Positive TEN test
A masked threshold is at least 10 dB or more above the level of the TEN
Masked threshold is at least 10 dB above the non-masked threshold
Clinical Value of TEN test
If dead regions are present, this may have important implications for fitting hearing aids and for predicting the
likely benefit of hearing aids. When a patient has a dead region, there may be little or no benefit from hearing
aid amplification for frequencies well inside the dead region (Moore 2009).
Identifying a cochlear dead region can:

Help counsel the patient and manage expectations regarding the potential benefit of hearing
aids

Helps on choice of type of hearing aid

Can help determine if a patient would be a good candidate for cochlear implants
o Patient might do better with an implant when there are extensive dead regions
o Helps determine insertion depth
