PROBLEM TO BE SOLVED: To provide a mobile terminal, a vibration sound measuring system, and a vibration sound measuring method that can improve the efficiency of maintenance and diagnosis of rotary machines.SOLUTION: A mobile terminal comprises photographic means, sound collecting means, object detecting means, signal processing means, and signal analyzing means. The photographic means photographs an image of a photographic object. The sound collecting means measures sound radiated by the photographic object. The object detecting means detects a measurement object from the image photographed by the photographic means. The signal processing means converts the radiated sound measured by the sound collecting means into a digital sound signal. The signal analyzing means, if the object detecting means has detected the measurement object from the photographic object, analyzes the sound signal under preset analytic conditions and thereby diagnoses the state of the measurement object. |
