Summary - Clinical evolution of a non-occluding DSP hearing instrumentResults
of these studies support the following conclusions: - New
and existing hearing aid users experience benefit of the amplification provided by the test device fit
according to the Audiogram+ rationale that is equivalent to or better than when fit with devices with
conventional earmoulds or shells.
- The test device with its sound
delivery system is effective in eliminating sensation of occlusion and poor sound quality of the wearer’s
own voice. It was not necessary in any of the fittings carried out in these studies to deal with occlusion-related
complaints.
- The sound delivery system allows adequate fitting of
must adult ears, and provides good comfort and retention of the devices.
- Stabilizer
digital feedback suppression required to ensure stable fittings of hearing loss falling into the fitting
range of this device. Further, the Maximum Stable Gain fitting toll was found to be of great clinical
utility in determining optimum gain settings for stable fittings.
- New
hearing aid users adapt quickly to the test devices.
- Many experienced
hearing aid users with hearing losses within the test device fitting range prefer the test device to
conventionally fit hearing instruments, primarily due to natural sound quality in general, and better
physical comfort.
- The test devices are rated very highly by wearers
in terms of cosmetic appeal.
