  1. 1. Compare Accuracy of Alternative Methods for Sound Classification on Environmental Sounds of Similar Characteristics

    University essay from Stockholms universitet/Statistiska institutionen

    Author : Olov Rudberg; [2022]
    Keywords : Machine Learning; Algorithms; Neural Networks; Computer Vision; Image Recognition; Environmental Sound Classification; Data Augmentation;

    Abstract : Artificial neural networks have in the last decade been a vital tool in image recognition, signal processing and speech recognition. Because of these networks' ability to be highly flexible, they suit a vast amount of different data. This flexible attribute is very sought for within the field of environmental sound classification.

    Abstract : Noise is defined as any undesired sound. Urban noise and its effect on citizens area significant environmental problem, and the increasing level of noise has become a critical problem in some cities. Fortunately, noise pollution can be mitigated by better planning of urban areas or controlled by administrative regulations. READ MORE

  5. 4. Audio representation for environmental sound classification using convolutional neural networks

    University essay from Lunds universitet/Matematik LTH

    Author : Linus Lexfors; Malte Johansson; [2018]
    Keywords : Sound classification; machine learning; cnn; Mathematics and Statistics;

    Abstract : A convolutional neural network (CNN) training framework is described and implemented. The framework is used to train and evaluate an audio classification system, focused on evaluating differences in audio representation. The dataset used is ESC-50, containing 50 different classes of audio. READ MORE
