Description

Noise Absorbing Panel [0002]

The present invention relates to a sound-absorbing panel, and more particularly, to a sound-absorbing panel capable of absorbing sound of various frequency bands.

In recent years, the importance of architectural sound design has been increasing as the level of living has improved and the pleasant cultural life has become increasingly demanded.

Therefore, in public places such as auditoriums, theaters, concert halls, music rooms, etc., there is soundproofing which prevents sound from being transmitted to the outside or external sound from entering. In addition, It can be seen that it has a sound absorbing facility for eliminating the phenomenon.

In addition to the above-mentioned public facilities, it also prevents the noise or vibration generated in the house from being transmitted to the next house, the lower house, and the upper house even in a residential apartment house such as an apartment. On the other hand, And has a sound-proofing facility for blocking inflow.

The sound-absorbing panel, which is widely used as one of such sound-absorbing and sound-absorbing facilities, is installed on a ceiling or a wall surface of a building, so that noise generated in the room is reflected or absorbed to reduce noise.

Korean Utility Model Publication No. 20-2011-0004627 discloses a sound-absorbing panel in which a sound-absorbing material composed of nonwoven fabric or glass fiber is attached to the back surface of a sound-absorbing panel main body having a plurality of perforations formed therein.

Such a sound-absorbing panel does not exhibit a high sound-absorbing performance for each frequency band, but exhibits a sound-absorbing performance limited to a specific frequency. Therefore, it is difficult to expect a sound absorption effect in a space where sound of various frequency bands such as auditorium, theater, concert hall, and music room is generated.

The present invention provides a sound-absorbing panel exhibiting high sound-absorbing properties for sounds of various frequency bands.

The sound-absorbing panel according to the present invention comprises a first sound-absorbing plate on which fine holes are formed; A second sound absorbing plate provided as a melamine foam and positioned on a rear surface of the perforated plate; And a finish material disposed at a predetermined distance from a rear surface of the second sound absorbing plate, and an air layer is provided between the second sound absorbing plate and the finish material.

The total area of the fine holes may be 3 to 30% of the total area of the first sound absorbing plate.

The diameter of the fine holes may be 0.5 to 3 mm.

The thickness of the second sound-absorbing plate may be 25 to 100 mm.

In addition, the air layer may have an area corresponding to the first sound-absorbing plate.

According to the present invention, it is possible to use in a concert hall, opera house, musical theater, multipurpose hall, auditorium, lecture room, church, and cathedral because sound of low frequency band, medium low frequency band and high frequency band is effectively absorbed.

FIG. 1 is a view showing a sound-absorbing panel according to an embodiment of the present invention, FIG. 2 is a plan view showing the sound-absorbing panel of FIG. 1, and FIG. 3 is a sectional view of the sound-

1 to 3, the sound-absorbing panel 1 is provided for eliminating the sound caused by reflection of music or sound in a concert hall, an opera house, a musical theater, a multipurpose hall, an auditorium, a lecture room, a church, do.

The sound-absorbing panel 1 includes a first sound-absorbing panel 10, a second sound-absorbing panel 20, and a finishing material 30.

The first sound-absorbing plate 10 may have a predetermined width and may be made of a material such as wood, plastic, steel plate, or the like. The first sound absorbing plate 10 has a relatively thin thickness. According to the embodiment, the first sound absorbing plate 10 may have a thickness of 0.7 to 3 mm.

In the first sound absorbing plate 10, fine holes 11 are formed. According to the embodiment, the fine holes 11 have a diameter of 0.5 to 3 mm or less. According to the embodiment, the diameter range of the fine holes 11 may be 0.5 to 3 mm.

The fine holes 11 are formed at uniform intervals in the entire area of the first sound absorbing plate 10. The area occupied by the entire fine holes 11 in the first sound absorbing plate 10 is equal to the total area of the first sound absorbing plate 10 Lt; / RTI > According to the embodiment, the area occupied by the entirety of the fine holes 11 in the first sound-absorbing plate 10 may occupy 3 to 30% of the total area of the first sound-absorbing plate 10. Preferably, the area occupied by the entirety of the fine holes 11 in the first sound-absorbing plate 10 occupies 10% of the total area of the first sound-absorbing plate 10. It was experimentally confirmed that the sound absorption performance was drastically decreased when the area ratio of the entire fine holes 11 was more than 30% or less than 3%, and that the sound absorption performance was the best at 10%. The first sound-absorbing plate 10 having the above-described shape exhibited high sound-absorbing property in the middle low frequency band of 100 Hz to 500 Hz.
