&lt;br /&gt;
The modal value of the thresholds of hearing at a specified frequency of an adequately large number of otologically normal subjects within the age limits of 18 to 25 inclusive.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Note: 1 Measured sound pressures should be converted to the corresponding sound pressure levels in decibels before the modal value is taken.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Note: 2 An otologically normal subject is a person in a normal state of health who is free from all signs or symptoms of ear disease and from wax in the auditory canal.&lt;br /&gt;
