✦ Synopsis

Field measurements in 30 mosques in Amman, Jordan are reported; the field measurements include RAST1, reverberation time, background noise lerel EDT and signal to noise ratio. RASTI values range between 0.39 and 0.59 where the articulation index ranges between poor and fair. There is not a sbzgle mosque in which the articulation index is good or excellent; despite the fact that these mosques are costly and their spiritual and functional aspects hat'e received special attention, the reverberation time is, in general high and, in one mosque it was around 27s at low frequency. In the Jordan University Mosque the reverberation time varies between 10 and 4 s. The poor acoustical performance of these mosques is mainly the result of little treatment inside and high background noise due to poor insulation of the building envelope against external noise.
