Purpose The present study aimed to measure hearing sensitivity in young adults with normal hearing using a 40-Hz auditory steady-state response with CE-Chirp and to evaluate the speed and accuracy of this method.

Method Twelve young adults (1 man, 11 women; mean age = 22.1 ± 3.1 years) each completed two auditory steady-state response measurement sessions with CE-Chirp. The difference score was calculated at each of the four pure-tone frequencies. The measurement time and residual noise level in all stimulus levels were also determined.

Results The difference scores across the 4 frequencies ranged within ±10 dB (1st: 58% to 71%, 2nd: 54% to 79%), within 20 dB (1st: 79% to 96%, 2nd: 79% to 100%), and ≥ 30 dB (1st: 4% to 17%, 2nd: 0% to 17%). The measurement times for both ears were approximately 20 min in both sessions. There was a significant correlation between the measurement time and the mean residual noise level for pooled frequencies in all stimulus levels (p = .0001249, r = .70). The measurement time was reduced by approximately 50% from conventional auditory steady-state response measurement.

Conclusion The results of this preliminary study support the use of this technology as a rapid and accurate method for behavioral auditory threshold evaluation.
