What is the latest hearing test being used in children?

One of the newest tests being utilized is the auditory steady state response (ASSR) evaluation. This is a test that is used in conjunction with the ABR. It is completed while the child is sleeping, or sedated, and it makes recordings from the auditory nerve as the response travels up to the brainstem. The generators for this test are commonly accepted to be similar to those of the ABR. One advantage of ASSR is that the stimuli used to test the child's hearing are more frequency-specific, which allows the audiologist to predict hearing levels for a wide range of sounds with increased accuracy. In addition, the ASSR is faster and has the ability to test at levels somewhat louder than the ABR (due to equipment limitations of the ABR), making the distinction between severe and profound losses more clear. It should be noted, however, that results for a mild hearing loss and normal hearing are indistinguishable from each other, so there is potential for a misdiagnosis for children with mild hearing loss.
