Phone EMF Detector vs Decibel X - Pro Sound Meter Usage & Stats

Electromagnetic field (EMF) helps you understand the radiation around you. Once you know how much EMF is there around you or how much you is causing the radiation. You can avoid places where there is high EMF to not risk your life with radiation. Phone EMF Detector detects magnetic field exposed on your phone networks using multiple ways. Move near suspected device your phone and its generates how much is the EMF radiation. Detects magnetic field to get better result with how much radiation is around you. It is really harmful and you need try to stay away as much as possible. Main Feature : There are three ways to detect EMF a. EMF Meter : Move your device and check your EMF value in meter with its calibration value and also check EMF if it is low, moderate or strong easily b. EMF Digital : Check EMF value in digital way with μT unit with its X, Y, Z Values. c. EMF Graph : You can also get graphical representation of EMF radiation nearest with suspected device. Also app display what is EMF feature to understand exactly the importance and features of EMF. Electromagnetic fields are a combination of invisible electric and magnetic fields of force. They are generated by natural phenomena like the Earth’s magnetic field but also by human activities, mainly through the use of electricity.

Decibel X - Pro Sound Meter

"Decibel X" is one of very few sound meter apps on the market that has highly reliable, pre-calibrated measurements and supports frequency weightings: ITU-R 468, A and C. It turns your phone device into a professional sound meter, precisely measures the sound pressure level (SPL) all around you. This extremely useful and beautiful sound meter tool will not only be an essential gadget for many uses but also bring you a lot of fun. Have you wondered how quiet is your room or how loud is a rock concert or sport event? "Decibel X" will help you answer all of those. WHAT MAKES "DECIBEL X" SPECIAL: - Trusted accuracy: the app is carefully tested and calibrated for most devices. The precision is matching with real SPL devices - Frequency weighting filters: ITU-R 468, A, B, C, Z - Spectrum analyzer: FFT and BAR graphs to display real time FFT. Those are very useful for frequency analysis and musical tests. Real time predominant frequency is also displayed. - Powerful, smart history data management: + Recording data can be saved into a list of history records for future access and analysis + Each record can be exported as hi-res PNG graph or CSV text via sharing services + Fullscreen mode to give overview the whole history of an record - Dosimeter: NIOSH, OSHA standards - InstaDecibel to capture your dB report overlaid on photos and easily shared via popular social networks (Facebook, Instagram, etc.). - Beautiful, intuitive and carefully crafted UI design OTHER FEATURES: - Standard time weightings (Response Time): SLOW (500 milliseconds), FAST (200 milliseconds) and IMPULSE (50 milliseconds) - Trimming calibration from -50 dB to 50 dB - Standard measurement range from 20 dBA up to 130 dBA - Spectrogram - HISTO graph for plotted history of the recorded values - WAVE graph with 2 display modes: Rolling & Buffer - Real time scale level chart - Display Current, Average/Leq, and Max values with both nice and clear digital and analog layouts - Quick reference text to help you compare with real-life examples - "Keep Device Stay Awake" option for long duration recording - Reset and clear current recording at any time - Pause/Resume at any time NOTES: - Please do not expect a quiet room reading will be 0 dBA. The range 30 dBA - 130 dBA is the standard usable range and an average quiet room will be about 30 dBA. - Although most devices are pre-calibrated, custom calibration is suggested for serious purposes requiring higher precision and accuracy. To calibrate, you will need a real external device or calibrated sound meter as a reference, then adjust the trimming value until the reading matches with the reference.
