Measurement of the Level of Speech Intelligibility and Other Acoustic Parameters in the Calvinist Church in Kalinčiakovo

The Calvinist Church in Kalinčiakovo belongs to the most significant cultural monuments in Slovakia. Its history reaches back to the first half of the 12th century. Originally it was a Roman-Catholic church consecrated to St. Ann. Today it belongs to Calvinists and church services take place in it regularly. The speech intelligibility during the church services is the key acoustic parameter of churches and its level can be measured and expressed via two parameters – Speech Transmission Index (STI) and the rate of speech clarity C50. The measurement was realized for various microphone positions with a number of audio sources placements with regard to the usual places from which the speeches are given. Apart from the parameters for speech intelligibility also other acoustic parameters were measured in the Calvinist Church in Kalinčiakovo necessary for the evaluation of the space from the aspect of its suitability for musical productions
