Picture of a noise monitoring station

Noise levels vary between aircraft and depend on various factors such as aircraft type, size, weight, altitude, and weather conditions to name a few. 

In 1972, the International Civil Aviation Organization (ICAO) established the first noise emissions standards for aircraft.  Since then, aircraft designs have evolved significantly to reduce noise emissions at its source.  With every new iteration of the noise emissions standard, aircraft must adopt the latest available noise reduction technology. 

At YYC, our passenger airline partners have been updating their fleet with new state-of-the-art aircraft that are more fuel efficient and produce less noise.  It is anticipated that older aircraft will be retired and replaced with newer aircraft, which over time, will result in a quieter fleet.

ICAO's Standards

Any aircraft certified after December 2017 must meet Chapter 14 noise emissions standards. Click here to learn more.
