Abstract：Objective To evaluate the variation of software warning signal on different medical devices. Methods The warning signal
of the same acoustic profile generated by different mobile medical device was detected by a noise spectral analyzer in combination
with broadband digital oscilloscope. Results The frequency features of the warning signal variated among different medical devices,
and discrepancies happened according to the industry standards. Conclusion Medical devices, which used mobile platforms to
generate warning signals, should propose more strict requirement on software and hardware configuration, and put more emphasis on
the warning function during regulation.
