Description

The utility model relates to the field of means of providing orientation, obtaining information by persons with various diseases of the sensory organs, in particular, devices for facilitating the receipt and perception of sound information.

Sound information devices are widely known, designed to acoustically inform an unlimited circle of people of various kinds of information, for example, about the location, purpose of infrastructure objects, and the sequence diagram.

The proposed wall-mounted information system for the hearing-impaired is designed to transmit audio information to people with impaired hearing function, using hearing aids in the induction coil “T” mode, at an increased level of ambient noise or in the presence of obstacles between interlocutors, in public places, in public service areas (near racks information, box office).

For example, a talking information plate [1] is known for storing and reproducing audio information of various nature, for example, information about the purpose of the room, work schedule, etc. The device consists of a housing, a power source, a control unit connected to a memory unit, a microphone, microphone activation button, play button, electro-acoustic transducer.

The operation of the device is as follows. The necessary information recorded by means of a microphone is stored in a memory unit. When you click on the play button, information through the control unit is extracted from the memory unit, converted into an analog signal and voiced by an electro-acoustic transducer.

The disadvantage of this device is the limited transmission efficiency of audio information. So, the device is not able to transmit acoustic information to people suffering from a hearing disease, causing it to partially lose or weaken. The device does not contain elements that allow for the delivery of sound information to persons with hearing impairment. Since the device is located in a public place where the level of external noise does not allow people with hearing impairment to perceive sound information reproduced by the device, and an increase in the volume level of the device’s speaker is not structurally provided and may be unacceptable due to restrictions on the volume level in public places. The device is also deprived of the technical ability to connect to special equipment to ensure the delivery of sound information by other methods than playback through a sound emitter, for example with an amplifier of induction systems, for the hearing impaired.

A sound information device [2] is known, selected as a prototype, consisting of a housing, a power source, a control unit connected to a memory unit, a play button and an electro-acoustic transducer, characterized in that a pairing unit is included in the circuit between the control unit and the electro-acoustic transducer, output which is connected to an electrical connector for connecting special equipment.

The utility model is implemented as follows. When a hearing-impaired user presses a play button, the information previously recorded in the memory unit is transferred through the control unit to the circuit between the control unit and the electro-acoustic transducer in the form of a signal. Through the interface unit, the signal is fed to an electrical connector for connecting special equipment. The signal coming through the electrical connector for connecting special equipment is processed by the connected special equipment, for example, an induction loop amplifier. After processing the signal through the induction loop, it enters the user's hearing aid and is individually voiced, without interference and with a given volume and quality.

The disadvantage of this device is the lack of effectiveness in the transmission of sound information to people suffering from a disease of the hearing organs, causing its partial loss or weakening. This is extremely important when the system is located in a public place where the level of external noise does not allow persons with impaired hearing guaranteed to perceive sound information reproduced by the device.
