摘要： A sound control device includes an obtainer and a determiner. The obtainer obtains performance information including sound pitch information indicating a sound pitch and sound volume information indicating a sound volume detected as a continuous quantity. The determiner determines a note start and a note end based on a comparison between the sound volume and a sound-volume threshold and based on a change in the sound pitch. Upon determining that there is a predetermined way of change in the sound volume, the determiner determines a time of the change as the note end and determine the time as the note start, irrespective of the comparison between the sound volume and the sound-volume threshold.

摘要： A sound generator (1) includes a casing (10) with at least one exhaust gas inlet (11) and at least one exhaust gas outlet (12) that is different from the at least one exhaust gas inlet (11) and at least one electro-acoustical transducer (20). The electro-acoustical transducer (20) is configured to produce sound in dependence on an electrical control signal. The electro-acoustical transducer (20) is located within the casing or directly attached to the casing. An active noise control system (9) includes the sound generator (1). A vehicle (8) with an internal combustion engine (6) includes the active noise control system (9).

摘要： A Harmonic Generator for audio applications and a Pre-Amplifier circuit are combined to form a Harmonic Generator and Pre-Amplifier circuit. The Harmonic Generator is formed from a Buffer Circuit responsive to an input program signal for buffering the input program signal and for providing a buffered input program signal A Modulator Circuit is coupled to receive the buffered input program signal and generates harmonics in response to changes in amplitude of the program input signal to provide a modulated input program signal. A Summing Circuit adds the buffered input program signal and the modulated input program signal to provide a composite modulated input program signal. The Pre-Amplifier is coupled to receive the composite modulated input programing signal and process the signal in three audio frequency bands to provide a compensated output signal that includes harmonics generated by the modulator.
