Spectral recognition of percussive sounds

A system for detecting and correlating percussive sounds with previously identified spectral signatures of a plurality of events so as to notify a user of an occurrence of a particular event, wherein the system comprises:

• at least one processor;
• and
• at least one non-transitory machine readable medium having instructions thereon, the instructions executable by the at least one processor to at least:
• determine when ambient noise periods are occurring;
• automatically determine a predefined amplitude threshold based at least in part on various electrical signals received during the ambient noise periods;
• receive an electrical signal from a transducer;
• determine if the electrical signal indicates that a percussive sound associated with the electric signal exceeds the predefined amplitude threshold;
• produce a data signal based on the electrical signal only when the percussive sound exceeds the predefined amplitude threshold;
• compare the data signal to at least one reference signal;
• and
• send a notification to a user based at least in part on the data signal correlating to at least one reference signal.

A method for detecting and correlating percussive sounds with previously identified spectral signatures of a plurality of events so as to notify a user of an occurrence of a particular event, wherein the method comprises:

• coupling a transducer of a system for detecting and correlating percussive sounds with a surface that is to be monitored for percussive sounds;
• detecting a vibration of the surface that is to be monitored for percussive sounds using the transducer;
• generating, by the transducer, an electrical signal based on the detected vibration;
• receiving an electrical signal from the transducer;
• producing a data signal based on the electrical signal;
• comparing the data signal to at least one reference signal;
• and
• sending a notification to a user based at least in part on the data signal correlating to at least one reference signal.
