“…This outcome confirms the beneficial effect of a higher MPO on speech recognition in quiet as reported by Hodgetts et al (2011) and Hol et al (2013). Yet, Gawliczek et al (2020) and Kurz et al (2014) did not find speech recognition in quiet to improve with increasing MPO levels. Gawliczek et al (2020) measured speech recognition in quiet with four different MPO level settings, starting from the highest possible level of the BCHD and decreasing in 6-dB steps.…”

The absence of a significant MPO effect in the study of Gawliczek et al (2020) may be attributed to a ceiling effect since most of their participants had a word recognition score exceeding 90% in each of the four MPO conditions.…”

The absence of a significant MPO effect in the study of Gawliczek et al (2020) may be attributed to a ceiling effect since most of their participants had a word recognition score exceeding 90% in each of the four MPO conditions. In the present study, aiding with the lower MPO device did not result in a ceiling effect, which left room for further speech recognition improvement with the high MPO device.…”

“…To the best of our knowledge, only a few studies have investigated the impact of MPO on speech recognition performance with BCHD. Gawliczek et al (2020) recruited BCHD users who were diagnosed with a conductive or mixed hearing loss. Speech recognition was measured in quiet and in noise with four different MPO level settings, starting from the highest possible level and decreasing in 6-dB steps.…”

“…Speech recognition was measured in quiet and in noise with four different MPO level settings, starting from the highest possible level and decreasing in 6-dB steps. The results showed that patients whose SNHL exceeding 35 dB HL had better speech recognition in noise at higher MPO levels (Gawliczek et al 2020). Increasing the MPO from the lowest to the highest MPO level resulted in a significant average improvement in speech reception threshold (SRT) of 3.2 dB SNR.…”

Objective: To investigate the influence of maximum power output of bone conduction hearing devices on speech recognition in quiet and in noise in experienced users of bone conduction hearing devices. Design: Prospective, randomised cross-over investigation comparing speech recognition performance, subjective sound quality, and device preference between two bone conduction hearing devices with different maximum power outputs. Study sample: Sixteen adult subjects with conductive or mixed hearing loss. Results: Both speech recognition in quiet and speech recognition in noise improved significantly when using the device with high vs. lower maximum power output. Mean improvement in word recognition score in quiet was 10.5% and the mean speech reception threshold in noise improved by 0.9 dB SNR. Compared to the device with lower maximum power output, the sound quality was rated significantly higher with the device with high maximum power output, which was also the device of preference for 81% of the subjects. Conclusion: Bone conduction hearing devices with higher maximum power output have the potential to improve speech recognition in both quiet and noisy listening environments.

A cochlear implant is a neuroprosthetic device that can restore speech perception for people with severe to profound hearing loss. Because of recent evolutions, a growing number of people with a cochlear implant have useful residual acoustic hearing. While combined electro-acoustic stimulation has been shown to improve speech perception for this group of people, some studies report limited adoption rates. Here, we present electro-vibrational stimulation as an alternative combined stimulation strategy that similarly targets the full cochlear reserve. This novel strategy combines the electrical stimulation by the cochlear implant with low-frequency bone conduction stimulation. In a first evaluation of electro-vibrational stimulation, speech perception in noise was assessed in 9 subjects with a CI and symmetrical residual hearing. We demonstrate a statistically significant and clinically relevant improvement for speech perception in noise of 1.9 dB signal-to-noise ratio. This effect was observed with a first prototype that provides vibrational stimulation to both ears with limited transcranial attenuation. Future integration of electro-vibrational stimulation into one single implantable device could ultimately allow cochlear implant users to benefit from their low-frequency residual hearing without the need for an additional insert earphone.
