So Similar, So Different: Diving in the Physical and Acoustic Features of Two theatres. A Case Study

[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.Pérez-Aguilar, B.; Quintana-Gallardo, A.; Llopis Reyna, A.; Guillén Guillamón, IE.

Acústica arquitectónica y urbanística

El objetivo del libro ACÚSTICA ARQUITECTÓNICA Y URBANÍSTICA es el de desarrollar de forma sencilla, en base a unos principios físicos fundamentales, las teorías que en acústica se utilizan, tanto en edificación como en urbanismo. Su contenido se organiza en cuatro secciones , la primera de ellas desarrollada en los cuatro primeros capítulos, establece los conceptos y teorías físicas necesarias para tratar las magnitudes que intervienen en el campo acústico, así como la percepción de las mismas por el mecanismo auditivo humano. La segunda, que comprende los capítulos del quinto al décimo, expone las técnicas y métodos que usualmente se utilizan en el acondicionamiento acústico de salas. Del capítulo once al catorce se plantea la problemática del aislamiento acústico, tanto a ruido aéreo como a impacto, abordando sus soluciones de forma más directa mediante expresiones, algunas de ellas empíricas, normalmente utilizadas en este tipo de intervenciones. Finalmente los dos últimos capítulos se dedican a temas de acústica urbanística, en las que se incluye la evaluación del impacto ambiental.

Using Wireless Sensor Networks and Trains as Data Mules to Monitor Slab Track Infrastructures

Recently, slab track systems have arisen as a safer and more sustainable option for high speed railway infrastructures, compared to traditional ballasted tracks. Integrating Wireless Sensor Networks within these infrastructures can provide structural health related data that can be used to evaluate their degradation and to not only detect failures but also to predict them. The design of such systems has to deal with a scenario of large areas with inaccessible zones, where neither Internet coverage nor electricity supply is guaranteed. In this paper we propose a monitoring system for slab track systems that measures vibrations and displacements in the track. Collected data is transmitted to passing trains, which are used as data mules to upload the information to a remote control center. On arrival at the station, the data is stored in a database, which is queried by an application in order to detect and predict failures. In this paper, different communication architectures are designed and tested to select the most suitable system meeting such requirements as efficiency, low cost and data accuracy. In addition, to ensure communication between the sensing devices and the train, the communication system must take into account parameters such as train speed, antenna coverage, band and frequency
