Jet engines are a very unique kind of sound producers. Gaseous or liquid fuel is violently mixed with extremely dense compressed air and then gets burned (don’t do this at home). And this is only one element of the sound. Others are the fan, the compressor, the combustor, the turbine – what the heck – it sounds amazing.
We all know how jet fly bys sound as we’re constantly hearing them above us in passenger airplanes. If you live in a region where fighter aircrafts are practising test flights, you know how low-flying jet engines sound.
BOOM Library recorded F18 Hornet jets from the United States Navy that were flying VERY low above microphones. They deliver those fly by sounds in three distances (close, medium, distant) and three different microphone setups (MS, XY, HH = hammerhead, a custom setup sound designers invented and which is perfect for such recordings). Close and medium have variations containing the typical jet engine whistle.
