Claim 8:
9. A method for controlling the noise that an operator hears when operating a machine, the method comprising:
detecting sounds, using one or more of a microphone or another sensor configured for detecting sound vibrations or other operational parameters that result in the generation of sound vibrations during operation of the machine;
wherein the machine is a vibratory compactor, and the method includes detecting vibrations transmitted to machine parts or components of the machine by a vibratory drive shaft configured to introduce various vibration frequencies to compactor drums of the vibratory compactor;
identifying preselected sounds from the detected sounds that a machine operator does not want to hear during operation of the machine; and
selectively cancelling only the preselected sounds the machine operator does not want to hear while operating the machine by generating an anti-noise signal to interfere with the preselected sounds.
