The present invention relates to a method of detecting and processing acoustic signals emitted from reciprocating, oscillating or rotating objects for the purpose of recording and predicting changes in the condition of the objects. The invention also relates to an apparatus adapted to carry out the method. In particular, the method is useful in the on-line or off-line prediction of conditions and performance of internal components in machinery, so as to allow for so-called condition based maintenance, for example. |
