Estimation of attack time constant for dynamic range compressors in hearing aids

18 band ANSI S1.11 filter bank based on interpolated finite impulse response technique for hearing aids

“…Post implementation core power results are given in Table 9 for a supply voltage of 1.2 V. The FB architecture consumes a total power of 0.37 mW. The FB algorithm was combined with a single channel DRC [25] and tested with a sample audio file for flatband condition and without any compression applied. The input and reconstructed output waveforms are shown in Fig.…”
