This paper studies the C80 and D50 objective acoustic indices in relation to source-receiver distance for five different octave bands inside Mudejar-Gothic churches. This type of church, eight examples of which we have studied in the city of Seville, is characterised by good acoustic conditions as far as this can be indicated by reverberation 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 results derived from a semiempirical analytical model proposed.
