the preset calculation formula in the test module is as follows:
wherein->For the loss value of the hard disk IOPS, k is a positive proportionality coefficient, n is the wave crest number of the actual noise signal exceeding the reference curve on the sensitive frequency band, and +.>Representing the calculated weight corresponding to the most severe reference curve,/->Is the sound pressure level difference at which the noise exceeds the most severe reference curve.
7. A computer device, comprising:
at least one processor; and
a memory storing computer instructions executable on the processor, which when executed by the processor, perform the steps of the method of any one of claims 1-5.
8. A computer readable storage medium storing a computer program, characterized in that the computer program when executed by a processor implements the steps of the method of any one of claims 1-5.
