Smart Building Acoustic Sensor Market Report 2025

The smart building acoustic sensor market size has grown rapidly in recent years. It will grow from $1.37 billion in 2024 to $1.6 billion in 2025 at a compound annual growth rate (CAGR) of 16.8%. The growth during the historic period can be attributed to increasing demand for wireless and energy-efficient devices, strong interest in surface acoustic wave (SAW)-based temperature sensors, heightened environmental concerns driving advanced monitoring solutions, expanding integration of artificial intelligence (AI) in acoustic wave sensor technology, and rising use of advanced sensing technologies for vibration detection.

The smart building acoustic sensor market size is expected to see rapid growth in the next few years. It will grow to $2.94 billion in 2029 at a compound annual growth rate (CAGR) of 16.5%. The expected growth in the forecast period can be linked to the expansion of smart city initiatives, rising adoption of AI-powered acoustic sensors, growing concerns over noise pollution, increased regulatory pressure from governments to control noise levels, and a surging demand for real-time infrastructure monitoring. Key trends anticipated during this period include integration with AI-based anomaly detection systems, the adoption of cloud-based platforms for acoustic analytics, development of self-calibrating sensor technologies, use of acoustic sensing for touchless occupant interaction, and incorporation of blockchain-enabled solutions into building management systems.

The growth of smart cities is significantly driving the expansion of the smart building acoustic sensor market, fueled by increasing urbanization and investments in digital infrastructure aimed at enhancing urban efficiency and livability. As more people move into urban areas, the demand for intelligent infrastructure, such as noise monitoring and environmental quality systems, rises. Acoustic sensors play a crucial role in these smart city environments by enabling real-time sound level monitoring, supporting healthier and safer urban living. For example, according to the International Institute for Management Development, the number of smart cities globally grew from 118 in 2021 to 141 in 2023, illustrating the accelerating trend that is boosting demand for smart acoustic technologies.

Major players in the smart building acoustic sensor market are advancing ultra-low-power sensor technologies to enhance energy efficiency and ensure seamless integration with smart building automation systems. These sensor systems are designed to operate with minimal energy consumption while continuously monitoring sound levels, thereby extending device lifespan, reducing operational costs, and supporting sustainable smart infrastructure. For example, in June 2022, Infineon Technologies, a Germany-based semiconductor company, introduced its battery-powered Smart Alarm System (SAS), which features AI and machine learning-based acoustic event detection combined with sensor fusion. The system integrates a high signal-to-noise ratio MEMS microphone, a digital pressure sensor, and a PSoC microcontroller to deliver accurate detection with low power usage. Its advanced AI/ML algorithms enable precise differentiation between relevant sounds and background noise, minimizing false alarms. This compact and energy-efficient solution is ideal for smart buildings, homes, and IoT environments.

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.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The rapid escalation of U.S. tariffs and the resulting trade tensions in spring 2025 are significantly impacting the construction sector, particularly in materials procurement and project costs. Higher duties on imported steel, aluminum, lumber, and machinery have driven up expenses for builders, contractors, and infrastructure developers, leading to increased project bids and delayed timelines. Construction equipment manufacturers face similar challenges, with tariffs on essential components and raw materials inflating production costs and squeezing margins. Additionally, retaliatory tariffs in international markets have curtailed exports of U.S.-made construction equipment and materials, further affecting profitability. The sector must now prioritize local sourcing, modular construction techniques, and supply chain diversification to control costs and ensure project viability amid ongoing trade uncertainties.

A smart building acoustic sensor is a sophisticated device designed to monitor and analyze sounds within buildings to enable intelligent operations. It detects acoustic signals and utilizes AI or machine learning to distinguish between background noise, human activity, and unusual occurrences. By providing real-time data, the sensor enhances building automation systems, boosting safety, operational efficiency, and the overall experience of occupants.

The primary types of smart building acoustic sensors include wired and wireless variants. Wired acoustic sensors connect via physical cables to monitor and assess sound levels in buildings for diverse applications. These sensors are distributed through multiple channels, such as direct sales, distributors or wholesalers, and online retail. They serve various applications such as noise monitoring, security and surveillance, HVAC system monitoring, occupancy detection, and more. End-users encompass commercial and residential buildings, industrial facilities, educational institutions, healthcare centers, and others.
