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

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

Objectives: To protect the public against excessive noise exposure regulations about noise emissions were enacted by the European Union

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.

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).

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
