    Attention-Based CRNN Models for Identification of Respiratory Diseases from Lung Sounds
    (Institute of Electrical and Electronics Engineers Inc., 2023) Sanjana, J.; Naik, P.P.; Mahesh, M.A.; Koolagudi, S.G.; Rajan, J.
    Respiratory diseases are a major global health concern, with millions of people suffering from disorders such as asthma, bronchitis, chronic obstructive pulmonary disease (COPD), and pneumonia. In recent years, machine learning and other forms of Artificial Intelligence have proven to be useful resources for resolving issues in the medical field. In this study, we examine the diagnostic utility of Convolutional Recurrent Neural Network (CRNN) models for identifying respiratory diseases using digitally recorded lung sounds. We developed two deep learning models to diagnose and classify lung diseases: a binary classification to classify COPD and non-COPD, and a multi-class classification model to classify five lung disorders (COPD, URTI-upper respiratory tract infection, Pneumonia, Bronchiectasis and Bronchiolitis) and healthy conditions. The ICBHI 2017 challenge dataset [1] was used to develop the models. The accuracy of the binary and multiclass classification models was 98.6% and 97.6%, respectively, with ICBHI Scores of 0.9866 and 0.9723. © 2023 IEEE.

    Designing a Bioacoustics Gun for the Prevention of Bird Attacks in Farms, Fields & Buildings
    (Institute of Electrical and Electronics Engineers Inc., 2025) Sanjana, J.; Narasimhan, V.L.
    This paper presents the design and application of a bioacoustics gun aimed at preventing bird attacks in agricultural, horticultural fields, airports, and tall buildings. Bioacoustics, a field of study focusing on animal communication through sound, forms the basis of this innovative approach. A bioacoustics gun emits specific sound signals like ultrasonic signals or acoustic waves that deter birds from targeted areas. This paper describes an experiment first conducted by using a single speaker and also through an array of speakers. By employing array speakers arranged in a specific geometric configuration and providing appropriate phase delays to each speaker, the bioacoustics gun achieves precise control over sound direction and distribution, thereby enhancing its effectiveness. This humane and eco-friendly approach to bird management offers promising solutions for mitigating bird-related issues while promoting sustainable practices across various sectors. Performance metrics of the bioacoustics gun is also provided in this paper. © 2025 IEEE.
