A wafer-level package that employs one or more integrated hydrogen getters within the wafer-level package on a substrate wafer or a cover wafer. The double talk detector declares near-end speech to be present if an estimated power level of the upper band signals exceeds the upper adaptive decision threshold value, and declares the near-end speech to be absent if the estimated power level of the upper band signals falls below the lower adaptive decision threshold value for a predetermined number of iterative cycles. The cavity and the front frame include metal sheet.
