The rise of smart cities is expected to drive the growth of the smart building acoustic sensor market in the coming years. A smart city is an urban environment that uses various electronic systems and sensors to collect data and efficiently manage assets, resources, and public services. The growth of smart cities is fueled by increasing global urbanization and expanded government investment in digital infrastructure aimed at improving quality of life and operational efficiency. As smart cities continue developing, demand for intelligent infrastructure solutions grows, driven by the fact that more than half of the world’s population now resides in urban areas. This expansion increases the need for acoustic sensors, which play a critical role in noise monitoring, environmental quality evaluation, and supporting healthier living spaces through real-time sound level management. For example, in April 2025, the International Institute for Management Development (IMD), a Switzerland-based business school, reported that the Smart City Index 2025 included assessments of 146 cities, reflecting a broader global scope. Therefore, the rise of smart cities is contributing to the growth of the smart building acoustic sensor market.

Major players in the smart building acoustic sensor market are prioritizing the development of advanced technologies, such as wireless sensor systems, to support seamless integration with building management platforms, improve energy efficiency, and enable real-time acoustic event monitoring. Wireless sensor systems are networks of connected sensors that transmit information using wireless communication technologies, eliminating the requirement for physical wiring for power or data transmission. For example, in February 2025, PassiveLogic, a US-based autonomous building infrastructure provider, introduced the Sense Nano. It generates its own energy from the surrounding environment, requiring neither batteries nor wiring. Its fully wireless design supports flexible installation within buildings, featuring a compact size (under 2 inches in diameter) and an architecturally refined enclosure (CNC-machined aircraft-grade aluminum). The system offers fast setup through a companion mobile application (Quantum Lens), which automatically identifies the sensor’s installed location and simplifies integration into a building’s digital twin.

In December 2023, Motorola Solutions, a US-based technology company specializing in safety and security solutions, acquired IPVideo Corporation for an undisclosed amount to strengthen its presence in the smart building acoustic security market. This acquisition expands Motorola’s physical-security ecosystem by integrating IPVideo’s HALO IoT Smart Sensor, a non-video threat-detection device that uses acoustic sensing and environmental monitoring. The HALO sensor is particularly valuable in privacy-sensitive areas such as restrooms, hospital rooms, classrooms, and hotel rooms, where traditional video surveillance cannot be deployed. By leveraging this technology, Motorola Solutions aims to extend situational awareness and enhance safety through discreet, sensor-based monitoring.
