Scope

This section applies to loudspeakers used in domestic systems and environments. Although all test methods are designed specifically for discrete loudspeakers used to form monophonic, two-channel stereophonic or multi-channel stereophonic systems. But these methods can also be applied to other devices, such as audio equipment and TV sets where the speakers cannot be separated. This section gives recommendations for the establishment, execution and evaluation of loudspeaker listening tests. Although many aspects are still under discussion, this section gives basic guidelines. Of course some aspects may vary from region to region - especially the listening room, which has a lot to do with local architecture. The tests described in this section were carried out in a room similar in size and acoustics to an "average" living room, and given information on the size of the room, the acoustics, the arrangement of the loudspeakers and the position of the listener, and Specific recommendations for environmental conditions. This part describes the test method, including the selection of program material and the requirements for data processing and result presentation. The recommendations in AES 20:1996 may be referred to when using the methods in this section, especially when it comes to the category of subjective characteristics in 7.2.2. Issues related to trial design, trial conduct, and statistical analysis of data are complex and, therefore, only the most basic guidelines are given in this section. It is suggested that in the initial stage of designing the listening test, consult and learn from the suggestions of experts on test design and statistical analysis. Originally adopted for home theater, multi-channel mode is becoming more and more popular. The method described in this section is applicable to acoustic reproduction of any number of channels. Due to the rapid development of this field, only the most basic guidelines are given in this section.
