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

Materials

The materials required for the experiment:

  • A decibel meter for measuring noise
  • Ear plugs
  • A safe location near an airport to view aircraft take off and landing
  • Approval from the relevant airport authority (if necessary) to conduct the experiment near the airport

Procedure

  1. For this experiment, the independent variable is the type of aircraft and the stage at which the noise is measured (take off and landing). The dependent variable is the noise level. This is determined by measuring the noise level with a decibel meter. The constants (control variables) are the distance from the aircraft, the length of the runway, and the type of decibel meter used to measure the noise levels.
  2. The flight schedules for different types of aircraft types which are landing and taking off from the selected airport is obtained. Depending on your location, you might be able to obtain this information online from the airport authority website or you might have to speak to the relevant customer relations team. Three readings are taken during take off and landing for the following types of aircraft ?Boeing 747, Airbus 300 and Cessna 206.
  3. The area surrounding the airport is surveyed to find a safe location to set-up the measuring equipment and be able to visually observe the types of aircraft taking off and landing.
  4. As the aircrafts take off and land according to the schedule printed out, the measurements are taken and recorded in the table given below.

Project cost ($):
50
Time required:
1 hour to prepare, 2 day for experiment
Material availability:
Easily found. You can obtain a decibel meter from Radioshack at around US$50
Safety concerns:

The area around the airport will have tight security checks and safety requirements. Please ensure that you obtain proper clearance from airport authorities if the selected location is too close to the airport. Please wear proper ear protection
