Deletion of Impact spectrometer

Comment: There is a type of diagnostic procedure in materials science called Acoustic emission analysis and some types of acoustic emission testing involve impact events to generate the acoustic emissions, e.g., http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.30.3195&rep=rep1&type=pdf this paper. It may be worth a mention in the  Acoustic emission  article. But I haven't found any evidence of either "Impact spectrometer" or "Impact microscope" as terms being used in the literature. These seem to be neologisms. Per  and an apparent lack of refs discussing these terms, the two articles seem to fail notability guidelines, per , the articles should be deleted
