These disturbances interfere with essential biological processes, including communication, behavior, and physiological functions. Amidst the sparse literature on direct assessments, metabolomics emerges as a pioneering technique, offering an innovative lens to scrutinize underwater noise's subtle yet profound effects. By analyzing low-molecular-weightmetabolites, metabolomics provides unparalleled insights into the physiological state changes in marine organisms, unveiling the alterations in metabolic pathways triggered by noise exposure. This perspective article underscores the imperative role of metabolomics in bridging the gap inunderstanding how underwater noise constitutes an environmental stressor. It delves into the potential of advanced analytical methods to dissect the complexities of marine life responses, thereby paving the way for devising effective strategies to mitigate the impacts of underwater noise. Through this discussion, we aim to catalyze further research in this nascent field, highlighting the critical need for comprehensive studies that employ metabolomics to explore the broader ecological ramifications of underwater noise on marine biodiversity.Keywords: Metabolomics, underwater noise, marine, physiology.* Corresponding author, E-mail: hinkiu.mok@gmail.com Received 15 January 2024, Accepted 7 May 2024.
