Defines procedures for comparing the acoustical performance of household radio receivers by means of subjective listening tests against a reference receiver. A subjective evaluation may be presented as an average opinion with a standard deviation.

This British Standard gives guidance on the procedures for carrying out and evaluating the results of subjective listening tests for the comparison of the acoustic performance of various types of household or similar sound radio receivers in a controlled environment, to give reproducible results. This standard describes the requirements for the test room, the composition and qualifications of the judging panel, the setting up and test procedure and the method of scoring.

NOTE 1 The use of this standard for the assessment of high fidelity equipment should be regarded as provisional (see the footnote to the introduction).

NOTE 2 The titles of the publications referred to in this standard are listed on the inside back cover.
