れら多孔質吸音材のうち、金属焼結材から成るものは、
金属粉末の粒子間に形成される間隙が立体的に連通して
連通孔が形成され、この連通孔が表面から裏面にまで貫
通しているため、きわめて吸音効果が高い。2. Description of the Related Art In recent years, there has been a strong demand for noise suppression, and sound absorbing plates have been used in various fields. As these sound absorbing materials, porous sound absorbing materials such as metals, ceramics, and synthetic resins have been developed. Of these porous sound absorbing materials, those made of sintered metal materials are
The gap formed between the particles of the metal powder is three-dimensionally connected to form a communication hole, and the communication hole penetrates from the front surface to the back surface, so that the sound absorbing effect is extremely high.
しかしながら、金属焼結材はこのような構造を持ってい
るため、表面は複雑な形状で多数の凹凸があり、使用に
あたっては、表面を塗装し、美観を与えることが望まれ
