The wedding halls in Korea started to be built as our wedding custom changed under the influence of the Western culture and the Japanese colonial rule in the 1920’s. Most of the wedding halls built in Korea up to recently have been decorated ornately considering the functional and aesthetic elements only, however, sufficient review and plan are for the architectural sound are essential as the performances for the voice and music are simultaneously required within a wedding hall. However, most of the domestic wedding halls which have been built without consideration of the elements for the acoustic performance due to the time and economic reasons are recently causing a lot of problems. In particular, it is the situation that an improvement in the acoustic performance is very urgent for the domestic wedding halls as the adequate sound volume and tone are not secured because of too dry and stiff sound during the officiant’s message, wedding march and nuptial song by using indiscriminate reflection and sound-absorbing materials as well as ornate decorations. From this viewpoint, field measurement tests for six wedding halls of the different shapes and sizes have been carried out in this study to figure out the acoustic defects by measuring the architectural acoustic performance.
Conclusions obtained through this study are as follows.
1. If the NRC of about 0.2~0.5 for each finishing material is considered as some of sound-absorbing material, most of the finishing materials in the six target wedding halls are composed of the reflective materials, which are judged to affect the acoustic performance of the wedding halls. Therefore, it is regarded that the choice of sound-absorbing materials is most important to ensure the optimal acoustic performance in the existing wedding halls.
2. When various sound evaluation indexes of the wedding halls through field tests were identified, the SPL averaged 70.8~73.0dB (A). When we looked at the average of each sound evaluation index at 500Hz, the evaluation criteria of acoustic performance, SPL(dB) exhibited 61.6~68.3dB, RT 1.11~1.34 seconds, EDT 1.03~1.27 seconds, D50 36~50.6%, C80 0.78~2.94dB and RASTI 61~67% respectively. Accordingly, the sound pressure levels in wedding halls are relatively uniform, but it is considered to be difficult to obtain the clear and rich tone as other sound evaluation indexes do not satisfy the acoustic characteristics of a wedding hall.
3. As a result of comparison of the actually measured reverberation time and the optimal reverberation time suggested by Kundsen-Harris, The duration of 0.18 seconds for Dream Hall, 0.08 seconds for Lily Hall, 0.15 seconds for Vista Hall, 0.25 seconds for magic Hall, 0.15 seconds for Convention Hall and 0.17 seconds for Happy Hall was respectively exhibited. Therefore, in order to satisfy the optimal reverberation conditions in a wedding hall, a proper selection of finishing materials is required; the area and arrangement should be decided by considering the architectural acoustic characteristics.
