Fastener driving operation result detector

A fastener driving system, the system comprising:

• a fastener driving tool configured to drive a fastener through a covering material and into an underlying framing member, wherein the fastener tool generates sound upon driving the fastener through the covering material;
• an acoustic transducer configured to capture the sound generated by the fastener driving tool;
• and
• processing circuitry configured to:
• generate an audio signal based on the captured sound;
• analyze a frequency spectrum of the audio signal to generate a frequency spectrum analysis;
• based on the frequency spectrum analysis, determine whether the fastener hit or missed the underlying framing member;
• and
• generate an indication of the determination.

A method of determining a result of a fastener driving operation, the method comprising:

• capturing sound generated by operation of a fastener driving tool attempting to drive a fastener through a covering material and into an underlying framing member;
• generating an audio signal based on the captured sound;
• analyzing at least a portion of a frequency spectrum of the audio signal to generate a frequency spectrum analysis;
• based on the frequency spectrum analysis, determining whether the driven fastener hit or missed the underlying framing member;
• and
• generating an indication of the determination.

A computer implemented method for determining a result of a fastener driving operation, the method comprising:

• capturing sound generated by operation of a fastener driving tool attempting to drive a fastener through a covering material and into an underlying framing member;
• generating an audio signal based on the captured sound;
• comparing at least a portion of a frequency spectrum of the audio signal to a stored threshold frequency;
• based on the frequency spectrum comparison, determining whether the driven fastener hit or missed the underlying framing member;
• and
• generating an indication of the determination.
