Compared to analog hearing aids (HA), digital HA provide not only signal transformation but also adaptive filtration and reconstruction of the signals. This allows better speech perception in noisy surroundings for patients with neurosensory hypoacusis and recovery of speech perception in persons with partial frequency deafness. The design of digital hearing aids requires utilization of effective signal processors with signal memory. Use of the existing signal processors for such purposes enables construction of hearing aids with digital signal processing having suitable technical and maintenance characteristics.
与模拟助听器相比，数字助听器不仅能进行信号转换，还能对信号进行自适应滤波和重建。这使得患有神经感觉性听力减退的患者在嘈杂环境中能更好地感知语音，也能让部分频率性耳聋患者恢复语音感知能力。数字助听器的设计需要使用具备信号存储功能的高效信号处理器。将现有的信号处理器用于此目的，能够制造出具有合适技术和维护特性的数字信号处理助听器。
