The growling noise is the tips of the fan blades exceeding the speed of sound, around 761 mph, producing shockwaves. Power is reduced at cruise altitude and growling stops as blades slow slightly. In this clip tge pilot increases power for more altitude so transonic growling begins again.
I just always love the sudden moments the pilots put the throttle at full the you can feel yourself going at full speed.
The beautiful sound of tons of air molecules colliding with each other!

@@You2255Tube and one of the things that happens at the speed of sound is what I happened to comment.
Nice video, it's amazing how much they power down after climbing.
Thank you and yes its amazing. One of the reasons the 757 is one of my favorites
PW2037 roar, a little deeper and mellower than the RB211. I assume it's Delta.
sounds like an electric razor in the beginning...
Sounds just like this plane really wants to take off now
🛫💨
1:18 playstation sound
Yea something like that. I hope it wasn’t purposely put in the video.
What is that whoosh sound, anyways?
take two, the h air
That's a pretty long takeoff roll for a 757.
Nope don’t like that sound .. sets my teeth on edge
