Disclosed are a hearing aid, an operation method thereof and a corresponding data processing device. The hearing device includes: first and second microphones (MBTE1, MBTE2) for converting input sound into first and second electrical input signals (IN1, IN2); and an adaptive beamformer filter unit ( BFU), configured to adaptively provide a synthesized beamforming signal ( YBF). The adaptive beamformer filter unit (BFU) includes a smoothing unit configured to change with time according to the covariance of the first and second electrical input signals (IN1, IN2), as the time constant for smoothing changes, adaptively changing and smoothly adaptively elements of the covariance matrix to provide an adaptively smoothed covariance matrix. The adaptive beamformer filter unit (BFU) is configured to determine the beamforming signal (YBF) using the adaptively smoothed covariance matrix. 本申请公开了听力装置及其运行方法和相应数据处理系统，其中所述听力装置包括：第一和第二传声器(MBTE1,MBTE2)，用于将输入声音分别转换为第一和第二电输入信号(IN1,IN2)；及自适应波束形成器滤波单元(BFU)，配置成基于所述第一和第二电输入信号(IN1,I
