On July 15, the Ministry of Environment released the results of an airport noise level evaluation that was conducted in 2011. It found that Jeju International Airport’s noise level exceeds the allowable maximum set by the International Civil Aviation Organization (CAO).

In its report, Jeju was found to be 76 WECPNL (short for Weighted Equivalent Continuous Perceived Noise Level). The CAO’s allowable noise level is 75 WECPNL.

WECPNL is a unit of measurement for the degree of noise based on the average noise level, number of aircraft takeoffs and landings, and duration of noise. A rating of 75 WECPNL signifies one can hear the noise from a busy road up to 20 meters away. It is difficult to have a conversation when noise reaches 90 WECPNL.

Gwangju Airport, which is both a civilian and military airport, had the highest noise level in Korea, racking up an 87 WECPNL. Jeju International Airport’s noise level is the highest among civilian airports. Other international airports such as Incheon and Gimpo had a 62 and a 74, respectively.

Four districts near Jeju International Airport also registered more than the CAO’s allowable noise level: Dopyeong-dong (80 WECPNL), Dodu 1-dong (78 WECPNL) Seonghwa Town (78 WECPNL), and Leeho 2-dong (77 WECPNL).

Although Incheon International Airport accounts for 39 percent of Korea’s total international airport landings and takeoffs, it was built relatively far from residential areas. Eight out of 15 Korean airports (Pohang, Jeju, Gimhae, Daegu, Wonju, Cheongju, Gunsan, Gwangju) exceeded the CAO noise level.
