摘要
Abstract
Objective To analyze cortisol levels in saliva in bilateral cochlear implant recipients under three distinct conditions,providing novel methodological evidence for the assessment of auditory fatigue and cognitive load.Methods This study included 15 bilateral cochlear implant recipients(6 females and 9 males,aged 3.8～47.3 years[mean=10.83±10.49 years])who underwent programming in May 2025.Saliva samples were collected after 2:00 PM to eliminate the influence of circadian rhythm cortisol secretion.Samples were collected under three conditions:baseline state(no task),bilateral cochlear implants use in noise,and unilateral cochlear implant use in noise.The auditory task was performed in a noise environment with a signal-to-noise ratio of-15 dB HL for 15 minutes.Results Paired t-tests revealed no significant difference in cortisol levels between the bilateral auditory task and the baseline state(P=0.488).However,cortisol levels were significantly higher after the unilateral auditory task compared to both the bilateral task(P=0.017)and the baseline state(P=0.048).Conclusions Unilateral cochlear implant use in noisy environments may induce a pronounced physiological stress responses,suggesting that the impact of auditory load on patients'physiological and psychological state should be a key consideration in clinical rehabilitation programs.关键词
