The authors aimed to evaluate traffic noise level and noise annoyance in Beijing and the impact of the noise on the quality of life of the residences. The authors performed a cross-sectional study in a 12-floor college dormitory near 4th Ring Road in Beijing, China. The north-side rooms of the building were noisy and had windows facing the road. The authors measured both indoor and outdoor noise. Using both a 5-item verbal scale and a 0-10 numerical scale, they questioned a sample of 1,293 college students living in the dormitory about road-traffic noise annoyance. The results showed that the average outdoor day-to-night noise level was 79.2 dB(A) in the noisy rooms and 64.0 dB(A) in the quiet rooms. Nearly 39% of the respondents living in the noisy rooms indicated that they were highly annoyed by traffic noise according to the response on the verbal scale, and 50% of the respondents living in the noisy rooms were highly annoyed according to the numerical scale.
