Sound Sound analysis
sound A-3-7 Tracking analysis of sound and vibration from the rotation machine
 

 

  • The sound level generated from rotationg machine is changed with respect to the number of rotations.
  • In this example, AC output from LA-7500 precision sound level meter, which can measure the sound level in wide range of frequency maximum at 25 kHz, is used instead of microphone. Input the AC output into the DS-3000 series in order to display the changing of sound level due to the rotational change. It displays the number of rotations on the X axis and the sound level component according to the number of rotations on the Y axis (tracking analysis).
  • It requires consideration that the measurement result may not be affected by the reflected sound from floor surface.
