you guys aren't alone..i've even gone to the extent of writing in to RSAF to complain about it...and this is what they've replied...
Dear Madam,
Thank you for your email.
The RSAF is mindful of the possible inconvenience to the public as a result of its flying activities over Singapore.
The RSAF has laid down strict rules to reduce noise levels around the airbases, though the noise cannot be totally eliminated. Measures taken include:
i) Lowering the speed of jets when operating over the main island, thus reducing noise emission,
ii) Not conducting night training during school examination periods and ceasing flying activities during school listening comprehension examinations,
iii) Conducting engine ground runs for the fighter aircraft in the Hush House, an enclosure designed to absorb noise during the testing of jet engines.
Most of our training is done over the South China Sea and Pulau Pawai, and at overseas training detachments. To reduce noise and minimise risk, RSAF aircraft avoid the populated areas when they take off for training. RSAF aircraft also fly at higher altitudes in the departure routes.
The relocation of the Flying Training School to Perth, Australia and the introduction of Flight Simulators in the RSAF have significantly cut down aircraft noise.
We also impose similar noise abatement measures on foreign aircraft so as to reduce the impact of flying activities. The measures implemented are meant to create a balance between operational training requirements and consideration for the residents. We are constantly exploring ways to minimise the noise level and hope you can pardon us, in view of the defence for Singapore.
We hope we have been of service to you.
