sound systems — Measurement methods and levels applicable to analog photographic film audio, digital photographic film audio and D-cinema audio

ISO 22234:2005 specifies the measurement methods and wide-band sound pressure levels for motion-picture control rooms, review rooms, and indoor theatres. Together with ISO 2969, it is intended to assist in standardization of reproduction of motion-picture sound in such rooms.

Cinématographie — Niveaux de pression sonore relatifs et absolus pour les systèmes de films cinématographiques sonores multicanaux — Méthodes de mesure et niveaux applicables aux films sonores photographiques analogiques, aux films sonores photographiques numériques et à l'audio de D-cinéma

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
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, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 22234 was prepared by Technical Committee ISO/TC 36, Cinematography.
