Noise represents wasted energy in any engineered system

Evidence

For noise represents escaped energy. The perfect machine would be a silent machine: all energy used efficiently. The human anatomy, therefore, is the best machine we know and it ought to be our model in terms of engineering perfection. — Schafer, Murray R, The Soundscape- Our Sonic Environment…, 677
