Abstract：Objective To explore the detection methodology for audible alarming signals of medical electrical equipment. Methods Two testing platforms were adopted to detect the audible alarming signals of the multi-parameter monitor, including the combination of the noise spectrum analyzer and high bandwidth Tektronix digital oscilloscope as well as the combination of the ear acoustic analysis system and the voice signal analyzer. Results Noobvious differences were seen between the testing results on two platforms under the same environmental conditions. In contrast with the common laboratory, application of the two platforms inthe anechoic chamber could achieve more accurate testing results. Conclusion Detection of the features of audible alarming signals in the anechoic chamber had less interference and could obtain more accurate testing results.
