% find the  threshold for a tonecomplex  consisting of a sequence of 10-ms tones

%   whose frequencies are chosen at random from a list (OHIOfrequencies)

% All tones are presented at the same level (SL) computed using absolute

%   threshols specified in OHIOthresholds;

% The duration of the complex is increased across runs and the number of tones is

%   controlled by OHIOdurations, (for each 20 ms a further tone is added.

% The frequency of the tones is changed on each trial

% fetch thresholds and frequencies
