No, that's a complete non sequitur. Efficiency and noise production are not directly related, and can frequently be anti-correlated.
Just to take an example, the single-speed helical gearboxes used e.g. by Tesla are a prime example of sacrificing efficiency in an EV just to reduce noise.
Using a straight-cut transmission like they do e.g. in Formula E would be more efficient, more lightweight at the same torque rating, and a lot more noisy.
