This work proposes a method based on a computer model to assess the economic profitability of energy rehabilitation operations in the envelope of a block of residential dwellings (Virgen del Carmen) in Seville (Southern Spain). The work evaluates the influence that certain hypotheses of interventions in the opaque part of the envelope exert on...

El teatro de la Maestranza es la sala de conciertos más emblemática de la ciudad de Sevilla y fue construido para la Exposición Universal de 1992. Su escenario es muy extenso y flexible en su configuración de acuerdo con el espectáculo a representar. En este trabajo, se ha usado un modelo geométrico-acústico 3D del espacio para analizar las...

The present work consists of a statistical study of the monaural (lateral-reflection fractions and level)and binaural acoustic parameters (inter-aural cross-correlation coefficients) that evaluate the amount ofearly and late lateral acoustic energy encountered in 9 performance halls in Andalusia (southern Spain).Hall volumes range between 6,163...

The paper takes advantage of a recent detailed survey of Spanish Cathedrals to investigate the acoustic differences between choir and other weakly coupled volumes in very large spaces. Experimental measurements carried out in a limited number of source-receiver combinations confirmed the existence of double slope ...

Las instalaciones deportivas en muchas ocasiones se diseñan como un espacio destinado a diferentes usos, debido a esto, el acondicionamiento, el confort y la calidad acústica se hacen cada vez más exigentes. En este caso el propio arquitecto proyectó un espacio polideportivo en Puente Genil (Córdoba) con la pretensión de cumplir con las...

En este trabajo se presentan los resultados experimentales de los parámetros de calidad acústica obtenidos en la capilla del antiguo Hospital de Mora, en la actualidad salón de grados de la Facultad de Ciencias Económicas y Empresariales de la Universidad de Cádiz. El estudio pretende caracterizar su campo acústico con vistas a una posible...

A cripta da Catedral de Cádis é um espaço arquitetónico que devido à sua forma peculiar, uma rotunda abobadada muito deprimida e um conjunto de galerias às quais se pode aceder a partir dela, apresenta um som complexo que é de interesse para análise. Uma das consequências desta complexidade volumétrica pode ser a aparência do...

Entre los edificios patrimoniales que mejor reflejan la identidad cultural europea están las catedrales. Además de las actividades litúrgicas, con la concurrencia de los fieles, en ellas se desarrollan, a pesar de sus largos tiempos de reverberación, otras actividades culturales, con numerosa audiencia, y se han convertido en espacios ...

The theatres of Antiquity, Greek and Roman, constitute public buildings of the utmost importance inthe history of Western culture and in universal cultural heritage. Many of these spaces are being used fortheir original function with or without only minor adaptations. If they are well preserved and/or restored,these performance buildings...

The aim of this paper is to compare two different methods of measuring the Modulation Transfer Functions (MTF) and the corresponding derived STI-RASTI indices to assessing intelligibility. The first method uses, as test signal, a band filtered (500 and 2000 Hz) amplitude modulated noise. The second ...

The bullring of Ronda, one of the oldest in Spain, declared in 1993 as an Asset of Cultural Interest, occupies a paramount place among the buildings of its type thanks to its outstanding beauty. Its configuration as an open-air enclosure with a circular floor plan, as an evocation of the ancient Roman amphitheaters, and its interior with...

This paper studies the statistical correlations between monaural acoustic parameters withthemselves and with architectural parameters from an acoustical survey undertaken in 12Mudejar-Gothic churches in Seville, southern Spain. Objective room-acoustic parameters havebeen measured using impulse response ...

Acoustic simulation methods applied to existing places of worship enable to use calibrated models to simulate the inner acoustic field with enough accuracy. It is possible to obtain adequate spectral and spatial behaviour of the most common room acoustic parameters, and even to obtain simulated impulse...

The Catholic Cathedral of Malaga (southern Spain), located in the historical centre, is the most emblematic building of the city. Its construction began in 1528 and was completed in 1782, suffering several interruptions and modifications at the hands of various architects, and hence various architectural...

The aim of this paper is to facilitate the experimental measurement of acoustic metrics in circular bullrings in accordance with the ISO 3382 standards and to enable the comparison of acoustic measurements and simulations for the various types of bullrings. The proposal analyzes those items in the standard that exert a certain influence on...

Esta comunicación pretende ser una primera aproximación para comparar dos métodos diferentes para medir la Función de Transferencia de Modulación (FTM) y los índices STI y RASTI, de ella derivados, para calificar la inteligibilidad de un canal de transmisión. El primer método utiliza como señal de prueba un ruido filtrado (bandas de octava de...

Las catedrales son monumentos complejos construidos mediante la repetición de volúmenes separados por arcos, bóvedas, columnas..., así como gran variedad de capillas laterales. En el denominado "modo español" el coro se sitúa en el centro de la nave principal y constituye generalmente un volumen más absorbente conectado mediante una apertura...

In this work we have undertaken an acoustic simulation of the sound field in two churches in the historical centre of the city of Seville. The simulation has been carried out through the CATT-Acoustic v7.2f programme, which has been based on the reverberation times measured in those spaces. We ...

This paper studies the C80 and D50 objective acoustic indices in relation to source receiver distance for fivedifferent octave bands inside Mudejar-Gothic churches. This type of church, eight examples of which we havestudied in the city of Seville, is characterised by good acoustic conditions as far as this can ...

This work deals with those acoustics parameters that evaluate the speech intelligibility in eight gothic-mudejar churches in the city of seville. STI measurements 500Hz and 2KHZ central band frequencies are compared with spectral D50 definition indexes at several locations points. Similarly RASTI data are compared to averaged D50 indexes for...

La cripta de la Catedral de Cádiz, es un espacio arquitectónico singular situado bajo su altar mayor y por debajo del nivel del mar. Su emplazamiento, formas, y la piedra de sus acabados la dotan de una acústica peculiar y compleja que resulta de especial interés en celebraciones y actos religiosos y musicales. En este trabajo ...

In Hispania (present-day Spain and Portugal), there are 25 structures documented of classical Roman open-air theatres, of which 10 are in the south, in the Roman Baetica (Andalusia). The Baetica embraced the progress of urbanisation in the time of the Roman emperor Augustus, where theatres, built in stone, were the foci of entertainment,...
