Semi-silencing anechoic chamber
The semi-silencing anechoic chamber comprises a bottom surface, a top surface and a plurality of side surfaces, the side surfaces are arranged on the bottom surface in a surrounding manner, the top surface is connected with the side surfaces, and the bottom surface, the top surface and the side surfaces are matched to form the anechoic chamber. According to the semi-silencing anechoic chamber, the sound insulation layer, the shielding layer, the first wave absorbing layer, the second wave absorbing layer and the sound absorbing layer are sequentially arranged on the top face and the side face from outside to inside, sound waves outside the anechoic chamber are isolated through the sound insulation layer, and received electromagnetic waves are guided into the ground through grounding of the shielding layer; the first wave-absorbing layer and the second wave-absorbing layer cooperate to absorb internal electromagnetic waves with different frequencies, and the sound-absorbing layer absorbs internal sound waves. The semi-silencing anechoic chamber can meet acoustic indexes and electromagnetic shielding performance at the same time, and can provide an electromagnetic test environment meeting the EMC test of an artificial cochlea implantation system and a hearing aid.
本发明公开了一种半消声电波暗室，其包括底面、顶面和多个侧面，多个侧面围设在底面上，顶面与多个侧面连接，底面、顶面和侧面配合形成暗室。本发明的半消声电波暗室通过在顶面和侧面由外向内依次设置隔音层、屏蔽层、第一吸波层、第二吸波层、吸音层，通过隔音层隔绝暗室外部的声波，通过屏蔽层接地将接收的电磁波导入大地，通过第一吸波层和第二吸波层配合吸收内部不同频率的电磁波，通过吸音层吸收内部的声波。本发明的半消声电波暗室可以同时满足声学指标和电磁屏蔽性能，可以提供满足人工耳蜗植入系统及助听器EMC测试的电磁测试环境。
