“…This is unfortunate given the poor objective and subjective speech-in-noise recognition in this group and the limited capabilities of hearing aids (even with directional microphones) to improve communication in adverse listening environments. Remote microphones have been shown to be of very high benefit, improving speech recognition and reducing listening effort in noisy environments (e.g., Wolfe et al, 2015). We strongly encourage patient education in this regard.…”

“…(2013) found that CI users performed better with adaptive digital wireless systems compared with analogue and fixed-gain FM systems in high levels of noise. With CI users, the general benefit from digital RM was confirmed in recent studies by Wolfe et al. (2015) and De Ceulaer et al.…”

Remote microphones (RMs) have been developed to support hearing aid (HA) users in understanding distant talkers. In traditional clinical applications, a drawback of these systems is the deteriorated speech intelligibility in the near field. This study investigates advantages and disadvantages of clinical RM usage and the effects of different directionality settings of the HAs in complex listening situations in the laboratory. Speech intelligibility was investigated in 15 experienced severely hearing impaired participants in a noisy environment using a dual-task test paradigm where the tasks were presented from either a near field or a far field loudspeaker. Primary and secondary tasks were presented simultaneously so attention had to be shared on both tasks. In a second experiment, two speech intelligibility tests were presented from either the near field or the far field loudspeaker. The tests were interleaved to simulate a complex listening situation with shifting attention. Directional HA microphones yielded better performance than omnidirectional microphones (both combined with a RM) in near field when analyzing both tasks of the dual-task experiment separately. Furthermore, the integrated dual-task test results showed better performance with directional HA microphones compared with the omnidirectional setting (both cases in combination with a RM). These findings were confirmed by the results of the interleaved speech intelligibility test.

“…In most previous studies on the effect of the Roger Pen, the device was used with the CI only (De Ceulaer et al 2016;Razza et al 2017;Wolfe et al 2015a). Another wireless microphone, the Cochlear Minimic 2þ, was also tested in bimodal CI users.…”

“…By acquiring the signal at or near the source, the signal-tonoise ratio (SNR) at the listener's ear is improved and consequently the negative effects of ambient noise, as well as those of distance and reverberation, are reduced. Previous research has shown considerable improvement in unilateral CI users' speech recognition in noise (De Ceulaer et al 2016;Razza et al 2017;Schafer and Thibodeau 2004;Schafer et al 2009;Vroegop et al 2017;Wolfe et al 2015a;Wolfe, Morais, and Schafer 2015b). A directional mode of the wireless microphone would possibly improve speech recognition even more, but specific, comparative data is lacking.…”

To evaluate whether speech recognition in noise differs according to whether a wireless remote microphone is connected to just the cochlear implant (CI) or to both the CI and to the hearing aid (HA) in bimodal CI users. The second aim was to evaluate the additional benefit of the directional microphone mode compared with the omnidirectional microphone mode of the wireless microphone. This prospective study measured Speech Recognition Thresholds (SRT) in babble noise in a 'within-subjects repeated measures design' for different listening conditions. Eighteen postlingually deafened adult bimodal CI users. No difference in speech recognition in noise in the bimodal listening condition was found between the wireless microphone connected to the CI only and to both the CI and the HA. An improvement of 4.1 dB was found for switching from the omnidirectional microphone mode to the directional mode in the CI only condition. The use of a wireless microphone improved speech recognition in noise for bimodal CI users. The use of the directional microphone mode led to a substantial additional improvement of speech perception in noise for situations with one target signal.
