1. A method for determining hearing thresholds in the absence of pure-tone testing, comprising: administering an adaptive speech recognition test to an individual and obtaining a test score; calculating a hearing threshold designated as y j for the individual at least at one of the following frequencies, wherein j=0.5, 1, 2, 4, and 8 kHz using the formula 
 y j =b j0 +b j1 x 1 +b j2 x 2 +b j3 x 3 wherein the value for x 1 expressed on a 0 to 100 scale is the test score of the administered adaptive speech recognition test, the value for x 2 is the chronological age of the individual expressed in years, and the value for x 3 is the self-report of perceived hearing handicap/impairment of 1 for yes and 0 for no, wherein at j=0.5 kHz the b j0 , b j1 , b j2 , and b j3 constants are 103.69, −1.23, −0.21, and 7.55, respectively; at j=1 kHz the b j0 , b j1 , b j2 , and b j3 constants are 133.27, −1.59, −0.30, and 9.40, respectively; at j=2 kHz the b j0 , b j1 , b j2 , and b j3 constants are 154.00, −1.92, −0.17, and 7.51, respectively; at j=4 kHz the b j0 , b j1 , b j2 , and b j3 constants are 144.57, −1.84, 0.06, and 11.10, respectively; and at j=8 kHz the b j0 , b j1 , b j2 , and b j3 constants are 122.91, −1.67, 0.38, and 13.57, respectively.
