FIELD: personal protection equipment.
SUBSTANCE: group of inventions relates to hearing protection devices, which can be used in industrial environments or in environments with high overall noise level. Disclosed is a hearing protection device comprising a controller, a storage device and a receiver. Controller is configured to be connected to a storage device, a receiver and a user notification device configured to notify a user of the hearing protection device. Hearing protection device is configured to receive a data transmission signal from a data transmission device; storing the signal parameter and comparing the data transmission signal with the stored signal parameter. Stored signal parameter is associated with a suitable notification. At that, user notification device is made with possibility, when signal from data transmission device corresponds to signal parameter, output notification to user of device for protection of hearing organs connected to parameter of signal. Data transmission device comprising a processor configured to connect an external signal receiver and a data device transmitter to the receiver. Data transmission device is configured to receive an external signal from an external source and transmit a data transmission signal, configured to be received by a hearing protection device.
EFFECT: use of this group of inventions will make it possible to increase efficiency of information distribution among multiple users of the device for protection of hearing organs.
