Countering Traffic Sounds (04-12-24)
Deng, Rising, Gu, and Bimal evaluated the effects of various soundscapes on the stress generated by traffic noise. They report that “mixing baseline traffic noise with water sound at a low SNR [signal-to-noise ratio] significantly reduced stress, whereas mixing with the white noise of a high FC [fractal complexity] increased stress. This discovery highlights the varying stress-mitigating effects of distinct fractal sounds on traffic noise and advocates for the application of water sound with a low SNR and low FC as an effective criterion for urban noise mitigation strategies. . . .
