Hey guys, does anyone know what is the maximum noise level (dBA) of aircon allowed in HDB units? Neighbour complained my aircon is loud, but I said no. So I bought a SPL meter to check, but HDB don't have any guidelines on the max noise level permitted for aircon unit. They just sent people come, listen with their golden ear & pass verdict, which I defer to be unprofessional & unaccaptable. NEA has a table for permitted noise level but it's for construction work, nothing for aircon. Noise Pollution So, what can I do? With no guideline on residential aircon noise level, who's argument is right or wrong? Or HDB officer is king, what they say is must be right? Any advice?
