Two source localization arrays based on the far field beamforming method.
This arrays enable an octave band analysis of the different aeroacoustic sources outside the vehicle: rear view mirror, door handle, wheelhousing…
| Method | Far field beamforming |
| Microphones number | 64 (side/vertical) and 88 (top/horizontal) |
| Frequency range | 630Hz– 8KHz |
| Output data | Sound level and acoustic intensity map calculated on the source surface |
| Resolution (source separation capability) | 17cm at 2KHz |
