Do aircraft make more noise during take off or when landing?Featured science projectScience project video


 The hypothesis that aircraft will generate more noise during take off rather than during landing is proven to be true. The noise during take off is about 10 to 12 dB louder than the noise generated during landing.

Residents who live near an airport are normally affected by the noise of an aircraft during taking off, noise of aircraft landing and noise of low flying aircrafts. The problems faced by these residents include sleep deprivation, hearing problem, psychological problems and even cardiac disorder. Students and office workers living in these areas may face problems concentrating.

New technologies are being developed by aircraft manufacturers to reduce noise pollution. New standards are also being developed to measure noise from various types of aircraft. Local governments are also creating new laws to limit the noise levels near airports.

Also consider

The experiment can be repeated by taking the measurement at night.

Try to repeat the experiment when it is raining and observe how this affects your results.
