Реферат: What simulated organ music usually lacks, partic. in the region, is adequate spatial coupling between the electro-acoustic transducers and the surrounding air. A mere increase in audio intensity cannot make up for this lack because it would overemphasize the impression of a one-dimensional source of the music and moreover, tends to overload the transducer in the preferred frequency ranges which still the output. To overcome this a loudspeaker is assigned to a series of tuned , such as pipes, there being twelve in each octave, pref. in an indoor environment with controlled temp. The fundamental of a tone as well as all the harmonic components are individually amplified by the appropriate resonance cavities so that a relatively very large air volume linkage exists with the auditorium. The cavities may consist of thin-walled plastics pipes. of 8 to 15 cm diameter.
