Description
【０００１】[0001]
本考案は、吸音パネルに関するものである。 The present invention relates to a sound absorbing panel.
【０００２】[0002]
従来の吸音パネルとしては、石膏ボード（厚さ12mm）とグラスウールとからな るベースの表面に、化粧用ガラスクロスを貼着したもの、あるいはベニア板（厚 さ９mm）とグラスウールとからなるベースの表面に、化粧用ガラスクロスを貼着 したものが知られている。 As a conventional sound absorbing panel, a base made of gypsum board (thickness: 12 mm) and glass wool, with a decorative glass cloth attached to the surface, or a base made of veneer board (thickness: 9 mm) and glass wool. It is known that the surface is adhered with a glass cloth for makeup.
【０００３】[0003]
前記従来の各吸音パネルにあっては、足音、反響音等、 500Hz以下の低音域の 吸音率は比較的良好であるが、会話等、 500〜2000Hzの中高音域の吸音率に劣る 問題がある。 Each of the conventional sound absorbing panels described above has a relatively good sound absorption coefficient in the low sound range of 500 Hz or less such as footsteps and reverberation sounds, but has a problem of poor sound absorption coefficient in the middle and high sound range of 500 to 2000 Hz such as conversation. is there.
【０００４】[0004]
本考案は、前記従来の吸音パネルの問題を解決すべくなしたものであって、そ の要旨とするところは、繊維系吸音材料からなるベースの表面に、ステンレス箔 を貼着した吸音パネルにある。 The present invention has been made to solve the problems of the conventional sound absorbing panel, and its gist is to provide a sound absorbing panel in which stainless steel foil is adhered to the surface of a base made of a fiber sound absorbing material. is there.
【０００５】[0005]
厚さ12mmの石膏ボードと、密度96kg／m3、厚さ25mm（ＪＩＳ仕様）のグラスウ ールとからなるベースの表面に、化粧用ガラスクロスを貼着した従来の吸音パネ ル（図１、図２のグラフＡ）および厚さ９mmのベニア板と、前記と同仕様のグラ スウールとからなるベースの表面に、化粧用ガラスクロスを貼着した従来の吸音 パネル（図１、図２のグラフＢ）と、前記と同仕様のグラスウールからなるベー スの表面に、厚さ 0.2mm以下のステンレス箔（平板）を貼着した本考案に係る吸 音パネル（図１、図２のグラフＣ）および前記と同仕様のグラスウールからなる ベースの表面に、厚さ 0.2mm以下のステンレス箔（エンボス加工、ヘアーライン 加工等を施した模様入り）を貼着した本考案に係る吸音パネル（図１、図２のグ ラフＤ）とを、背面空気層を０mm（図１のグラフ）と 100mm（図２のグラフ）の 二条件においてそれぞれ垂直入射吸音率測定法により２回測定したところ、 500 Hz以下の低音域の吸音率（２回測定の平均値）は、各吸音パネルともそれ程の差 異はなかったが、 500〜2000Hzの中高音域の吸音率（２回測定平均値）では、本 考案に係る吸音パネルの方が優れている。このことは、ステンレス箔が、 600〜 800Hzの音域で振動する特性を有しており、その振動音をグラスウール層にお
い て効率よく吸収できることから、結果として、 500〜2000Hzの中高音域の吸音率 が、従来の吸音パネルよりも優れているのである。A conventional sound-absorbing panel in which a decorative glass cloth is attached to the surface of a base consisting of a 12 mm-thick gypsum board and a glass wall having a density of 96 kg / m 3 and a thickness of 25 mm (JIS specification) (Fig. 1, A conventional sound-absorbing panel in which a decorative glass cloth is adhered to the surface of a base made of a graph A in Fig. 2) and a 9 mm thick veneer plate and glass wool having the same specifications as the above (graphs in Figs. 1 and 2). B) and a sound absorbing panel according to the present invention in which a stainless foil (flat plate) having a thickness of 0.2 mm or less is attached to the surface of a base made of glass wool having the same specifications as above (graph C of FIGS. 1 and 2). And a sound absorbing panel according to the present invention in which stainless steel foil (with a pattern with embossing, hairline processing, etc.) with a thickness of 0.2 mm or less is attached to the surface of a base made of glass wool of the same specifications as above (Fig. 1, Fig. 1). 2 Graff D) and the rear air Was measured twice under the two conditions of 0 mm (graph in Fig. 1) and 100 mm (graph in Fig. 2) by the normal incidence sound absorption coefficient measurement method. The sound absorption coefficient in the low frequency range of 500 Hz or less (average value of two measurements) ) Is not so different from each sound absorbing panel, but the sound absorbing panel according to the present invention is superior in the sound absorbing coefficient (average value of two times measurement) in the mid-high range of 500 to 2000 Hz. This is because the stainless steel foil has the characteristic of vibrating in the frequency range of 600 to 800 Hz, and the vibrating sound can be efficiently absorbed in the glass wool layer.As a result, the sound absorption coefficient in the mid to high range of 500 to 2000 Hz is achieved. However, it is superior to the conventional sound absorbing panel.
