Musical acoustic analysis: The influence of the source's directivity on the parameters which describe closed spaces with an intended purpose: The listening of chamber music and symphonic music

An acoustic analysis for particular closed spaces (concert halls, churches, etc.) is offered in this work. The analysed spaces have different architectonical typologies but they are finalised to the same utilisation: the listening of chamber music and symphonic music. To simulate the behaviour of the orchestra this analysis employs sources which describe the directional characteristics of each musical instrument. To show the synergy between each of these sources and the closed space, several scenarios have been employed; in this way we are able to characterize the specific musical atmosphere created by each instruments. This work suggests a method to investigate the effects of the instruments' directivity, in relationship with the considered frequency, on the musical performance of he considered space. It also represents an example how it could be possible to build a knowledgebase which relates close space design acoustical parameters to musical instruments typologies according to chamber music or symphonic music.
