Abstract

本发明公开了一种自适应ANC耳机测试方法、装置及存储介质，本发明通过响应于音频分析仪的指令进入静态ANC模式，通过所述ANC模式增益接收所述音频分析仪在所述第一范围内的音频信号，音频分析仪中的自适应增益的第一范围与自适应ANC耳机的寄存器存储的ANC模式增益的第二范围相同，根据所述音频分析仪发送信号至噪声音响所产生的噪声信号进行反馈增益校准，当所述反馈增益校准通过，进行混合ANC增益校准，否则确定测试结果为不良品，当所述混合ANC增益校准通过，确定测试结果为良品，否则确定测试结果为不良品，在自适应ANC耳机中新增静态ANC模式，可以在不影响自适应ANC耳机原有的自适应降噪功能的情况下进行有效的测试。
