Zusammenfassung:Systems and methods for checking the relative sensitivity of two or more microphones of a hearing protection device include sensing ambient sound using two or more microphones of the hearing protection device and sampling the ambient sound. A sample of the ambient sound may be used to determine whether the ambient sound is sufficient to determine microphone sensitivity, and to determine whether a threshold relative sensitivity of the two or more microphones is reached. A pass indication or a failure indication may be provided to the user based on whether the threshold relative sensitivity is reached. 用于检查听力保护设备的两个或更多个麦克风的相对灵敏度的系统和方法包括使用该听力保护设备的两个或更多个麦克风来感测环境声音并且对该环境声音进行采样。该环境声音的样本可用于确定该环境声音是否足以确定麦克风灵敏度,并确定是否达到该两个或更多个麦克风的阈值相对灵敏度。可以基于是否达到该阈值相对灵敏度来向用户提供通过指示或失败指示。
