OpeNoise vs PAcalculate Utilisation & Stats
OpeNoise is a real-time noise level meter.
TECHNICAL SPECIFICATIONS:
- Real-time A-weighted sound pressure level measurement
- Minimum and maximum level
- Third octave and FFT analysis
- Data saving in text file
- Calibration
- Displaying measurements on a map
- Metadata compilation
- Sharing calibration and measurements with the OpeNoise community
TERM OF USE
This app is not intended for professional use, it does not necessarily guarantee an accurate noise measurement.
Since each device has a different response to noise, a comparison with a professional noise level meter in the measurement dynamic range is required.
The utilization of the app requires adequate technical knowledge and skill; an extemporary measurement might not be correct.
The calibrations and measurements sent to the OpeNoise community will be used for statistical purposes only and cannot be used in any way to verify compliance with legal limits.

28 calculators (47 calculations) for pro-audio sound reinforcement and lighting, as well as reference info and utilities. A super handy tool for people dealing with PA, sound reinforcement, sound systems, electro-acoustics, pro-audio and lighting
Acoustics
- SPL (sound pressure level). Enter sensitivity in dB SPL, power, number of loudspeakers, phase and distance
- SPL sum
- Air absorption attenuation for a given humidity, temperature, frequency and distance
- Ceiling speaker coverage
- Time «» Distance
- Audio frequency «» Wavelength (includes lambda/2 and 2*lambda/3 for line arrays or subwoofer arrays)
- Transition distance for line arrays (near to far field)
- End-fire and broadside array subwoofer modelling
Audio electronics
- dBu «» dBV «» Volts
- Q «» B/W (bandwidth)
- Limiter threshold, attack&releases times
- Amplifier gain
Cabling
- Speaker cable: low impedance, high impedance (constant voltage line, 70V/100V). Calculates energy and level loss, system damping factor
Lights
DMX channel, RGB/RGBW/RGBA and CMY
Reference info such as pinouts (proaudio and lighting) and graphs
