| الملخص (بالإنجليزية): |
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.

| Abstract (Romanian): |
Unul dintre cele mai importante aspecte care trebuie urmărite într-o biserică este ca nivelul sunetelor percepute de auditori să fie unul adecvat. Răspândirea inegală a acestora poate determina probleme de audiţie care pot fi rezolvate doar prin aplicarea unor soluţii de reabilitare acustică. Studiul prezentat a fost efectuat într-o biserică grecocatolică amplasată în oraşul Cluj-Napoca. În cadrul bisericii, analiza câmpului sonor a fost realizată prin metode empirice şi experimentale. Într-o prima etapă a studiului a fost utilizată ecuaţia lui Sabine, prin aplicarea căreia s-au stabilit valorile timpului de reverberaţie, considerat cel mai important paramentru folosit în evaluarea acustică a unui spaţiu. Suplimentar, s-au realizat măsurători ale timpului de reverberaţie, valorile obţinute fiind comparate cu cele admisibile. Pe baza rezultatelor obţinute s-a propus o soluţie de reabilitare acustică în scopul îmbunătăţirii confortului acustic interior. [ABSTRACT FROM AUTHOR] |
