Hearing thresholds of COR audiometry in 59 young children with sensorineural hearing loss were compared with those of play audiometry in follow-up observation. Test frequencies were 500, 1000 and 2000Hz, and the intervals between the two tests were ranged from less than 1 year to more than 5 years.
The test-retest agreement within the limits of ±15dB was achieved in 80% of the total 150 paires of thresholds. The agreement, however, decreased significantly (62.5%) when the COR audiometry was performed in young children aged less than 2 years.
The difference between the average thresholds of the COR and play audiometry was only 0.2dB. The results suggested that insidious progression of deafness during the period of the tent-retest interval canceled the physiological development of hearing in infants and young children.
