Characteristics of modern digital sound sources for room acoustical measurement
Liu Hai-sheng · Shengxue jishu · 2003
In this paper, three types of typical digital sound sources, pseudonoise, linear sweep, and impulse-shaped signals, are analyzed. Their common advantages and individual characteristics are described. Pseudonoise is a common source, while sweep is more advantageous in practical applications due to its simple operation principle. If reverberation time of room is long enough, influence of the loudspeaker response on measurements is negligible.
