| Summary: | The advanced camera systems developed for property security prove inadequate when faced with the ease of disabling the cameras. Therefore, incorporating sound data from potential threats can also play a significant role in ensuring property security. This sound event-based approach enables a more compact installation and allows for the use of affordable microphones, offering an alternative to visual-based security systems. We propose deep learning based on a convolutional neural network (CNN) algorithm for classification of footstep sound events. The study includes two consecutive stages: ReaLISED dataset and refined ReaLISED supported by Epidemic Sound data. Sound event files are transformed into Mel-Frequency Cepstral Coefficients (MFCC) and a CNN is fed with the represented images of MFCC. By optimizing the model parameters, our unique model detected footstep sound events with 98% accuracy among 17 other sound events. Validation through Repeated Stratified K-Fold Cross-Validation (5 folds, 10 repetitions) and comparisons with state-of-the-art architectures demonstrated robust performance, with F1-Scores ranging from 0.905 to 0.992 and a mean of 0.960. The strategic incorporation of diverse open-source data fosters transparency and reproducibility, enhancing the model’s adaptability and reliability in handling real-world audio patterns, as evidenced by its commendable 1% error rate in precise identification. |
