Abstract

This bachelor thesis is focused on measurement of the acoustic signals of the mechanical watches and its signal processing for the analysis. Theoretical article introduces to low-level sound measurement issues and represents the most common sensors suitable for the measurement. This article also explains the principles of conversion of analog to digital signal. In this part the principles of sound generation in watch movement are clarified together with the basic defect diagnostics, which can be measured in sound signal. Also, the integrated development environment for the virtual instrumentation with the LabVIEW system description are set forth. The implementation of the practical watchmaker virtual instrument for the diagnostics of the watch movement mechanism is written in the practical section.
