Noise pollution is unwanted sounds affecting human health and environment. Humans can hear sounds from 20 to 20000 Hertz. Sound intensity measured in decibels (dB), normal hearing range is 0-140 dB
Munich Airport (EDDM/MUC) located at 14380° 21.2' E011° 47.2'. Airport has three concrete runways: 08L, 08R, and 26L/26R. Night flights restricted from 2200-0600LT for noise abatement
PAGA system broadcasts emergency messages and alarms throughout facilities. System design depends on facility layout and required components. Components must meet safety standards like ATEX/IECEx for offshore platforms. Sound coverage study recommended for optimal speaker placement
X-ray generation and detection are random processes governed by natural laws. Statistical noise affects image quality at different exposure levels. Radiologists accept some noise for easy-to-diagnose injuries
Ambient noise from phones and machines affects productivity significantly. Optimal workplace temperature is 70-75°F for maximum productivity. Poor office design can reduce comfort and productivity
Noise figure indicates signal-to-noise ratio degradation in signal chains. Noise factor is ratio of output noise to thermal noise at standard temperature. Noise figure is logarithm of noise factor, expressed in decibels
