Acoustic Lab
Overview
The ASE Acoustic Lab (A-Lab) designs, analyzes and characterizes electro-acoustic devices through simulation and measurement.
A-Lab works with customers on device design optimization, module analysis, active noise cancellation (ANC) and hearing-aid tuning, and complete electro-acoustic solutions, giving manufacturers the acoustic detail to improve product quality.
