Background and Aim: It is well known that hearing aid fitting is an effective approach to improve the communication ability of hearingimpaired people. In the past, most of the hearing aids were fitted unilaterally rather than bilaterally. Whereas the unilateral hearing aid fitting improves verbal communication partially, it causes late-onset auditory deprivation. The main aim of this study is to investigate the ANL for each ear among the users with unilateral hearing aid experience. Methods: A total of 23 participants were recruited (14 females, 9 males). The mean age was 74.65 years (ranged from 41 to 83). All subjects had bilateral symmetric sensorineural hearing loss. The most comfortable level (MCL), Background Noise Level (BNL), and acceptable noise level (ANL) were measured for ear with amplification experience and ear without experience. Results: MCL, BNL and ANL in the aided ear was 82.22, 73.48 and 8.74 respectively, in addition in the unaided ear the results for MCL, BNL and ANL was 81.78, 72.13 and 9.65 respectively. Comparing the mean values of MCL, BNL and ANL between two ears showed no significant difference. Conclusion: There was not any difference for BNL and ANL measures Keywords: Bilateral hearing loss; acceptable noise level; late onset auditory deprivation; Hearing aid

Background and Aim: Noise tolerance and performance in noisy environments are influential factors of hearing aid use in people with hearing loss. One of the causes of hearing loss is Meniere’s disease (MD), which affects speech perception in noise. Acceptable noise level (ANL) is a test that measures the maximum tolerated background noise level (BNL) while listening to the running speech. Since the effect of MD on ANL needs further study, the present study aims to examine the ANL test results in people with unilateral MD, and compare the results between the two ears. Methods: This cross sectional study conducted on 33 individuals with unilateral MD (21 females and 12 males) aged 32–60 years who had the disease for at least one year, who participated in this study. Their most comfortable level (MCL), BNL, and ANL in both ears were then evaluated. Results: The mean MCL and BNL were significantly different between the two ears, where they were higher in the affected ear than in the contralateral ear. There was also a significant difference in the ANL results between the two ears. In the affected ear, a statistically significant relationship was reported between the ANL and the average hearing thresholds at frequencies of 250, 500, and 1000 Hz. Conclusion: MD affects the ANL in the affected ear and causes a deterioration in its level and speech perception in noise.
