“…Access to critical speech information is negatively affected, even at small distances typical of classroom environments [Leavitt and Flexer, 1991], and compounded by the presence of competing noise. Further, previous studies have demonstrated that listening abilities are compromised in classroom environments even in mild and unilateral HL [Hawkins, 1984;Ruscetta et al, 2005;Noh and Park, 2012] and aided listening [Hawkins, 1984;Smaldino and Crandell, 2000;Lewis et al, 2004;Mondelli et al, 2019;Snapp et al, 2020].…”

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.

“…There are no known studies to date that have investigated the combination of CROS and RM devices (e.g., Cochlear Baha + MiniMic 2+) for children with severe-to-profound unilateral sensorineural hearing loss. Snapp et al (2020) assessed speech-in-noise performance in 10 children with unilateral conductive hearing loss fitted with a BC CROS. Subjects listened in the unaided, BC CROS, and BC CROS + RM conditions.…”

Objectives: Limited evidence exists for the use of rerouting devices in children with severe-to-profound unilateral sensorineural hearing loss. Many laboratory studies to date have evaluated hearing-in-noise performance in specific target-masker spatial configurations within a small group of participants and with only a subset of available hearing devices. In the present study, the efficacy of all major types of nonsurgical devices was evaluated within a larger group of pediatric subjects on a challenging speech-in-noise recognition task.Design: Children (7-18 years) with unaided severe-to-profound unilateral hearing loss (UHL‚ n = 36) or bilateral normal hearing (NH, n = 36) participated in the present study. The signal-to-noise ratio (SNR) required for 50% speech understanding (SNR-50) was measured using BKB sentences in the presence of proprietary restaurant noise (R-SPACE BSIN-R) in the R-SPACE Sound System. Subjects listened under 2 target/masker spatial configurations. The target signal was directed toward subjects' NH or hearing-impaired ear (45º azimuth), while the interfering restaurant noise masker was presented from the remaining 7 loudspeakers encircling the subject, spaced every 45º. Head position was fixed during testing. The presentation level of target sentences and masking noise varied over time to estimate the SNR-50 (dB). The following devices were tested in all participants with severe-to-profound UHL: air conduction (AC) contralateral routing of signal (CROS), bone conduction (BC) CROS fitted on a headband with and without the use of remote microphone (RM), and an ear-level RM hearing assistance technology (HAT) system.Results: As a group, participants with severe-to-profound UHL performed best when the target signal was directed toward their NH ear. Across listening conditions, there was an average 8.5 dB improvement in SNR-50 by simply orienting the NH ear toward the target signal. When unaided, participants with severe-to-profound UHL performed as well as participants with NH when the target signal was directed toward the NH ear. Performance was negatively affected by AC CROS when the target signal was directed toward the NH ear, whereas no statistically significant change in performance was observed when using BC CROS. When the target signal was directed toward participants' hearing-impaired ear, all tested devices improved SNR-50 compared with the unaided condition, with small improvements (1-2 dB) observed with CROS devices and the largest improvement (9 dB) gained with the personal ear-level RM HAT system. No added benefit nor decrement was observed when RM was added to BC CROS using a 50/50 mixing ratio when the target was directed toward the impaired ear. Conclusions:In a challenging listening environment with diffuse restaurant noise, SNR-50 was most improved in the study sample when using a personal ear-level RM HAT system. Although tested rerouting devices offered measurable improvement in performance (1-2 dB in SNR-50) when the target was directed to the impaired ear, benefit may...

Objectives: Social determinants of health (SDOH) (healthcare access and quality, education access and quality, socioeconomic status, social and cultural context, neighborhood and built environment) (Healthy People 2030) have been shown to impact a wide range of health-related outcomes and access to care. Given the medical and nonmedical costs associated with children with unilateral hearing loss (UHL), the varied insurance coverage for hearing healthcare services, and the differences in hearing aid utilization rates between children of different sociodemographic classes, the sociodemographic information of children with UHL enrolled in research studies should be collected to ensure the generalizability of hearing healthcare interventions. Therefore, the objective of this scoping review is to assess the reporting of SDOH data for participants in studies of pediatric UHL and its comparison to population trends. Design: Two searches of published literature were conducted by a qualified medical librarian. Two reviewers then evaluated all candidate articles. Study inclusion parameters were from 2010 to present, peer-reviewed studies with prospective study design, and participant population including children (age 0 to 18 years old) with UHL. Results: Two literature searches using PubMed Medline and Embase found 442 and 3058 studies each for review. After abstract and paper review, 87 studies were included in final qualitative review, with 22 of these studies reporting race distribution of participants, 15 reporting insurance status or family income, and 12 reporting the maternal education level. Conclusions: Sociodemographic data are not commonly reported in research studies of children with UHL. In reported samples, research participants are more likely to have private insurance and higher family income compared with overall population distribution. These demographic biases may affect the generalizability of study results to all children with UHL. Further evaluation is warranted to evaluate whether participant recruitment affects outcomes that reflect the overall population.
