Acoustic Camera for Sound Source Localization
For Preventive Maintenance
Acoustic imaging cameras are one of the most exciting technological developments in preventive maintenance. Using beamforming, the devices precisely locate sound sources and visualize signals from the audible and ultrasonic range in real time in the form of acoustic images and videos. This combination of sound sensors and digital imaging enables maintenance technicians to quickly and intuitively identify defective areas such as leaks in compressed air systems or partial discharges in electrical systems.

FAQ
Acoustic imaging is a technique that transforms sound signals into visual images. Put simply, it lets you see sound.
Defects such as gas leaks or partial discharges often generate ultrasonic sounds that are inaudible to humans. Acoustic imagers are equipped with a large number of microphones to detect and precisely localize these signals. The acoustic image of the sound source generated by the microphones is combined with a camera image of the visible surroundings, for example within an industrial plant. By visualizing the recorded sound signals, acoustic cameras make defects in compressed air systems or electrical systems visible, turning them into valuable tools for preventive maintenance.
An acoustic image or video provides a visual representation of sound. Typically, the acoustic image is layered on a visual image for context, allowing you to see the location and intensity or loudness of sound sources within the field of view in real-time. Besides, the acoustic camera provides information about the frequency components of the sound, helping to distinguish between different types of noise or sound emissions.
An acoustic camera uses a microphone array consisting of many individually arranged microphones. This allows the camera to capture sound waves from different directions. Using beamforming, the acoustic camera can control the directional characteristic of the microphone array. This means that the camera is able to focus sound from a certain direction and suppress sound from other directions. The beamforming technology therefore enables the camera to display the exact position of sound sources on a visual map - the acoustic image. This is done by analyzing the differences in the time of flight of the sound waves between the microphones. The acoustic image then shows where the sound is coming from and how intense it is.
Use of Acoustic Imaging Cameras in Preventive Maintenance
In industry, preventive maintenance is key for trouble-free and efficient operations. Our SONASCREEN® acoustic imaging cameras are cutting-edge tools that can revolutionize this process. By visualizing sound emissions, these devices help to detect potential problems at an early stage and thus avoid costly downtime and equipment failures.
One of the main advantages of using acoustic imagers in preventive maintenance is the early detection of problems. The SONASCREEN acoustic cameras enable the early detection of anomalies such as leaks in compressed air, gas or vacuum systems and electrical discharges. This early detection is crucial for eliminating problems before they develop into major failures or safety hazards. Detecting issues like gas leaks or electrical faults early reduces the risk of incidents, protecting both the workforce and the facility.
In addition, acoustic cameras offer a non-invasive way to monitor equipment and provide real-time images that allow maintenance teams to diagnose issues immediately without interrupting operations. Designed for ease of use and portability, our SONASCREEN acoustic cameras allow for quick and efficient inspections and come with intuitive software that enhances data analysis and reporting.
Implementing acoustic imaging cameras into preventive maintenance strategies improves reliability and operation efficiency. The SONASCREEN acoustic imagers provide a clear and immediate picture of system condition, helping maintenance professionals make informed decisions, reduce downtime and ultimately save costs.
