As AI-powered acoustic sensing technologies proliferate across ecological and urban environments, machine listening systems are increasingly tasked with interpreting, classifying, and acting upon soundscapes once mediated through human perception. This paper explores the ethical and socio-technical dimensions of AI-driven soundscape monitoring and analytics, positioning it within the broader field of human auditory ecology. We argue that while such systems promise unprecedented ecological insight—detecting biodiversity shifts, illegal activity, and environmental change—they also pose significant risks of privacy intrusion, algorithmic bias, and acoustic surveillance. Bridging computational bioacoustics, auditory neuro-science, and critical data ethics, the paper examines how machine listening reconfigures the sensory and political dynamics of listening. Drawing on interdisciplinary scholarship, we develop a normative framework for ethical soundscape AI, foregrounding principles of acoustic privacy, data minimization, participatory governance, and environmental justice. We also propose a technical architecture that integrates edge computing, differential privacy, federated learning, and homomorphic encryption to operationalize these commitments. By interrogating who gets to listen, what is heard, and whose voices are silenced or amplified, this paper calls for a reimagining of sound-scape AI—not as a tool of extractive surveillance, but as a relational, accountable, and pluralistic infrastructure. In doing so, we contribute to advancing human auditory ecology in the age of algorithmic listening.
