| Abstract | |
Acoustic parameters are the criteria that define the acoustic quality of a music hall. The musical audition inside a room is influenced by a group of acoustic impressions that occur at the same time. Each one of such impressions is associated with a particular subjective parameter that is correlated to a measurable physical value. These values are taken as a set of objective parameters that constitute a scientific basis for the acoustical analysis of a music hall. In this work we have conducted both a theoretical and an experimental investigation on the analysis of the most important acoustic parameters for the evaluation of the quality of a music hall. Also, we have done an extensive research on the related bibliography to support our measurement procedures and formal conclusions. We have implemented the necessary technology to obtain the acoustic parameters. We also have determined the most efficient experimental methodology to carry out acoustic measurements and we have applied this methodology to the measurement of six important concert halls. Then we have compared the data related to each hall and performed a critical analysis of this data, increasing our understanding on the meaning and the usefulness of the acoustic parameters. Finally, we have made a subjective jury analysis, correlating the measured acoustic parameters to the impressions about music samples recorded into those concert halls. (AU) | |
