1. Noise
Session 1: Sound generation
Objectives: The impact of noise on the environment is one of the goals in greening air transport of the European Union as mentioned in the Flightpath 2050 vision.
Session 2: Sound propagation and transmission
Objectives: In the neighbourhood of airports sometimes the windowpane starts to clink, especially when the house has windows with single glazing. This can also observed when a helicopter passes the house. In this session the objectives are
Session 3: Sound visualisation
Objectives: Humans can distinguish between the sound of a plane and the sound if a helicopter. Some people can even distinguish different types of planes only by hearing them. In this session the pupils will learn
Session 4: Sound level measurement
Objectives: To protect the public against excessive noise exposure regulations about noise emissions were enacted by the European Union
Session 5: Sound source detection
Objectives: When trying to catch sight of an airplane in the sky we first follow our hearing impression and realize that in many cases the plane can be found at a different place.
Session 6: Noise reduction
Objectives: The used insulation material behind the body shell of a plane is used not only for thermal insulation but also for noise insulation (see fig 10).
Session 7: Measuring the noise level and the noise spectrum of a noise generator (speaker )
Objective1: understanding what is a decibel scale dB, understanding how varies the noise level
for different decibel scales;
Objective 2: understanding what is the white noise; what is a bandwidth
Objective 3: what is the noise level and the noise spectrum, pick values and mediate values
