Table 2 Automatic detection results for different related and the proposed method

Method	Detection rate (%)	False-positive rate (%)
Hao et al. [44]	78.6	78.6
Venter and Hanekom [28]	85.7*	14.2*
Proposed method without signal enhancement	88.2	24.4
Proposed method with signal enhancement	88.2	13.7

Signal enhancement strongly influences detection performance, especially the false-positive rate
* Results by Venter and Hanekom [28] are not directly comparable as they were obtained for a different (smaller) dataset with fewer rumbles
