“…For decades, the most reliable objective diagnostic method in pediatric audiology was click-evoked auditory brainstem response (c-ABR) with a non-filtered click as stimulus. There is empirical confirmation that a non-filtered click c-ABR highly correlates with an average hearing threshold determined by pure tone audiometry in 2-4 kHz range [5][6][7][8][9] . Unfortunately, estimation of c-ABR threshold does not provide information on hearing threshold below 2 kHz.…”

Current recommendations proposed by pediatric audiologists are to commence with hearing amplification in children aged 6 months and above, after previous determination of the type and degree of hearing impairment and audiometric configuration. The goal of this study was to compare results obtained by click-evoked auditory brainstem response (c-ABR) and auditory steady state response (ASSR) in a group of children. This study included 68 children with different degrees of hearing impairment evaluated by c-ABR and ASSR. It is well-known that the c-ABR threshold highly correlates with behavioral hearing level at 2 kHz. In our study, the correlation between the c-ABR and ASSR thresholds in the whole sample was 0.58, 0.73, 0.97, 0.96, 0.95, 0.97; in the group of children with c-ABR thresholds up to 40 dBHL, it was 0.42, 0.73, 0.86, 0.74, 0.81, 0.81; and in the group with c-ABR thresholds worse than 40 dBHL, it was 0.46, 0.56, 0.89, 0.83, 0.85, 0.89 at 0.5, 1, 2, 4, 1-4, 2-4 kHz, respectively. Individual differences between the c-ABR and ASSR thresholds in the whole sample were up to 95, 90, 20, 25 dB at 0.5, 1, 2, 4 kHz, respectively. Study results indicated that there was strong correlation between the c-ABR and ASSR thresholds at 2, 4, 1-4, 2-4 kHz. The ASSR can be used as a valuable clinical tool and an excellent complementary method which, along with other audiologic techniques, provides more accurate hearing threshold estimation at an early age in children.

Objective: The current study examined the frequency specificity of NB chirps by comparing the spectral characteristics of 500-, 1000-, 2000- and 4000-Hz NB CE-Chirp LS® stimuli with those of 2-1-2 tones. Design: Spectral characteristics including the center frequency, main lobe bandwidth, and stimulus energy changes after stopband filtering were compared. The bandwidth was computed as the difference between the upper and lower frequencies at -20 dB cutoff points of the main lobe; the centre frequency was determined as the geometric mean of the upper and lower frequencies at the -20 dB cutoff points. Results: At 100 dB peSPL, the mainlobe bandwidths of the 500, 1000, and 2000 Hz NB CE-Chirp® LS acoustic spectra were 1.8-1.9 times wider than the acoustic spectra for the 2-1-2 tones; the 4000 Hz NB CE-Chirp® LS bandwidths were 1.4-1.5 times wider than those of the 2-1-2 tones. The energy of NB CE-Chirp® LS stimuli was concentrated within ±0.75 octave of the center frequency, compared to ±0.5 octave for 2-1-2 tones. Conclusion: NB CE-Chirp® LS stimuli demonstrated poorer frequency specificity compared with 2-1-2 tones. Further studies are needed to investigate the place specificity of the ABRs to NB CE-Chirp® LS before implementing them clinically.
