For the development of high end headphones numerical simulation of headphone acoustics is an efficient tool. While discrete element models give good results for frequencies up to a few kilohertz finite element models are valid for higher frequencies too. A headphone model using finite elements and boundary elements was built in three phases both numerically and as a real world sample. The validity of the model was verified by comparison of both the radiated sound field and the membrane modal behaviour using a scanning laser vibrometer. Excellent agreement between measured and computed amplitude frequency responses was achieved.
