Research on the Performance, Measurement, and Influencing Factors of the Acoustic Environment in Hospital Buildings

Abstract

In this study, the current noise situation in eight hospitals in central and northern Taiwan was investigated and analyzed. Recording equipment was utilized to measure environmental noise levels at the busiest points in the hospital lobby, specifically the pricing and medicine waiting areas. Furthermore, the acoustic data of the recorded audio samples were analyzed to determine the psychoacoustic parameter, namely, loudness. Subsequently, correlation analysis was performed between the analyzed data spectrum and the subjective psychological noise value. Ultimately, it was found that the mid-frequency band (MF) had a greater impact on the subjects compared to the other two frequency bands. When comparing the correlation coefficient analysis with the prior factor analysis, the primary sources of intrusive noise affecting the subjects were identified. The mid-frequency band is predominantly attributed to footsteps and conversations, and the high-frequency band is predominantly attributed to broadcast sound.
