摘　　要：基于现有的有源消噪耳罩的测试参量和测试方法,提出了有源消噪耳塞的测试方法,建立了测试系统并分析了测试系统误差和测试可靠性。详细给出了基于此测试系统的测试方法,并对3款耳塞进行了测试,通过分析结果,验证所提出测试方法的可行性。Based on the existing measurement parameters and methods for the circumaural headsets, an acc-urate methodology for active noise control earplug measurement is proposed. A test system with proper equipments is established and its possible error and reliability are analyzed. The measurement method is described in details, and three commercial active noise control earplugs are tested. The measurement results verify the feasibility of the proposed methodology.
