Clarity and Definition in Mudejar-Gothic Churches

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 be indicated byreverberation times. This article aims to supply more data on these values and to explore the dependence of these measurements on receiver position. Finally, the experimental results have been compared with expected resultsderived from a semiempirical analytical model proposed.
