1. Monitoring of machines, plants and tools
(whistling, grinding, humming, buzzing)
e.g.: identification of "tool in cutting", return stroke of press, leakage

2. Process monitoring
(bangs, hissing, sizzling)
e.g.: electrode breakage with arc welding, abrasive proportion with jet cutting, packaging machines

3. Monitoring of assembly processes
(locking, snapping)
e.g.: assembly of connectors, locking in place of retaining rings, snap-in casing assembly

4. Identification of material breakage
(cracking, splitting)
e.g.: manufacture of veneers, glass breakages

5. Equipment testing
e.g.: keyboard click, sound emissions with switching operations

6. General sound level monitoring
e.g.: room monitoring
