Abstract text:
One of the most important aspects aimed within a church is focused on the capacity of congregation members to hear sounds at an agreeable level. The uneven spread of the sounds throughout the area occupied by the auditors may cause audition problems that can be solved through acoustic rehabilitation solutions. This paper presents a study of a Greek-Catholic church located in Cluj-Napoca. In the church, the analysis of the acoustic field was made both by using empirical and experimental methods. As a basic study of the room acoustic, the behavior of the sound propagation was determined by using the Sabine equation. By applying it, the values of the reverberation time, which is the most important parameter currently in use for the room acoustic description, was established. Also, for a complex study of the reverberation time, acoustic measurements were developed, the resulted data being compared with the admissible one. Therefore, following the obtained values, a correction solution has been proposed in order to achieve the needed acoustical comfort through a judicious dimensioning of the reverberation time.
Key Words:
church; reverberation time; Sabine equation; acoustic measurements.
