Abstract:
According to an example aspect of the present invention, there is provided a Method for regularizing the inversion of a stereo headphone transfer function for headphone equalization, characterized by using the equation for the equalization: H S   1 - 1  ( ω ) = H *  ( ω )  H  ( ω )  2 + β ^  ( ω )  D  ( ω ) = H *  ( ω )  H  ( ω )  2 + [ α  ( ω ) + σ 2  ( ω ) ]  D  ( ω ) . in which equation H SI −1 (ω) is sigma inversion H*(ω) is complex conjugate of a response D(ω) is a delay filter introduced to produce a causal inverse H RI −1 (ω) H*(ω) a response α(ω) is headphone reproduction bandwidth, σ(ω) an estimation of the regularization needed inside that bandwidth.

Claim (Index 21):
The system in accordance with  claim 17 , wherein each driver or ear cup of the headphone is factory calibrated against a set reference ear cup or driver and stored in a memory of the amplifier, whereby the factory calibration makes all of the ear cups in the headphone system acoustically essentially the same, e.g. same response, same loudness based on set reference ear cup or driver.
