Single monotic auditory steady-state response in children with severe to profound sensorineural hearing loss




The aim of the study was to find out the predictive value of single monotic auditory steady-state response (ASSR) in hearing threshold estimation in children with severe to profound sensorineural hearing loss (SNHL).

Materials and methods

Forty-eight children (96 ears) with severe to profound SNHL were included. They were subjected to age-based audiological evaluation. Single monotic ASSR was obtained and analyzed for all children using test signals of 250, 500, 1000, 2000, and 4000 Hz, modulated in either ears at high rates of 67, 74, 81, 88, and 95 Hz, respectively, using GSI Audera evoked potential system.


The number and percentage of ASSR detected were highest at 1000, 500, and 2000 Hz, respectively in all children. The ASSR thresholds obtained were statistically correlated with the behavioral audiometric thresholds at the corresponding frequencies. A considerable number of ears with no sound field thresholds or click auditory brainstem response responses showed ASSR.


Single monotic ASSR, with high modulation frequencies, has shown to be a reasonable method for estimating hearing sensitivity in the mid-conventional audiometric frequencies in children with severe to profound SNHL.
