Abstract
An earpiece adapts to the acoustics characteristics and needs of its user to provide a perceptually transparent hearing protection, apart from uniform loudness reduction. An occlusion effect (OE) active noise control (ANC) system reduces the augmented perception of one's own voice while occluded. This occlusion effect active control adapts to the specific acoustic characteristics of the user to provided better control of the details occlusion effect reduction, and enhanced performances relative to fixed or one-size-fits-all solutions. An isolation effect (IE) filtering algorithm adapts itself to the user's acoustic characteristics to provide a uniform attenuation either in dB or in phons. Additionally, the device may be used as an in-ear monitor that also adapts to its user characteristics to provide in-ear quality sound.
