LTQ

LTQ(bark_axis, reference='zwicker')

Calculate the level threshold in quiet over bark_axis

Linear interpolation from the data given in E. Zwicker, H. Fastl: Psychoacoustics. Springer, Berlin, Heidelberg, 1990. (figure 2.1) SPL is given for a free-field condition relative to 2 × 10−5 Pa (Threshold for roughness is slightly different)

Parameters:

• bark_axis (numpy.array) – Frequency axis in bark to compute the threshold

• reference (str()) – ‘zwicker’ or ‘roughness’
