The search for relations between the energy of vibration penetrating the hands of an operator of hand vibration tool and the energy generated in this tool reąuires an appropriate vibration transfer function. The signals measured in this problem are non-stationary, this may be caused by considerable changes of the pressing force and the force of grip during the working process. In the paper the new concept of calculating the appropriate transfer function is presented. It consists in the use of the wavelet transform instead of the classical definition of the Fourier Transform, since the assumptions for the latter are hardly met in the application considered here. The attempt to use the wavelet transform in the process od identi-fication of the transmission of vibration into operator's hands resulted from the analysis of the properties of the kernel of this transform, which makeę it appropriate for the analysis of transfer functions in systems operating in non-stationary measuring conditions. The theoretical cosiderations have been completed by computer simulations and experimental research of vibration transmitted onto operators of impact tools. They can be used as a contribution in the search for a synthetic indicator characterising the conditions for minimisation of these processes.

Przedstawiono prototypowy system monitorowania hałasu skonstruowany w Katedrze Systemów Multimedialnych Politechniki Gdańskiej. W szczególności zaprezentowano rozwiązania przenośnego systemu pomiarowego, wykorzystującego interfejs pomiarowy przyłączany do komputera za pośredctwem portu USB oraz oprogramowanie lokalne i oprogramowanie serwera, pozwalające na tworzenie map akustycznych. Ponadto zaprezentowano w skrócie wdrożony system przesiewowych badań słuchu i szumów usznych. Obie wymienione aplikacje zawierają bazy danych, których zawartość pozwala na poszukiwanie korelacji pomiędzy występowaniem hałasu i upośledzeń słuchu na obszrach zamieszkiwanych przez duże liczebnie populacje.
