A hearing protector device (9) comprising a controller (11), a memory (14), and a receiver (12) is provided. The controller (11) is configured to be connected to the memory (14), the receiver (12) and an at least one user-notifying device (31) adapted to notify a hearing protector user. The hearing protector device (9) is configured to receive at least one data transmission signal from a data transmission device (20)； storing at least one signal parameter； and comparing said data transmission signal to the at least one stored signal parameter. The at least one stored signal parameter is associated with at least one suitable notification； wherein the user-notifying device (31) is configured to, when the signal from the data transmission device (20) matches the signal parameter, present the at least one notification associated to the signal parameter to the hearing protector user. A data transmission device (20) comprising a processor (21) configured to be connected to an external signal receiver (22) and a data device transmitter (23) is also provided, wherein the data transmission device (20) is configured to receive at least one external signal from an external source (40) and transmit a data transmission signal configured to be received by at least one hearing protector device (9).La présente invention a trait à un dispositif de protection auditive (9) comprenant un dispositif de commande (11), une mémoire (14), et un récepteur (12). Le dispositif de commande (11) est configuré pour être connecté à la mémoire (14), au récepteur (12) et à au moins un dispositif d'alerte de l'utilisateur (31) conçu pour alerter un utilisateur du dispositif de protection auditive. Le dispositif de protection auditive (9) est configuré pour recevoir au moins un signal de transmission de données provenant d'un dispositif de transmission de données (20) ； le stockage d'au moins un paramètre de signal ； et la comparaison dudit signal de transmission de données audit paramètre de signal s
