    • The invention relates to a dynamic hearing protection device to be worn completely in a user's ear canal (10), comprising: a lateral part (32, 36) and a medial part (34, 36) flexibly connected in such a manner that the lateral part and the medial part can bend relative to each other so as to follow the shape of the ear canal, wherein the medial part is to be inserted at least in part into the bony part (16) of the ear canal and comprises an acoustic damping element (70) at its periphery which is adapted to touch the wall (18) of the bony part of the ear canal for attenuating sound impinging on the hearing protection device, wherein the lateral part includes a microphone arrangement (42) including a microphone port (41) for capturing audio signals from ambient sound, wherein the microphone port is to be located at least 1 mm inside the ear canal, wherein the hearing protection device includes a non-replaceable battery (48) and an audio signal processing unit (44) for processing the audio signals captured by the microphone assembly, wherein the medial part includes a loudspeaker (52) for stimulating the user's hearing according to the processed audio signals, and wherein the audio signal processing unit is adapted to provide at least for an attenuation mode in which the gain applied to the audio signals is less than the mechanical acoustic damping provided by the hearing protection device when worn in the ear canal.
    • 本发明涉及一种完全佩戴在使用者的耳道(10)中的动态听力保护装置,包括:外侧部分(32,36)和内侧部分(34,36),其柔性地 以这样的方式连接,使得外侧部分和内侧部分可以相对于彼此弯曲以跟随耳道的形状,其中内侧部分将至少部分地插入到耳道的骨部分(16)中, 耳道并且在其周边处包括声阻尼元件(70),所述声阻尼元件适于接触耳道的骨部分的壁(18)以衰减撞击在听力保护装置上的声音,其中所述侧部包括麦克风 包括用于捕捉来自环境声音的音频信号的麦克风端口(41)的布置(42),其中所述麦克风端口应位于所述耳道内至少1mm处,其中所述听力保护装置包括不可更换电池(48) 和音频信号处理单元(44),用于进行处理 对由所述麦克风组件捕获的音频信号进行取样,其中所述中间部分包括用于根据所述处理后的音频信号来刺激用户的听力的扬声器(52),并且其中所述音频信号处理单元适于提供至少衰减模式 其中施加到音频信号的增益小于戴在耳道中时由听力保护装置提供的机械声学阻尼。
