Akustická diagnostika aktivních chráničů sluchu

Abstract

This diploma thesis deals with the topic of acoustic diagnostics of active hearing protectors used in sport shooting. The first part is devoted to the theoretical analysis of this issue. In the theoretical part of the thesis, the basic acoustics concepts related to the topic of the thesis are defined. Furthermore, the effects of noise on human hearing and possible protection against its damage are described, also with selected active hearing protectors. The practical part of the thesis is then oriented to the description of the design of laboratory experimental measurement, its implementation and evaluation of the obtained results. After the laboratory measurements, an experiment with a gas revolver is performed, during which the attenuation of the selected hearing protectors is also determined. In the last part, the hearing protectors are compared with each other and the obtained data are evaluated.
