차음재 번역(영어 번역본)3.1 Method of joining gypsum board: screws and adhesives Figure 2(a) shows single-stud walls; Type 2, which used adhesives to join the boards, had higher sound insulation capacity than Type 2, which used screws, at all frequencies. In the case of the double-stud structures, which generally have better sound insulation capacity, it was shown that Type 4, which was constructed with adhesives, insulated sound better at low frequencies and at 1600Hz, where the coincidence effect may occur. It is believed that adhesives increase the damping effect between the boards, thus improving insulation performance. 3.2 Insertion of an additional board between studs Figure 3 shows the sound insulation capacity of a structure with an additional 12.5mm plaster board inserted inside to enhance insulation performance. In Type 5, the additional board resulted in an increase in the weight of the wall and an actual decrease in insulation capacity, compared to Type 3. It is believed that the inserted board, divides the width of the airspace in the structure and raises the wall’s resonance frequency, thereby negatively affecting the sound insulation capacity at the frequencies evaluated (100Hz – 5000Hz). Therefore, an extra board installed on the exterior would be more effective for enhancing insulation than inserting one inside. 3.3 Installation of insulation material at gaps The reverberation room where the experiments were conducted consisted of two chambers, and the test structures, after having been cased in the test frame, were installed between the two chambers to be measured for their sound insulation performance. A gap occurred between the walls of the reverberation chamber and the test frame installed at the opening between the two chambers; this was blocked by two rubber tubes filled with compressed air. As shown in Figure 4, the gap between the test frame and the walls was filled with absorbent material and finished with acryl, which is reflective. This study examined the effects of the insulation material applied at such gaps. A check was made for resonance, to which such gaps are prone. The results show that in the case of single-stud structures, the lack of insulation at gaps did impair sound insulation slightly between 400Hz and 500Hz, but it had little impact on double-stud structures. 3.4 The curing time of plaster Type C, a single-stud structure with 19mm plaster board, was a model taken from a previous study. Figure 6(b) illustrates the double-stud structure used, the insulation performance of which was affected to some degree by the extent of the plaster’s curing. It is believed that both single- and double-stud structures are affected by the extent of the plaster’s curing. 3.5 Stud types Figure 7 illustrates the sound insulation capacity of structures with wooden and steel studs. Although a direct comparison may be difficult because of the differing width of the wooden and the steel studs used, but it was shown that the structure with wooden studs performed better at medium frequencies. It is believed that wooden studs absorb sound energy better than steel ones. |
