Mixing Point and Total Masking Are Equally Effective

I usually don't bother with TRT but this study may interest some: http://journals.lww.com/ear-hearing..._Retraining_Therapy___Mixing_Point_and.3.aspx

 

am i reading this study right ???...it seems to say that total masking does not hinder habituation

from the study

"Results: After 12 months, in the counseling group, three of 18 patients benefited significantly, in the mixing-point group, six of 19 patients benefited, and in the total masking group, four of 11 patients benefited from the treatment. The average decrease in the questionnaire was 16.7% for the counseling group, 31.6% for the retraining group, and 36.4% for the total masking group. No significant average differences among groups were observed."

i must be missing something

wow
