For characteristic analysis of the 24 KHz audio, the 10-ms, 18-band quasi-ANSI filter bank has been proposed and designed for advanced hearing aids. To greatly reduce the computation complexity, several time-domain multirate signal processing techniq

Recently, emerging mobile computing requires the high integration of hearing aids into a single system-on-chip. Modern hearing aid systems include a frequency decomposer, noise reduction, feedback cancellation, auditory compensation, and intelligent

The main contribution of this study is the development of an area-/energy-efficient cascaded direct-truncation (DT) datapath with the so-called static floating-point (SFP) arithmetic to realize a low-delay analysis filter bank (AFB) for digital heari

This paper presents a low-power and real-time noise reduction (NR) algorithm using 18-band 1/3-octave quasi-ANSI filter bank for binaural hearing aids. With aids of binaural cues and minima controlled recursive average (MCRA) approach, the proposed N

The ANSI S1.11 1/3-octave filter bank is suitable for digital hearing aids, but its large group delay and high computational complexity complicate matters considerably. This study presents a 10-ms 18-band quasi-ANSI S1.11 1/3-octave filter bank for p

Due to well matching the frequency characteristics of human ears, ANSI S1.11 1/3-octave filter bank is popular in acoustic applications, such as acoustic analyzers and equalizers. It is also desirable in hearing aids because the famous hearing aid pr

This paper presents a low-power hearing aid chip which operates under near-threshold voltage region to minimize energy consumption. The proposed variable-latency design technique compensates the performance degradation under ultra-low voltage, while

This paper presents the multirate and re-sampling techniques to realize a low-delay, 18-band quasi-ANSI filter bank for digital hearing aids, which not only achieves a rather low computation complexity without a significant increase in the latency, b

The ANSI S1.11 1/3-octave filter bank is popular in many acoustic applications because it matches the human hearing characteristics. However, the long group delay and the high computational complexity limit the usage in hearing aids. A Quasi-ANSI S1.

Auditory compensation consumes significant power due to the computation-intensive operations in the filter bank. To reduce the complexity, a controllable filter was designed to replace the filter bank. Filter order was designed to match prescriptions
