Abstract
Summary One of the most frequent complaints of adult hearing aid users is that comprehending speech is challenging in noisy environments. Indeed, insufficient benefit of hearing aids in noisy situations seems to be an important reason for people fitted with a hearing aid not to use it (Koch et al., 2016). Nabelek and colleagues (1991), developed the acceptable noise level (ANL) test to quantify a person’s background noise tolerance. The ANL was defined as the difference between the most comfortable level when following discourse, and the maximal amount of background noise that can be tolerated while still following the discourse (Walravens et al., 2014). ANL was classified into three categories: low ANL (< 7dB), mid (from 7.1 to 13 dB) and high ANL (>13 dB) and a logistic regression analysis demonstrated that unaided ANL can predict success rate with hearing aid (Nabelek et al., 2006). Mahmoud et al., (2018) developed the Arabic speech material for testing ANL and to standardize the test in normal hearing Egyptian adults and also to study the effect of hearing loss on ANL. The APHAB also has been used to predict hearing aid use and for evaluating relationships between acceptable noise levels and subjective outcome measures for hearing aid and cochlear implant users (Johnson et al., 2010). Our work was designed to study the acceptable noise level (ANL) in patients with moderate to moderately severe sensorineural hearing loss & Study the effect of hearing aid use on ANL & the relation between self
