Description

"Decibel X" is one of very few noise meter apps on the market that has highly reliable, pre-calibrated measurements and supports dBA, dBC. It turns your iOS device into a professional sound level meter, precisely measures the sound pressure level (SPL) all around you. This extremely useful and beautiful tool will not only be a great tool 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 MAKE IT GREAT AND STAND OUT FROM OTHER APPS:

Trusted accuracy: the app is tested and pre calibrated for all Apple devices. The precision is matching with real SPL devices

Apple Watch support: see noise level right from your wrist

Health App integration: export noise levels directly into Health app

Frequency weighting filters: ITU-R 468, A, B, C, Z

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

+ iCloud support which synchronize all history records across your Apple devices

+ Fullscreen mode to give overview the whole history of an record

Dosimeter with NIOSH, OSHA standards

Powerful calibration: Linear, Octave 1/1, 1/3, Load/save profile

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.

InstaDecibel to capture your dB report overlaid on photos and easily shared via popular social networks (Facebook, Instagram, Messages, etc.).

Support Live Activity, Dynamic Island

Support both Portrait and Landscape layouts

Beautiful, intuitive and carefully crafted UI design. Themes: LIGHT, DARK and CLASSIC

OTHER GREAT FEATURES:

Standard time weightings (Response Time): SLOW (500 milliseconds), FAST (200 milliseconds) AND IMPULSE (50 milliseconds)

MIC Gain Offset from -50 dB to 50 dB

Standard measurement range from 30 dBA up to 130 dBA

HISTO graph for plotted history of the recorded values

WAVE graph with 2 display modes: Rolling & Buffer

SPECTROGRAPH

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

NOTES:

Please do not expect a quiet room reading will be 0 dBA. The range 30-130 dBA is the standard usable range and an average quiet room will be about 30 dBA.

Although all devices are pre-calibrated, custom calibration is suggested for serious purposes requiring higher precision and accuracy. You will need a real external device or calibrated sound meter as a reference, then adjust the trimming calibration until the reading matches with the reference.
