Active masking of tonal noise using motor-based acoustic generator to improve sound quality

A system comprising:

• a motor generating a tonal noise;
• and
• an active masking acoustic signal generator (AMAG) configured to at least facilitate:
• generating complementary tones with respect to the tonal noise, the complementary tones comprising low-order overlapping harmonics with respect to the tonal noise;
• and
• masking the tonal noise, by introducing the complementary harmonic tones, including the low-order overlapping harmonics with respect to the tonal noise, including the low-order overlapping harmonics with respect to the tonal noise.

A vehicle comprising:

• a drive system including a motor generating a tonal noise;
• and
• an active masking acoustic signal generator (AMAG) configured to at least facilitate:
• generating complementary tones with respect to the tonal noise, the complementary tones comprising low-order overlapping harmonics with respect to the tonal noise;
• and
• masking the tonal noise, by introducing the complementary harmonic tones, including the low-order overlapping harmonics with respect to the tonal noise, including the low-order overlapping harmonics with respect to the tonal noise.
