  1. 1. Sound Source Distance Estimation Using Sound Frequency Attenuation

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Frida Johnsson; Gillis Oldfeldt; [2023]
    Keywords : Technology and Engineering;

    Abstract : Estimating the distance between a sound source and receiver is an important problem. This thesis explores the possibility of estimating distance from a sound source using the attenuations regarding different frequencies over a distance. This method can be useful in cases where currently existing distance approxima- tion methods are not an option. READ MORE

  3. 2. Automatic loose gravel condition detection using acoustic observations

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Gionian Kyros; Elias Myrén; [2022]
    Keywords : Sound Classification; Supervised Machine Learning; Gravel roads assessment; SVM; Random Forest; Ensemble of bagged trees; Sound feature extraction;

    Abstract : Evaluation of the road's condition and state is essential for its upkeep, especially when discussing gravel roads, for the following reasons, among other. When loose gravel is not adequately maintained, it can pose a hazard to drivers, who can lose control of their vehicle and cause accidents. READ MORE

  4. 3. Speaker Recognition using Biology-Inspired Feature Extraction

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Edvin Andersson; [2021]
    Keywords : Artificial Intelligence; AI; Machine Learning; Speaker Recognition; Technology and Engineering;

    Abstract : Distinguishing between people's voices is something the human brain does naturally, using only frequencies picked up by the inner ear. The field of speaker recognition is concerned with making machines do the same thing using digitally sampled speech and data processing. READ MORE

  5. 4. Detection of Deviations in Beehives Based on Sound Analysis and Machine Learning

    University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Author : Amer Hodzic; Danny Hoang; [2021]
    Keywords : unsupervised machine learning; clustering; DBSCAN; honeybees; beehives; sound analysis;

    Abstract : Honeybees are an essential part of our ecosystem as they take care of most of the pollination in the world. They also produce honey, which is the main reason beekeeping was introduced in the first place. READ MORE

  6. 5. Categorisation of the Emotional Tone of Music using Neural Networks

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jacob Hedén Malm; Kyle Sinclair; [2020]
    Keywords : Artificial Neural Network; Emotion; Music; Audio Processing; Music Categorisation; Artificiellt Neuronnät; Känslor; Musik; Ljudprocessering; Musik Kategorisering;

    Abstract : Machine categorisation of the emotional content of music is an ongoing research area. Feature description and extraction for such a vague and subjective field as emotion presents a difficulty for human-designed audioprocessing. READ MORE
