In aerospace and automotive industries...
Do you think living high up will keep you away from noise? The truth may be quite the opposite!
2025-11-04
Traffic noise is a "high-altitude attack." Ground noise from cars, subways, and other sources travels upwards as refracted waves. Lower floors are shielded by buildings and trees, creating a "sound shadow zone," while higher floors are directly exposed to the sound wave radiation. At night, when it's quiet, the sound of traffic from a highway 2 kilometers away can be clearly heard on the 30th...
