Hush kit for the Pratt and Whitney JT8D-1 through -17 engines
A hush kit is an aerodynamic device used to help reduce the noise produced by older aircraft jet engines. These devices are typically installed on older turbojet and low-bypass turbofan engines, as they are much louder than later high-bypass turbofan engines.[1]
Hush kits are used because the engines on jet aircraft generate a large amount of noise, which significantly increases noise pollution near airports.[2]
