in the air surrounding the driver inside the headphone\/earphone. Depending on the application and complexity of the headphone design, either a 2D spice model or a full Comsol\u2122 model is built. Using this setup we can quite accurately predict the sound performance and adjust parameters according to the customer&#8217;s wishes.<\/div>\n<\/div><\/section>\n\n<style type=\"text\/css\"
