Acoustics and psychoacoustics study of fireworks displays in two different environments: 'Fallas' in Valencia and 'Sanfermines' in Pamplona (Spain).

The different representative manifestations of the culture and traditions constitute the cultural heritage of a people. The globally extended fireworks displays are the visual and sound manifestations of traditions associated with popular culture that must be preserved. The visual component of the castle is not excessively different from one culture to another, but the sound component shows great differences, from the taste for sound power to the search for a practical disappearance of the sound that accompanies it, in direct relation to the cultural component. This paper presents a study of the different soundscapes represented by pyrotechnic fireworks in two traditional festivities in Spain. This paper presents the study carried out on the different soundscapes represented by various fireworks during two traditional festivities in Spain, both UNESCO World Heritage Sites, the Valencia "Fallas" and the Pamplona "Sanfermines", and following the ISO 12913 standard guidelines. Numerous recordings were made for the calculation of psychoacoustic parameters in accordance with the Zwicker models. The similarities and differences of the same event in different locations have been analyzed. Finally, the results of the psychoacoustic parameters have been compared with the subjective responses.
