How does the TEN (HL) Test work?
To perform a TEN test, first you obtain the patient's pure-tone threshold levels between 500 and 4000 Hz using either the tones available on the TEN (HL) CD or by using the built-in tones available on your clinical audiometer.
After the pure-tone audiogram is obtained, the TEN noise is added to each frequency of the pure-tone signal with a level 10 dB above that of the threshold. Both the tone and the noise are presented to the same ear of the patient. If the masked threshold is 10 dB above that of both the threshold and the TEN noise, the cochlea is considered "dead" at that frequency.
The TEN (HL) test was developed at the University of Cambridge by Dr. Brian CJ Moore.
