Abstract
Objective: Efficacy of insert and supra-aural earphones during visual reinforcement audiometry (VRA) was investigated for 12- to 24-month-old children. Design: VRA testing began in the soundfield and transitioned to either insert or supra-aural earphones. Audiologists recorded threshold estimates, participant behaviors, and an overall subjective rating of earphone acceptance. Study sample: One hundred and eighty-six 12- to 24-month-old children referred to the Department of Audiology at St. Louis Children’s Hospital for a variety of reasons. Results: Subjective ratings indicated high acceptance of insert earphones (84%) and supra-aural earphones (80%) despite negative behaviors. There was no significant difference in the number of threshold estimates based on earphone type for 12- to 17-month-old participants. Participants in the 18- to 24-month-old age group provided significantly more threshold estimates with insert earphones (mean = 5.3 threshold estimates, SD = 3.5) than with supra-aural earphones (mean = 2.9 threshold estimates, SD = 2.9). All seven participants who rejected earphone placement were successfully reconditioned for soundfield testing. Conclusions: Data support the use of insert earphones during VRA, especially with 18-to 24-month-old children, to obtain ear-specific information.
