Active noise cancellation (ANC) technology is a valuable asset for hearables. For a well performing and robust ANC system precise knowledge of the relevant acoustic paths is vital. It is feasible to individually measure the user’s secondary path by using the inner loudspeaker and microphone that are…
The headphones market is expanding and new applications based on active noise control (ANC) are emerging. In this contribution, we derive a fixed feed-forward FIR filter for ANC headphones based on a minimum mean-square error (MMSE) cost function that realizes user-defined active equalization and at…
Occluding the ear canal alters the perception of the own voice. This is called the occlusion effect. Low frequency components of the own voice are amplified and high frequency components are attenuated. In this contribution, we extend our previously published Active Occlusion Cancellation (AOC) syst…
