AVL Acoustics has developed methodologies for the detection of specific acoustic phenomena. One of these unique methodologies is Active Path Tracking (APT) which offers fast source identification with verification.
Powertrain induced structure-borne noise is often a major factor influencing vehicle interior noise quality and shaping brand image.
Active Path Tracking is a completely new methodology, developed by AVL, for the rapid identification and verification of structure-borne noise paths affecting vehicle interior harmonic noise.
AVL APT uses a novel adaptation of active noise cancellation techniques to the task of source identification.
The AVL APT method is fast and avoids the need to dismantle the test vehicle during data collection. No dismantling means no disturbance to the dynamic behaviour of the vehicle and no risk of damaging rare and expensive prototypes.
