I think they are bread in captivity, it is those OFW's and young sexy ladies who keep escaping and breeding in other parts of the world....
Have to agree. Noise here will probably be as much of an issue here as most other places in the Philippines. The good thing about Dumaguete is that because of it relatively small size 15-20 minutes outside the downtown core you are in the rural areas. All you will have to do is some "ears on" due diligence to ensure you don't move in next to a the local rooster farm or videoke hangout. and ummm,,forget about the authorities understanding, let alone enforcing any of the noise bylaws that exist. No need to add frustration to you woes.
Just as another anecdote, my own home is delightfully quiet both day & night these days -- in Bacacay, southern Dumaguete, probably quite near Alex who posted back at the beginning of this thread. Some dog yapping, but currently no roosters (temporary i'm sure), few motors, never a music-blaster as you describe except perhaps on holidays. In all probability this is just only my (current) good-fortune, however; I can't imagine that it has ANYTHING to do with laws or my neighbors obeying them. I "knock on wood" as i write this... someone might buy such a system as you depict any day now, tho i truly don't know why....
Earplugs or wearing a headset is another way to exist here in PI. If we could only do a power failure to those noisy places.
