Abstract
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.
