    The Acoustic and Cultural Heritage of the Banda Primitiva de Llíria Theater: Objective and Subjective Evaluation

    [EN] La Banda Primitiva is one of Europe's most notable symphonic civic bands. Located in Ll & iacute;ria (Val & egrave;ncia, Spain), part of the UNESCO creative cities network, its theater was designed by Joaqu & iacute;n Rieta, one of the most relevant Valencian architects of the twentieth century. This study analyses the current state of the theater, its relevance to the town's cultural heritage, and how it has evolved over the years in terms of its acoustic performance. The objective is to understand how the theater's acoustics have evolved over the years and to unveil the reasons behind the preference of the regular audience for specific areas of the venue, considering if these tendencies are influenced by tradition rather than the current auditory experience. The theater's acoustics were studied with objective and subjective parameters. The objective parameters were assessed by conducting on-site measurements and ray-tracing simulations. One hundred and three musicians answered a survey of auralizations to evaluate subjective acoustic parameters. Three musical pieces were recorded in an anechoic chamber and convoluted by the impulse response of the venue at different positions to obtain the auralizations. The results show that the objective acoustic parameters do not differ significantly. Overall, the reverberation time was longer before the renovation. Regarding subjective testing, the sample only shows a subtle tendency (57%) towards preferring seats on the second balcony. For that reason, it can be concluded that there is no evidence to support the claim that the seats located on the second balcony have better acoustics than those in the stalls.

    So Similar, So Different: Diving in the Physical and Acoustic Features of Two theatres. A Case Study
    (European Network of Heads of Schools of Architecture, 2021-08-05) Pérez Aguilar, Blanca Natividad; Quintana Gallardo, Alberto; Llopis Reyna, Ana; Guillén Guillamón, Ignacio Enrique; Departamento de Física Aplicada; Escuela Técnica Superior de Arquitectura; Oficina de Acción Internacional; Centro de Tecnologías Físicas: Acústica, Materiales y Astrofísica
    [EN] The study of the acoustic conditions of Concert Halls, Theatres, and Opera House offers the possibility of understanding better the behavior of those spaces. Many researchers have dealt with the physical and acoustic characteristics of landmark venues that host live performances, but many of them still need to be characterized and studied. The present work aims to perform a comparative analysis of two theatres. We have chosen two theatres with similar characteristics except one, the volume of the main hall in this case: the Olympia Theatre and the Talia Theatre, both located in the city of Valencia (Spain). We want to get deeper into the factors that influence how a certain space sounds. More specifically, the ratios between stage area and audience area. We have collected geometrical data of both spaces, such as room volume, fly-tower volume, audience surface, stage surface, stage opening surface area, acoustical surface area, etc.; and material and architectural detail data to determine the absorption coefficient of the different surfaces of the space. Moreover, we will conduct acoustical measurements surveys in both theaters. To summarize, we will work in a three-axis strategy: geometric, acoustic absorption and onsite analytic data, to evaluate the influence of the different parameters in the acoustic behavior of the room and the relationships between them.
