Comparing Reverberation Time in West Churches and Mosques of Qajar Era in Tabriz

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.
