This paper presents the design and assessment of an active musician’s hearing protection device focusing on occlusion effect reduction through active noise control. The system is designed to adapt its feedback compensation to achieve a specified target performance across users, regardless of their ear canal acoustic properties. The detailed design process of the prototype earpiece and feedback compensation algorithm are presented, validated, and implemented. Experimental measurements show the system is able to maintain robust and stable occlusion effect reduction despite great variation in the acoustic properties of an adjustable ear simulator.
