    you’re very wrong btw.

    This is a well known fact about how sound travels through the environment. Lower pitch noises (gas engines) tend to travel very far and very aggressively. They’re so much more potent.

    High pitched whining sounds (electric motors) don’t travel nearly as well as lower pitch sounds, and they tend to be much much quieter at distance.

    Combine that with the sound profiles of the ICEs compared to the constant whine of an electric motor in a certain part of the spectrum of audible sound. Now you have modulation on the ICE which is going to be much more potent to begin with, since it’s an entirely different sound profile. As well as being much harder to tune out, given the fact that it’s not just a persistent whine.

    This is why the abrams powered by a gas turbine are known for being incredibly quiet, even though when up close, you can still hear them loud as shit. The sound just can’t travel through the environment as effectively, and like i said, even if it does. It’s not exactly the incredibly distinct sound of an ICE.

      I addressed that in another comment, at the point source the DB is the same, but the percussive sound of the engine travels further.

        yeah, and that’s a good thing?

        I mean sure you might have to wear hearing pro still. But that’s not my problem, what is my problem is having unavoidable hearing damage from my neighbors who are currently mowing.
