Article Abstract
Objective: Assess the influence of cochlear implant (CI) use on the perceived listening effort of adult and pediatric subjects with unilateral hearing loss (UHL) or asymmetric hearing loss (AHL).
Study Design: Prospective cohort.
Setting: Tertiary referral center.
Patients: Adults and children with UHL or AHL.
Intervention: Cochlear implantation. Subjects received their CI as part of a clinical trial assessing the effectiveness of cochlear implantation in cases of UHL and AHL.
Main Outcome Measures: Responses to the Listening Effort pragmatic subscale on the Speech, Spatial, and Qualities of Hearing Scale (SSQ) or SSQ for Children with Impaired Hearing (SSQ-C) were compared over the study period. Subjects or their parents completed the questionnaires preoperatively and at predetermined postactivation intervals. For the adult subjects, responses were compared to word recognition in quiet and sentence recognition in noise.
Results: Forty adult subjects (n = 20 UHL, n = 20 AHL) and 16 pediatric subjects with UHL enrolled and underwent cochlear implantation. Subjects in all three groups reported a significant reduction in perceived listening effort within the initial months of CI use (p < 0.001; η2 ≥ 0.351). The perceived benefit was significantly correlated with speech recognition in noise for the adult subjects with UHL at the 12-month interval (r(20) = .59, p = 0.006).
Conclusions: Adult and pediatric CI recipients with UHL or AHL report a reduction in listening effort with CI use as compared to their preoperative experiences. Use of the SSQ and SSQ-C Listening Effort pragmatic subscale may provide additional information about a CI recipient's experience beyond the abilities measured in the sound booth.

Background And Objective: Speech comprehension in a foreign language under noise conditions presents an increased cognitive demand. For multilingual patients with cochlear implants (PwCI), this poses a particular challenge, as audiological routine diagnostics are typically conducted in the language of the clinical environment. This study investigates speech understanding in noise as well as the subjectively perceived listening effort in PwCI compared to normal-hearing (NH) individuals under both native and nonnative language conditions.

While blink analysis was traditionally conducted within vision research, recent studies suggest that blinks might reflect a more general cognitive strategy for resource allocation, including with auditory tasks, but its use within the fields of Audiology or Psychoacoustics remains scarce and its interpretation largely speculative. It is hypothesized that as listening conditions become more difficult, the number of blinks would decrease, especially during stimulus presentation, because it reflects a window of alertness. In experiment 1, 21 participants were presented with 80 sentences at different signal-to-noise ratios (SNRs): 0, + 7, + 14 dB and in quiet, in a sound-proof room with gaze and luminance controlled (75 lux).

Understanding speech in noise is a common challenge for older adults, often requiring increased listening effort that can deplete cognitive resources and impair higher-order functions. Hearing aids are the gold standard intervention for hearing loss, but cost and accessibility barriers have driven interest in alternatives such as Personal Sound Amplification Products (PSAPs). While PSAPs are not medical devices, they may help reduce listening effort in certain contexts, though supporting evidence remains limited.

Understanding speech in noise depends on several interacting factors, including the signal-to-noise ratio (SNR), speech intelligibility (SI), and attentional engagement. However, how these factors relate to selective neural speech tracking remains unclear. In this study, we recorded EEG and eye-tracking data while participants performed a selective listening task involving a target talker in the presence of a competing masker talker and background noise across a wide range of SNRs.

In this study, we used functional near-infrared spectroscopy to examine the neurophysiological effects of active noise cancellation (ANC) technology on cognitive performance in noisy environments. Forty-one normal-hearing adults performed an auditory decision-making task in ANC ON and ANC OFF conditions. During the task, concentration changes in oxyhemoglobin (Δoxy-Hb) in the prefrontal cortex were measured, subjective listening effort was assessed using a visual analog scale (VAS), and behavioral performance measures (accuracy and reaction time) were collected.
