Background and Objectives Assessing accurate audiometry might be an important index treating patients with hearing loss. So far there have been no studies on analysis of correlations between pure tone audiometry (PTA) and auditory steady-state response (ASSR) for children in Korea. We analyzed correlations between PTA and ASSR in order to investigate the usefulness of ASSR. Subjects and Method Past medical records were retrieved from the patients who visited Department of Otolaryngology at Tertiary Referral Hospital from January 2012 to December 2012 and underwent the correlation study between ASSR and PTA with a correlation analysis of frequency. The participants over the age of 15 were classified into the adult group and those below in the children group. Results There was a statistically significant correlation between the average hearing threshold of ASSR and PTA (correlation coefficient=0.934). There was a strong correlation between children and adult group, too. With the frequency range of 500, 1000, 2000, and 4000 Hz, the correlation coefficients were 0.875, 0.896, 0.915, and 0.900, respectively. The degree of hearing loss was classified by using PTA follows: below 25 dB as normal; between 26-55 dB as moderate hearing loss; above 56 dB as severe hearing loss. Correlation coefficients for the above hearing ranges were 0.527, 0.670, and 0.744, respectively. Strong correlation was found between children and adult group, too. Conclusion The comparison results between the average hearing threshold of ASSR and PTA indicated that the threshold of ASSR could well reflect the results of both children and adult group.

Abstract
Background and Objectives Assessing accurate audiometry might be an important index treating patients with hearing loss. So far there have been no studies on analysis of correlations between pure tone audiometry (PTA) and auditory steady-state response (ASSR) for children in Korea. We analyzed correlations between PTA and ASSR in order to investigate the usefulness of ASSR. Subjects and Method Past medical records were retrieved from the patients who visited Department of Otolaryngology at Tertiary Referral Hospital from January 2012 to December 2012 and underwent the correlation study between ASSR and PTA with a correlation analysis of frequency. The participants over the age of 15 were classified into the adult group and those below in the children group. Results There was a statistically significant correlation between the average hearing threshold of ASSR and PTA (correlation coefficient=0.934). There was a strong correlation between children and adult group, too. With the frequency range of 500, 1000, 2000, and 4000 Hz, the correlation coefficients were 0.875, 0.896, 0.915, and 0.900, respectively. The degree of hearing loss was classified by using PTA follows: below 25 dB as normal; between 26-55 dB as moderate hearing loss; above 56 dB as severe hearing loss. Correlation coefficients for the above hearing ranges were 0.527, 0.670, and 0.744, respectively. Strong correlation was found between children and adult group, too. Conclusion The comparison results between the average hearing threshold of ASSR and PTA indicated that the threshold of ASSR could well reflect the results of both children and adult group.
