Worship places are psychologically evolved in human’s mind, because his unconscious mind manifests evolution differently in such places. Every religion has its concerning style, while Islam and Christianity represent two different blazes in two separate places. Church and mosque are very important worship places and designers try to create a spiritual sense of place for the audience. Whereas acoustic induces the sense to the audience much more better; this paper investigates an acoustic variable in worship places, at reverberation time was selected as main audio measurement parameter. Three mosques in Tabriz pertaining to Qajar dynasty were assessed and evaluated for their specific construction development patterns and deductible module of RT variable and the obtained results were compared with churches and mosques in Turkey, Spain, Portugal and so forth. Thus, the historical records were identified and obtained through descriptive- research analysis style of RT comparison, measurement tools and devices belonged to B&K, Denmark. Obtained results have availed numerical outputs and quality concepts adopted from numerical factors. We concluded that reverberation time of the mosques is lower than that of the churches, and acoustic quality of the mosques is more effective for speech intelligence, although church is a desirable place for music performance and mosque for speech respectively.

Comparing Reverberation Time in West Churches and Mosques of Qajar Era in Tabriz Abbas Ghaffari1* and Seyyed Majid Mofidi2 1Assistant professor of Architectural Acoustics & Architectural Design, Tabriz Islamic Art University, Tabriz, Iran.
Mosques and churches have always been assessed for creating a desirable sense of worship in audience , the author tries to compare acoustic in the two places , hence, pertaining mosques to Qajar reign have definite structure types , they have been constructed almost uniform with the same materials: six historical samples of historical structures of Tabriz Bazaar were selected , all of them divided in three groups based on their volume , just one sample of a group assessed in the case study.
Churches and mosques as well as study the domain of reverberation time is selected to compare the results, so acoustic of Qajar Mosques is evaluated.
Evaluation of Research Results Reverberation time of comparative study of west churches and mosques of Qajar era is based on descriptive analytic literature, and precise calculations of samples evaluation.
Research tools of other investigators are evaluated precise calculation, simulation and survey studies that have been utilized to compare the obtained results to assess reverberation time of the samples with survey tool and manually; numerical comparison and conceptual quality inferences have been more focused.
As mentioned, current paper is going to deduct from field studies on the mosques built during Qajar dynasty in Tabriz, Iran, while studies of other researches on western churches have logically linked reverberation time of these spaces for sound quality evaluation in Islamic and Christianity worship places.
