This paper proposes an optimization scheme for residential acoustic environments based on the Iling formula and standing wave theory. A music-based low-frequency electromagnetic vibration physiological feedback therapy system was designed to achieve synergistic effects between music therapy and physiological parameter monitoring. Forty healthy adults aged 20–35 were selected as experimental subjects, and six different feature selection methods were applied to determine useful features. Key acoustic environment indicators were obtained through analysis of the acoustic parameters of residential spaces. Combining electroencephalogram (EEG) power spectrum and EEG coherence analysis results, the effectiveness of integrating music therapy into residential environments was validated. Analysis of residential space acoustic parameters revealed no significant differences in sound signal reception time between central and lateral sound source positions. The sound signal reception time difference between the front and rear measurement points was 25.91 ms, with significant differences in early reflection sound reception changes between 0–50 ms at the front and rear measurement points. After music therapy, the participants showed a significant increase in coherence in the alpha band occipital region, while other regions showed a slight downward trend. The changes in beta band coherence were more significant, with an increase of 0.152 (p<0.01) in frontal region coherence and a decrease of 0.081 (p<0.05) in temporal region coherence. This demonstrates that music therapy conducted in a residential environment can serve as an effective method for regulating negative emotions and cognitive attention, while EEG signal characteristics can serve as an effective assessment tool.
