Sound Producing Devices TRIZ Cases
- Acoustic Intensity Vector ANC With Dual Error Microphones
Dual error microphones calculate an acoustic intensity vector to adjust adaptive noise cancellation algorithms.
- Adaptive Stabilization Coefficient for Active Vibratory Noise Control
An active vibratory noise reduction system uses an adaptive stabilization coefficient updating unit to generate control signals.
- Active Noise Cancellation for Urban Air Mobility Propellers
A noise canceling device predicts acoustic wave amplitude using propeller RPM and location data to generate anti-phase sound waves.
