Acoustical or vibrational monitoring in a guided assembly system

A monitoring and inspection system for a work area in an assembly line comprises:

• a first microphone configured to sense sounds generated in a work area;
• a processor configured to receive acoustic signals from the first microphone;
• wherein the processor is configured to analyze the received acoustic signals and to compare received acoustic signals received during the performance of a first operational step performed in the work area;
• wherein the processor is configured to identify a particular acoustic signature that most closely matches the received acoustic signals, and verifying that the identified acoustic signature is an acoustic signature associated with the first operational step;
• and
• wherein the processor is further configured to confirm that the first operational step is correctly completed by confirming that the acoustic signature associated with the first operational step has been performed.

A method for determining an acoustic signature for a particular operational step performed in a work area, wherein the method comprises:

• monitoring, with a microphone, a work area;
• performing a plurality of iterations of a first operational step in the work area;
• producing, with the microphone, an acoustic signal during each iteration of the first operational step;
• and
• determining, with a processor, an acoustic signature associated with the first operational step based upon the acoustic signals produced during the iterations of the first operational step.
