Przekazywanie informacji o zagrożeniu pracownikowi wyposażonemu w indywidualny system ostrzegania za pomocą sygnału drganiowego
Transmission of information about danger to an employee equipped with an individual vibrating warning system

Summary/Abstract: The use of hearing protectors is a frequent way to avoid the impact of noise present in the work environment. However, it should be kept in mind that the use of hearing protectors, while reduces the threat created by noise, also diminishes the perception of sounds that are important for the safety of the employee. In such cases, employee’s safety can be improved/increased by using a system to detect the near presence of a moving vehicle. Such a system should be able to transmit information on detected danger to an employee using hearing protectors. The article discusses the possible ways of providing such information to employees using hearing protectors. The advantages and disadvantages of using acoustic, light and vibration signals for this purpose were considered. The authors also present original research results to confront the possibility of perceiving the vibration signal produced by two types of wearables.
