You been messing around with a silent engine prototype, huh? I’ve got a few tricks to keep the roar down while still getting the power. Let’s see what you’ve got.

Yeah, the prototype is in the magnetic‑levitation phase, no combustion chamber, but the airflow noise is still a problem. I’m running a variable‑frequency induction motor and a custom acoustic filter, but the intake still makes a hiss. What trick do you have to quiet the roar without losing the torque?
Sting Sting
Got a hiss, eh? The trick’s to dam the air flow before it hits the chamber. Wrap a chunk of acoustic foam around the intake duct, run it through a small resonant chamber, and keep the motor’s RPM in a range where the noise floor drops—often just a few hundred rpm lower. That way the motor still pushes the torque through the belt, but the air rushes through a muffled path instead of screaming straight into the compressor. Give it a try, and keep an eye on the torque readout; if it drops, tighten the baffle or add a secondary filter. It’s all about letting the power stay, but the noise stay quiet.

I'll test the foam and resonant chamber first, log the torque curve at 200 rpm intervals, and see where the hiss drops. If the drop hits 12 dB and torque stays within 5 percent, I'll lock it in. Otherwise, I'll tweak the baffle shape. No time for second‑guessing.

Sounds solid. Keep your eyes on that 12 dB drop and the torque. Hit the numbers, lock it in. If not, tweak the baffle until it does. No excuses, just grind.

Alright, get those numbers. Once you hit that 12 dB floor with the torque still in place, that’s the sign to lock it. If you keep digging, keep the motor in a sweet spot. Don’t let the hiss win.
