“…Our data are in agreement with previous studies demonstrating the successful application of ADMT in adults with bilaterally and unilaterally hearing impairment who use hearing aid(s) and CI (s). 21,22,[28][29][30][31] Furthermore, we have been able to expand previous findings demonstrating the benefit of frequency modulation technology and ADMT in bilaterally hearingimpaired children 19,[32][33][34] to children with SSD. The extension to children with SSD who use a CI has a direct clinical impact, as remote wireless technology can and should be considered for children with SSD who use a CI.…”

“…21 In a later examination, Wesarg et al 22 revealed better speech recognition with the application of ADMT at the NH ear or bilaterally than at the CI alone in adults with SSD show use a CI. The different benefits of alternating ADMT application might be attributable to different speech recognition with the CI between the populations included in the two studies of Wesarg et al 21,22 Speech recognition with the CI (no ADMT) was superior on average in the cohort of the previous study than in the following study. 21,22 In the present investigation, only a trend was seen for the correlation between speech recognition in NH þ CI/A for a frontal speaker and word recognition at 65 dB SPL with the CI alone.…”

“…20 The advantage of the unilateral (CI or NH ear) or bilateral application of ADMT was also shown in adults with SSD who use a CI. 21,22 The objective of the present study was to determine whether the application of ADMT improves speech recognition in multisource background noise in children with SSD who use a CI. It is examined if ADMTon the CI or on the NH ear improves speech recognition in noise for a distant, frontal speaker and lateral, close speakers.…”

“…25 Whereas children mainly use slowly changing dynamic and temporal stimuli, adults rely mainly on static spectral cues. 25 Differences between hearing abilities in adults and children do not permit the direct transfer of results obtained from adults with SSD who use CI with ADMT 21,22 to the pediatric popula-tion. The investigation of ADMT application explicitly in children with SSD is therefore required.…”

Background Previous research demonstrated benefits of adaptive digital microphone technologies (ADMTs) in adults with single-sided deafness (SSD) having a cochlear implant (CI). Children with SSD are especially affected by background noise because of their noise exposure in kindergarten and school. Purpose This article aims to evaluate possible effects of ADMT on speech recognition in background noise in children with SSD who use a CI. Study Sample Ten children between 5 and 11 years of age were included. Data Collection and Analysis Speech recognition in noise was assessed for one frontal distant and two lateral speakers. The speech stimulus was presented at a speech level of 65 dB(A) and noise at a level of 55 dB(A). For the presentation condition with one frontal speaker, four listening conditions were assessed: (1) normal-hearing (NH) ear and CI turned off; (2) NH ear and CI; (3) NH ear and CI with ADMT; and (4) NH ear with ADMT and CI. Listening conditions (2) to (4) were also tested for each lateral speaker. The frontal speaker was positioned directly in front of the participant, whereas the lateral speakers were positioned at angles of 90 degrees and –90 degrees to the participant's head. Results Children with SSD who use a CI significantly benefit from the application of ADMT in speech recognition in noise for frontal distant and for lateral speakers. Speech recognition improved significantly with ADMT at the CI and the NH ears. Conclusion Application of ADMT significantly improves speech recognition in noise in children with SSD who use a CI and can therefore be highly recommended. The decision of whether to apply ADMT at the CI NH ear or bilaterally should be made for each child individually.

Thanks to the maturity and innovation of embedded technology, products based on embedded platforms continue to penetrate people’s lives and play a pivotal role in various fields of society, while the development of data acquisition systems based on wireless communication of embedded microprocessors is one of the frontier directions of embedded development. Modern commercial bank risk management system includes risk control organization, risk measurement techniques (including risk warning), risk avoidance techniques, and total risk management model. In this paper, a multichannel data acquisition system combined with a wireless sensor platform is designed for early warning of default risk of Internet financial bank customers, which can realize real-time monitoring, acquisition, display, and data storage of DC signals and indoor environment information output from sensor platforms or electronic devices, and for frequent transactions, fund splitting, and mortgage pledging related to complex customers in today’s e-commerce platform, which triggers when the associated enterprise credit risk presents complexity, continuity, wholeness, multiplicity, volatility, severity, etc., it is used to improve risk judgment and risk warning ability, enhance investment risk response ability, and reduce the related losses caused by marketing risk.

Signal Transparency of Remote Microphone Technology in Pediatric Bone Conduction Device Users

2023

Introduction: Competing noise in the environment negatively affects speech intelligibility, particularly when listening at a distance. This is especially true for children with hearing loss in classroom environments where the signal-to-noise ratio is often poor. Remote microphone technology has been shown to be highly beneficial at improving the signal-to-noise ratio in hearing device users. Children with bone conduction devices, however, often must rely on indirect transmission of the acoustic signal for commonly used classroom-based remote microphone listening (e.g., digital adaptive microphone) which may negatively affect speech intelligibility. There are no studies on the effectiveness of using a relay method of signal delivery using remote microphone technology to improve speech intelligibility in adverse listening environments in bone conduction device users. Methods: Nine children with irresolvable conductive hearing loss and 12 adult controls with normal hearing were included for study. Controls were bilaterally plugged to simulate conductive hearing loss. All testing was conducted using the Cochlear™ Baha® 5 standard processor coupled with either the Cochlear™ Mini Microphone 2+ digital remote microphone or the Phonak Roger™ adaptive digital remote microphone. Speech intelligibility in noise was evaluated in the (1) bone conduction device processor alone, (2) bone conduction device + personal remote microphone, and (3) bone conduction device + personal remote microphone + adaptive digital remote microphone listening conditions at −10 dB, 0 dB, and +5 dB signal-to-noise ratios. Results and Conclusions: Speech intelligibility in noise improved significantly in the bone conduction device + personal remote microphone condition over the bone conduction device alone, demonstrating significant benefit for listening at poor signal-to-noise ratios in children with conductive hearing loss using bone conduction devices with personal remote microphone use. Experimental findings demonstrate poor signal transparency when using the relay method. Coupling of the adaptive digital remote microphone technology to the personal remote microphone negatively affects signal transparency, and no hearing in noise improvements are observed. Significant gains in speech intelligibility are consistently observed for direct streaming methods and are confirmed in adult controls. Behavioral findings are supported by objective verification of the signal transparency between the remote microphone and the bone conduction device.
