摘要

A common practice in the execution of listening tests is to choose the sound reproduction system based primarily on its availability, with little regard for its potential influence on the results of such tests. To examine the magnitude of this influence, a methodology is proposed and a tool is developed for presenting sound samples through different sound reproduction systems. The tool is equipped with a user interface that enables easy and seamless change of the sound reproduction system, as perceived by the listener. The design of the tool eliminates the need for any kind of intervention that would interrupt the listening session, such as on-the-fly system reconfiguration or calibration. The goal is to achieve interchangeability between binaural reproduction using headphones and 3D Ambisonics reproduction using a multichannel loudspeaker system as a typical spatial audio reproduction system. However, the extension to two-dimensional amplitude panning systems such as stereo or 5.1 surround is considered as well. The software design of the tool is based on Cycling '74 Max programing language. The tool is to be used in listening tests focused on the subjective evaluation of overall acoustic comfort, in relation to the quality of sound insulation in closed spaces and their room-acoustical properties.
