Abstract
Description
本發明係關於一種材料性質的檢測裝置及方法,尤其是一種用以檢測抗噪音材料的抑音效果的能量吸收材料的檢測裝置及方法。 The invention relates to a material property detection device and method, in particular to an energy absorption material detection device and method for detecting the sound suppression effect of anti-noise materials.
習知抗噪音材料的抑音效果檢測方法,大多依照產生噪音的物件或環境而有所不同。例如,當噪音來自一特定的發聲體(如:馬達、風扇或風機等)時,係將一待測材料塗附於一板件,該發聲體所發出的噪音聲波將傳遞至塗附有該待測材料之板件,該待測材料反射一聲壓,以由一收音器所接收之聲壓評斷該待測材料的抑音效果。惟,該檢測設備需包含該發聲體,導致檢測設備成本提升;且該檢測結果僅針對特定的發聲體,當發聲體變更時,該檢測結果即無法適用。 Conventional methods for detecting the sound suppression effect of anti-noise materials differ according to the object or environment that generates noise. For example, when the noise comes from a specific sound-generating body (such as a motor, fan, or fan, etc.), a material to be tested is applied to a board, and the sound waves emitted by the sound-generating body will be transmitted to the sound-coated body. The board of the material to be tested reflects a sound pressure, and the sound suppression effect of the material to be tested is judged by the sound pressure received by a microphone. However, the detection device needs to include the sounding body, which leads to an increase in the cost of the detection equipment; and the detection result is only for a specific sounding body. When the sounding body changes, the detection result cannot be applied.
另,當噪音來自多個的發聲體時,則需要營造一較複雜之發聲與接收系統,以致檢測設備與環境建構不易,造成檢測成本之提升。特別是,對於一個原本就存在有複合式噪音的環境(如:船艙、機房或工場等)而言,檢測的方法則是需要直接將待測材料塗附於該環境四周的牆面,並直接在該環境中收音;因此,需要比較不同抗噪音材料的抑音效果時,光是每次選用一種待測材料塗附於該環境四周的牆面就是一大工程,使得檢測工作十分耗時且高成本。 In addition, when the noise comes from multiple sounding bodies, a more complicated sounding and receiving system needs to be built, so that the construction of the detection equipment and environment is not easy, resulting in an increase in the cost of detection. In particular, for an environment where compound noise originally exists (such as: cabin, engine room, workshop, etc.), the detection method is to directly apply the material to be tested to the wall around the environment and directly Radio in this environment; therefore, when it is necessary to compare the sound suppression effects of different anti-noise materials, it is a major project to select a material to be tested and apply it to the wall around the environment each time, making the detection work very time-consuming and High cost.
有鑑於此,習知抗噪音材料的抑音效果檢測裝置及方法,確實仍有加以改善之必要。 In view of this, it is indeed necessary to improve the conventional sound suppression effect detection devices and methods of anti-noise materials.
