I remember a few years ago more loudspeakers were put up in various places around and about. Several Turkish friends I know expressed fury at this... One even disabled the one outside his window.
Anyone that doesn't live here full time and rents somewhere for a holiday may have difficulty adjusting to a loudspeaker going off right in their ear. People want to be able to relax, stay up late, get up late not wake up to an alarm etc. it's quite understandable, pretty crap for you though danemmi...
When you live here, I have found you just get used to it and tune it out. It's one of the reasons that burglaries are often timed to coincide with the early morning call to prayer because our subconscious is already used to hearing and tuning out noises at that time.
