Loudspeaker Arrangements

Loudspeaker placement has a great impact on the perceived sound in a home theater. Regarding the discussed spatial descriptors, figure 1. shows the performance of several loudspeaker arrangements while producing a recording of different sound fields made in a lecture hall (A), and three concert halls (B-D).

This test was conducted by Muraoka and Nakazato and shows that the commonly used loudspeaker arrangement (i) in home theater surround sound reproduction has an overall good performance in reproducing sound fields and moreover the recommended arrangement by the “International Telecommunication Union”.

Comparison of frequency-dependent interaural cross-correlation (FIACC) measurements in four large halls (A, B, C, D) with FIACC measurements of reproductions of those spaces through different multichannel loudspeaker arrangement in an anechoic space. The results are expressed as a “square error” computed over the frequency range.

In this post, we examined the arrangement of professional speakers. Items needed to be mentioned to improve sound and increase learning will be published in future posts. These items will pave the way for creating a home theater of the highest quality.

The audio products offered in Saba intelligent systems, which include dolly speakers, Yamaha and Cambridge audio amplifiers, and inacoustic cables with great variety and high quality, make it possible to implement any type of equipment to meet the relevant needs.
