Appropriate and adequate fitting of acoustic and electric parameters are important for optimising EAS benefit. The acoustic cut-off or cross-over frequency is one key parameter that can affect speech perception outcomes and device use significantly (Yoon et al. 2019; Gifford et al. 2017). The acoustic cut-off frequency is often determined using the unaided acoustic (audiometric) thresholds in the implanted ear. Based on the age and abilities of the child, audiologists utilise a mix of behavioural techniques like Behavioural Response Audiometry, Visual Reinforcement Audiometry and Conditioned Play Audiometry to measure audiometric thresholds (Nielsen and Olsen 1997). Measurement of reliable and valid acoustic thresholds via these behavioural thresholds can be challenging and time consuming. Test fatigue in the paediatric population can be high with tasks that require compliance and can deplete their attention for CI programming processes. The need to switch rooms or test environment can also affect the children’s ability to attend or focus. Reducing the need to move between the sound-booth and programing room can help ensure a smooth clinical workflow with children. Children with developmental delays or other challenges further add to the difficulty of obtaining accurate behavioural thresholds for fitting, potentially impacting optimal EAS outcomes.

Children categorised as having bilateral NH with no language delay were included in the control group. All subjects in the control group received hearing screening before participation in the study to confirm NH. For pure-tone hearing screening, children participated in conditioned play audiometry using 1000-, 2000-, and 4000-Hz tones presented at 20 dB HL. A child was considered to pass the audiometry test if 2 of 3 reliable responses were obtained at 20 dB HL for all 3 frequencies in both ears (Association AS-L-H 1997). Children underwent the Denver Developmental Screening Test II (DDST-II) to screen developmental status. The DDST-II is a developmental screening scale in four areas: gross motor, language, fine motor-adaptive, and personal-social (Epir and Yalaz 1984). There were no developmental delays in any area or hearing loss in the control subjects.
