The benefit of using smartphones for hearing tests in a non-supervised, rapid, and contactless way has drawn a lot of interest, especially if supra-threshold measures are assessed that go beyond audiogram-based measures alone. It is unclear, nevertheless, how well these measures compare to more supervised and regulated manual audiometric assessments. The aim of this study is to validate such smartphone-based methods against standardised laboratory assessments.
Pure-tone audiometry and categorical loudness scaling (CLS) were used. Three conditions with varying degrees of supervision were created and compared. In order to assess binaural and spectral loudness summation, both narrowband monaural and broadband binaural noise have been examined as CLS test stimuli.
= 21 individuals with normal hearing and = 16 participants with mild-to-moderate hearing loss.
The tests conducted here did not show any distinctions between smartphone-based and laboratory-based methods.
Non-supervised listening tests via smartphone may serve as a valid, reliable, and cost-effective approach, e.g. for pure-tone audiometry, CLS, and the evaluation of binaural and spectral loudness summation. In addition, the supra-threshold tests can be constructed to be invariant against missing calibration and external noise which makes them more robust for smartphone usage than audiogram measures.
以非监督、快速且非接触的方式使用智能手机进行听力测试的益处引发了诸多关注，特别是在评估超越单纯基于听力图的超阈值测量时。然而，尚不清楚这些测量与更具监督和规范的手动听力评估相比效果如何。本研究的目的是针对标准化实验室评估验证此类基于智能手机的方法。
采用纯音听力测定法和分类响度标度法（CLS）。创建并比较了三种不同监督程度的条件。为了评估双耳和频谱响度总和，已将窄带单耳和宽带双耳噪声作为CLS测试刺激进行了检查。
21名听力正常的个体和16名轻度至中度听力损失的参与者。
此处进行的测试未显示基于智能手机的方法与基于实验室的方法之间存在任何差异。
通过智能手机进行的非监督听力测试可作为一种有效、可靠且具有成本效益的方法，例如用于纯音听力测定、CLS以及双耳和频谱响度总和的评估。此外，超阈值测试可以构建为对缺失校准和外部噪声具有不变性，这使得它们在智能手机使用中比听力图测量更具鲁棒性。
