정량구조물의 차음성능 향상방안 : ″Honeycomb 구조의 적용사례″
Evaluation of the Sound Transmission Loss of a Light Weight Honeycomb Structure
초록
Honeycomb structures have advantages in weight reduction with stiffness increment. As far as noise is concerned, however a light aluminum structure, instead of a steel frame, should have an equivalent mass density in order to maintain sound insulation performance. In this paper, an evaluation of a material effect on noise has been examined.
