Opis:
The article presents the course and the results of an experiment, which aimed at the subjective assessment of the multi-channel impulse responses. The assessment was conducted considering the usefulness of the received responses for the conducting operation of the digital convolution. The resulting sound material is generated for the simulation of the characteristics of the room. In a medium-sized, rectangular reverberation room (74 $m^3$) a number of measurements of impulse responses were conducted with the use of multi-channel microphone techniques and with the use of SoundField type microphone. In identical conditions the raw sound material was recorded (in conditions of free field). Next, the convolution was performed between the raw material and the recorded impulse responses. The group of experts, whose members had at least 5 years of experience in the field of sound engineering, was subjected to the psychoacoustic tests aiming at comparison of the sound materials achieved in the convolution and in the recording.

Opis:
There are many objective parameters of the room impulse response which we can calculate that describe its acoustic field. The room impulse response can also be used to provide listening tests using the convolution technique. The aim of this work is to consider the influence of the impulse response measurement chain on objective numerical parameters and on the subjective perception of listeners. This article shows the impulse response measurement results obtained in the reverberation room using not only commonly known measurement chain elements but other elements, too. Standard components such as an omni-directional source and measurement microphone, as well as a consumer active loudspeaker and various audio recording stereo microphone pairs were used. The results are compared taking into consideration calculated numerical parameters and the application of calculated impulse responses to subjective listening tests. To determine the applicability of impulse responses to psychoacoustic listening tests, a preliminary listening test using headphones was carried out on a selected group of listeners. The audio test material consisted of samples of choral music and speech recorded in an anechoic room and convolved with previously analyzed impulse responses. This article shows how big the differences of subjective listener feelings are for different acoustic transducers.

Opis:
Direct and ambient sounds are usually reproduced through the same loudspeakers. In multichannel systems, with the use of anechoic recordings and auralization techniques it is possible to separate these sound components so that they are reproduced via different loudspeakers. Four basic options of management of direct and reflected sounds were investigated in a perceptual experiment. One sound source and the standard 5.0 surround sound system was used. It was found that listeners consistently preferred sound reproduction with direct sound radiated from only one loudspeaker.
