UrbanSound8K-C (US8-C) serves as a benchmark for DHAuDS in the context of test-time adaptation for audio classification. US8-C, a subset of UrbanSound8K, utilizes only test-set samples to address domain shift. Each sample in US8-C has a duration of 4 seconds, a sample rate of 44.1 kHz, and belongs to one of 10 classes. The dataset comprises two sets: adaptation and evaluation sets. Each set comprises four corruption categories and two levels. Four corruption categories are defined: WHN, ENSC, TST, and PSH. Two levels are defined: L1 and L2, where L2 indicates a higher degree of complexity. As for evaluation and adaptation sets, each comprises 9,836 samples. In total, US8-C consists of 19,672 samples, with each category-level, such as WHN-L1 or WHN-L2, containing 2,459 samples.
