Jet engine audio glitches periodically due to reference frame recenter

Ok so I was using the Wasp 2.0 moving around a little , then I noticed that the engine makes some weird noises (like the normal noise it makes but amplified and it only last less than half a sec) every 5 or so seconds . I don't know if it's the altitude , the "type" of engine or it's just my PC outlet that bugs (I don't think so but still) but even thought it's not that bothering , fixing it would be nice !(for info , I am standing at 12 000 meters above sea level and have a surface speed of 584m/s)
