Abstract: This paper compares a linear interpolation, an interval and a sine interpolation method for measuring mechanical shock duration. All methods are analysed to find differences and limitations. Then methods are tested on simulated and real shock shapes to confirm analysis results. We discovered that the sine interpolation method is very robust to noise, however is sensitive to shock shape changes. The linear interpolation method accuracy is influenced by noise, however this method works also on high noise level (SNR = 0 dB). The interval method provides consistent results up to some noise level (SNR > 10 dB), where it stops working.
