From: A semisoft thresholding method based on Teager energy operation on wavelet packet coefficients for enhancing noisy speech

Listener Spectral subtraction Wiener filtering MMSE Proposed method
1 3.5 3.3 3.8 4.0
2 2.6 2.5 3.3 3.9
3 3 2.8 3.5 3.8
4 3 2.9 3.6 3.7
5 3.2 3.2 3.6 3.9
  1. Performance comparison of the mean scores of BAK scale evaluated for different methods in the presence of babble noise at a SNR of 10 dB.
