Acoustic Lab

The ASE Acoustic Laboratory (A-Lab) is dedicated to providing electro-acoustic device characteristics design, analysis and characterization in terms of simulation and measurement techniques. ASE A-Lab works closely with customers for the electro-acoustic device design optimization, module analysis, active noise cancellation (ANC) tuning and hearing aid tuning, and electro-acoustic device solutions.

ASE A-Lab can provide complete acoustic information that allows manufacturers to better understand the characteristics of products, thereby improving the overall product quality.
