Sound Meter PRO
Sound Meter PRO is professional sound meter for yourAndroid.SoundMeter is also known as sound level meter, decibelmeter (dBmeter),noise meter, sound pressure level meter (SPLmeter). SoundMeterPRO uses your Android's microphone to measurelevels of noiseorsound pressure levels and displays measured datain dB(decibels)with reference to generally known noise (providedbyAmericanAcademy of Audiology) or displays the noise data on easytoreadgraph for the last 30 seconds of app use. MicrophonesinAndroiddevices are made to record human voice, thereforethemaximum noiseis limited and very loud sounds cannot berecognized(in most casesabove 100dB). Sound Meter PRO is calibratedto beaccurate in +-2.5dB range of actual noise level and isprobably byfar the mostaccurate sound meter on Google play. We haveadjustedSound MeterPRO with the use of professional sound meterused bysoundengineers and made required adjustments for manyAndroiddevices,including the most popular devices on the markettoday.Levels ofNoise In decibels (dB) according to American AcademyofAudiology(www.audiology.org): 140 dB - Gun shots, fireworks 130dB-Jackhammers, Ambulance 120 dB - Jet planes taking off 110dB-Concerts, Car horns 100 dB - Snowmobiles 90 dB - Power tools80dB- Alarm clocks 70 dB - Traffic, vacuums 60 dB -Normalconversation50 dB - Moderate rainfall 40 dB - Quiet library30 dB -Whisper 20dB - Leaves rusting 10 dB – Breathing Why wouldyou useSound MeterPRO? Measure the noise your neighbors make, checknewcomputers,refrigerators, air conditioning units before yourbuythem fornoise levels and select the more quiet ones, to havelessnoisepollution in your home. Measure how loud your car,motorcycleis.Adjust the sound system for the party you are makingto safelevelsnot to damage peoples hearing. Measure the noise intheapartment,house you are about to buy, it might be too noisy tolivein anddemand for extra noise insulation. Measure your loveonessnoringlevels and show them the graph after. Possibilitiesareendless,Sound Meter PRO is a must have app for everyAndroiddevice.

Acceleration measurement and determination of therelevantfrequency,the acceleration and the amplitude of theoscillationExplanation ofthe buttons arranged on top of the screenCONTI:Continuousmeasurement 5 SEC: Fixed measurement duration of 5sec,then STOPautomatically STOP: Stop of measurement, the last5seconds aredisplayed -: In stop mode, move zoom window(1.28sec)to the left,only for PRO version +: In stop mode, movezoom window(1.28sec) tothe right, only for PRO version There aresevenfigures below thebuttons. Upper figure "Currentaccelerationvalues": Theaccelerations values are displayed. Thesamplingfrequency of mostsmartphones is 50 Hz. If the actualsamplingfrequency deviates by ±1 Hz, then the actual samplingfrequencyappears (flashing).Different times must then becorrectedaccordingly. The numericallydisplayed measured valuesarecorrected automatically. During a swipeaction "from bottom lefttotop right", the APP goes into adiagnostic mode. Then theactualsampling frequency, the standarddeviation of thesamplingfrequency and an internal counter appear.Underneathfigure"Accelerations over time": It shows theaccelerations curveof thelast 5 seconds. After pressing STOP, awindow of 1.28 sec ismarked(vertical black bars). in PRO version:the window can bemoved by±, after a double-tap on the figure itappears twice aslarge,after another double-tip it is resized again.Swipe up, swipedownto change the scaling. Underneath figure"Largest of thethreeacceleration components curve": It shows theaccelerationcomponentwith the maximum acceleration change. The zoomwindowisrepresented by 1.28 sec. It is particularlysuitableforoscillation frequencies from 1 Hz to 15 Hz. The moresinusoidalthetime signal, the more secure are the determinedvalues.Indiagnostic mode, trigger points and sineapproximationsarevisible. In PRO version: after a double tip on thefigureitappears twice as large, after another double-tip itisresizedagain. Swipe up, swipe down to change thescaling.Underneathfigure "Numerical evaluation from the timesignal":Hereevaluations from the time domain are displayednumerically. Inthediagnostic mode, the number of detectedvibrations aredisplayed.Sx is their standard deviation. The largern and smallerSx, thesafer the values determined. The accelerationamplitudealsospecifies a standard deviation. The calculation isdone withtheleast square method. Underneath figure "FFT-writingoftheacceleration over time": Here, a plot of theaccelerationspectrumover time is shown. Shown are the last 5seconds. The zoomwindowis marked.
