+function test_speechInNoise
+% test_MAP1_14 is a general purpose test routine that can be adjusted to
+% test a number of different applications of MAP1_14
+%
+% A range of options are supplied in the early part of the program
+%
+% One use of the function is to create demonstrations; filenames <demoxx>
+%  to illustrate particular features
+%
+% #1
+% Identify the file (in 'MAPparamsName') containing the model parameters
+%
+% #2
+% Identify the kind of model required (in 'AN_spikesOrProbability').
+%  A full brainstem model (spikes) can be computed or a shorter model
+%  (probability) that computes only so far as the auditory nerve
+%
+% #3
+% Choose between a tone signal or file input (in 'signalType')
+%
+% #4
+% Set the signal rms level (in leveldBSPL)
+%
+% #5
+% Identify the channels in terms of their best frequencies in the vector
+%  BFlist.
+%
+% Last minute changes to the parameters fetched earlier can be made using
+%  the cell array of strings 'paramChanges'.
+%  Each string must have the same format as the corresponding line in the
+%  file identified in 'MAPparamsName'
+%
+% When the demonstration is satisfactory, freeze it by renaming it <demoxx>
