Acoustic evaluation of some churches located in south of Italy

The churches represent a building type acoustically very complex given their dimensions, the reflecting finish materials of the envelope and the volume composition including domes and niches. This paper deals with the acoustic analysis of same churches located in Campania (Italy), under a reverberation perspective other than clarity and speech comprehension. The acoustic measurements have been undertaken according to ISO 3382-1. The speech definition has been assessed in line with the Vatican Council II guidance, based on a good verbal communication to be determined by a balance among all the acoustic parameters. A further evaluation has been made on the acoustic solutions that aim to adjust the measured values to be more suitable for speech comprehension
