Well, I think it is same as church bell unless bedug has sound like
dug, dug, dug….
Bedug is known as a tool in mosque used to call moslem to pray. It is made from big wood. Its center is hollow so that it make one big cylinder. The front of bedug is covered with animal skin as a membrane to produce sound. As I remember, commonly the membrane is come from goats skin
In order produce sound, we have to hit the membrane so hard. It will produce heavy and low tone sound, but the sound of bedug can be heard even if from far distance.
Well, bedug is one unique thing in Indonesia.
