Indonesian officials are trying to regulate the volume of loudspeakers from 800,000 mosques across the world's most populous Muslim-majority nation once again, with every year during Ramadan the noise leading to complaints from the public.
A team has been formed to investigate complaints and to take samples of noise from mosque speakers across the country.
The team's spokesman Husain Abdullah told AFP that the aim is to create a "more harmonious, melodious sound coming from mosques."
"The idea is for mosques to turn down the volume a little so that the sound can be heard only by residents in the immediate area," he said.
Indonesia’s vice-president, Jusuf Kalla, will discuss the findings and possible solutions with the country's top Muslim clerical body after the team sends its report.
Abdullah criticised a “loudspeaker war” between local mosques which have been setting volumes too high. His team has found that mosques also issued the call to prayer at different times and undertook sermons at hours there shouldn't be any, he told BBC.
"They should agree on the time and duration. Say for the morning there's a prayer for 5 to 7 minutes, then the call to prayer. That's enough. Don't broadcast a prayer loudly from 4 o'clock in the morning," he said.
The new team is intended to complement a previous initiative which has tried to give advice on how best to reduce noise created by loudspeakers, AFP news agency reported.
