Vibrations! 2.6 APK
jjbunn
Vibrations is an app for measuring mechanical vibrations andacoustic noise from engines, the environment, machines, and otherequipment. This is (currently) the only app that combines acoustic*and* mechanical measurements! Uses: monitoring vehicle enginevibration, monitoring vibrations of household appliances(dishwasher, refrigerator, waste disposal units, clothes dryers,etc.), measuring g-force in moving vehicles, helping to identifyfailing gears, evidenced by knocking sounds, modes, etc..Vibrations uses data streams from the built-in accelerometer andmicrophone: it calculates two simultaneous FFTs, one from themechanical measurements, one from the audible measurements. It thenshows the frequency spectra on the screen. The frequency axis islabelled in Hz and RPM (revolutions per minute). Four on-screensoftware gauges give an overview of the measurements: 1) Theg-force (excluding gravity), which measures acceleration 2) Thefrequency of the current peak in the mechanical/vibration noise 3)The frequency of the current peak in the acoustic noise 4) Thesample rate at which mechanical vibrations are being measuredScreen shots can be taken using the "Save Screen" button, andstored to the SD card. Time series of accelerometer data (up to 20seconds) can be recorded and saved using the "Record Data" button.Since data are continually being gathered, the recorded datawritten to the file actually starts a second or so *before* thebutton was pressed. Recording can be interrupted while in progress,and the data discarded or saved. Otherwise, the recording willautomatically terminate after 20 seconds have elapsed, and the datadiscarded or saved then. Data collection can be paused and resumedusing the "Pause"/"Resume" button. This is the first release ofthis app, and ideas for improvements/enhancements are welcome:please contact me. Also, please note that the frequency limit ofthe mechanical vibration measurement is limited by the maximum ratethat accelerometer samples can be obtained from the Android device:this typically varies from device to device - e.g. on the Nexus 7and 10 tablets, the rate is ~200 samples/sec, giving a maximumfrequency measurement of ~100Hz or 6000 RPM. On the Galaxy S3 therate is ~100 samples/sec, giving a maximum frequency of ~50Hz.
