Problems solved by technology

However, since these materials are very harmful to the human body, it is difficult to use these materials properly
[0011] [11] Therefore, since the sound-absorbing holes 31 are limited in the sound-absorbing panel composed of resin foam and non-woven fabric for high sound levels, it is difficult to uniformly absorb sound waves belonging to a wide frequency band range

Abstract

The present invention relates to a sound-absorbing panel in which the structure of a vibration type sound-absorbing panel for absorbing and offsetting sound waves belonging to a low frequency band is modified to improve a sound absorption effect. A sound-absorbing panel comprises a panel body opened on a lower end thereof and formed on the lower end thereof with a rib which extends outward by a predetermined length, and a plurality of sound-absorbing holes defined on an upper surface of the panel body and possessing a sectional shape of a predetermined figure, each sound-absorbing hole being tapered downward to have an inside space which has a gradually decreasing size and then linearly perforated to have an inside space which has a constant size.

Description

technical field [0001] [01] In general, the present invention relates to a sound-absorbing panel, and more particularly, to a sound-absorbing panel whose structure is modified by vibrating and absorbing holes formed on its surface to reflect, absorb, Offsets and blanks sounds, improving sound absorption. Background technique [0002] [02] As known to those skilled in the art, sound absorption means the fact that, when a sound wave reaches a material surface, the sound wave is converted into vibration energy or thermal energy of the material by reflection or the like. [0003] [03] In the past, sound absorption technology was only used in performances, theaters, studios, etc. However, sound absorption technology has been applied in various industrial fields and various noble living standards nowadays. In addition, even attention to home sound absorbing materials is increasing. [0004] [04] In this field, there are already disclosed sound-absorbing panels that use porous m...
