It is all about noise. Health impacts are mainly focusing on the night-time (sleep disturbance), Visual aspect is not recognised as annoying as such. <\/p>\n\n\n\n
Noise is a combination of aircraft type and engine configuration (same types of aircraft can be equipped with different engines). <\/p>\n\n\n\n
Noise is a wave, so no displacement of air, just a pressure wave. <\/p>\n\n\n\n
Ornaments and vibrating windows are related to the interactions between the sound wave and the object it falls on. <\/p>\n\n\n\n
If the frequency of the sound matches the natural frequency of the object, then it starts to vibrate. <\/p>\n\n\n\n
You can compare it with pushing a swing, if you push in the matching frequency, the swing will gain amplitude, that’s the vibrating window.<\/p>\n\n\n\n
Vibrating things start to emit sound by themselves and is called ‘secondary sound’.<\/p>\n","protected":false},"excerpt":{"rendered":"
