Headphone Simulation Results - Absorbent Cushions

Headphone Simulation Results with Cushions

Many circumaural headphones employ cushions that are compliant and breathable and applying appropriate acoustical properties to the cushions add realism to the model.  The simulations below compare the enclosed case (seen in the previous page) to a situation where acoustic waves are permitted to pass through a highly resistive cushion and propagate into acoustic half space.

 


 

The animations below clearly illustrate the extended model with the sound-waves propagating through the resistive cushion and into the surrounding air.
