“…Acoustic camera itself represents just one stage in long history of microphone array technology development [14]. Possible applications of acoustic camera as test equipment include nondestructive measurements for noise/sound of road vehicles [15], trains and airplanes [16], [17], quantification of industrial noise [18], measurement of wind turbines [18], acoustical sensing in battlefield [20], obtaining acoustic images of seafloor hydrothermal flaws [21], underwater unmanned vehicles [20] and even observation of marine fauna [23].…”

-This paper focuses on the aspect of performing acoustic analysis for the purpose of electric motors diagnostics. The measurements are performed in noisy industrial environment with the use of a dedicated acoustic camera build by ABB. The acoustic camera comprises a set of microphones arranged in a pre-defined, carefully designed and manufactured shape. The great advantage of acoustic cameras is the sound measurements can be used to pin-point the exact location of the sound source in a monitored scene. This, in turn allows for the frequencies of interest to be separated from the background noise. The paper presents the result of comparing the acoustic camera outputs from two induction motor -a healthy motor and a motor suffering from a broken rotor bar fault. The presented results show that the acoustic camera is capable of detecting the characteristic electric motor fault and robustly localize it in space, which proves its robustness even in noisy industrial environment.

“…Acoustic camera is currently used for many different application for example: localization of sound of road vehicles [13], trains and airplanes [14], [15], quantification of industrial noise [16], measurement of wind turbines [17]. Some works presents results of using acoustic camera in underwater applications for example: obtaining acoustic images of seafloor hydrothermal flaws [19], [19], observation of marine fauna [21] or underwater unmanned vehicles [18].…”

The work described in this paper focuses on the design of a low cost, hand held acoustic camera. The novel process of creating the camera has been entirely engineered in ABB Ltd.Even though the creation of the acoustic camera with the use of 3D printing techniq ues may come at the cost of slightly decreased accuracy of the measurements, when compared with the commercially available solutions, however this is entirely acceptable in many applications. Additionally the costs saving related with the in-house manufacturing adds to the attractiveness of such an approach. The paper aims to present that with the advent of new technologies e.g. 3D printing it becomes possible for simple-design tools capable of delivering high quality results to be created by virtually anyone.
