Eligibility
Age
18 Years to 64 Years
Inclusion criteria
Inclusion criteria: - Mixed hearing loss, minimum bone conduction (BC) thresholds of 15 dBHL at 2 or more frequencies and maximum BC thresholds of 35 dBHL (average 1,2,4 kHz) to avoid differences between fitting rules becoming smaller or even non-existent because the required gain or output cannot be achieved due to device limitations, for one or more fitting rules. - At least 3 months of BCD-use - Average air conduction thresholds at the contralateral side are at least 10 dB worse than the averaged unmasked BC thresholds, to prevent that the contralateral ear determines the outcomes. - Capable to answer questions on a smartphone. - Fluent in Dutch. - Minimum aided free-field word score with BCD of 85% at 65 dB SPL (for speech recognition tests).
Exclusion criteria
Exclusion criteria: - Single-sided deafness application of the BAHA. - Reporting hyperacusis or severe sound sensitivity. - Balance problems that result in suffering from motion sickness when wearing a VR headset - Astigmatism (curvature of the cornea), because this makes it impossible to see in 3D when looking through a VR headset. - The gain needed for each of the three gain prescriptions at 65 dBSPL input cannot be applied within ± 3dB at two or more octave frequencies up to 4 kHz. - At least one of the three gain prescriptions is unacceptable for the participant or does not result in sufficient speech perception during a first check in the VR environment. - The compliance with the scheme of program selection was too low.
