Jinci temple is an important historical and cultural heritage in China, and is also a religious sacrificial place in Taiyuan city. It is composed of two parts, the external park and the internal museum. The sound environment in it is still unknown currently. In this paper, the most representative locations on the main tourist routes in these two parts were selected, sound elements were explored, and A sound level measurement and preliminary quantitative research were carried out. It was found that sound pressure level is negatively correlated with frequency at almost all positions in Jinci museum. Subsequently, by taking into account the close correlation between acoustic environment and people's psychological feelings, the most important evaluation factor of acoustic annoyance was selected, and the weighted loudness values of A(annoyance factor) and L(frequency factor) were derived from the LAeq value. Finally, the weighted loudness values were compared with the sound pressure level value. It was concluded that the LAL value after adding the weight of annoyance(A) is smaller than the L value without A weighting, and the higher the low-frequency SPL values below 1 kHz, the smaller the loudness values. In the high frequency range, the sensitivity of SPL on weighted loudness remains unchanged.
