	%X This research investigates the acoustical characteristics
of Al-Madinah Holy Mosque. Extensive field measurements were
conducted in different locations of Al-Madinah Holy Mosque to
characterize its acoustic characteristics. The acoustical characteristics
are usually evaluated by the use of objective parameters in unoccupied
rooms due to practical considerations. However, under normal
conditions, the room occupancy can vary such characteristics due
to the effect of the additional sound absorption present in the room
or by the change in signal-to-noise ratio. Based on the acoustic
measurements carried out in Al-Madinah Holy Mosque with and
without occupancy, and the analysis of such measurements, the
existence of acoustical deficiencies has been confirmed.
