Frequency Response Correction TRIZ Cases
- Adaptive Vehicle Approach Sound Control Under SPL Limits
Vehicle data selects sound sources, filter settings, and control parameters to keep approach alerts audible within sound pressure limits.
- Vehicle Traveling Sound Control Based on Occupant Mood
Traveling sound is tuned to occupant mood and accelerator input, adjusting tone, pressure, and followability to improve in-cabin comfort.
- Audio Signal Correction for Transducer Frequency Matching
Integral and derivative audio pre-correction aligns loudspeaker and microphone frequency response to reduce transducer distortion and improve fidelity.
