Noise meter

Description

This App is a full featured sound level meter, designed by a signal processing expert. It is iPhone/iPod/iPad compatible and adapts itself to the actual screen resolutions ("HD", "retina").
It consists in two parts: half top for basic features, half bottom for advanced ones (L95, %D, ...).
Half top was thus designed to be extremely easy to use. Only two settings are requested:
* select 'fast' or 'slow' update rate, which corresponds to 2 different integration periods
* select the type of weighting: A or C or Z (Z meaning roughly: no filtering)
These settings are saved when exiting the App.
Some tips for weighting:
* select A to evaluate the feeling of a person against a noise
* select Z to balance an audio system
Supports upside-down orientation.
The min and max values are monitored and displayed in green in the upper view. An average value (Leq, LAeq, ...) is computed on top of this: the green triangle. Take care that this latter corresponds to the logarithm of the average power and not to the average of logarithm values, which is completely different. Integration time for this average value is: all time since start-up of the App or last reset.
To reset these extreme and average values, touch the text named RESET.
Bottom view is used to display an historical curve. A grid is visible, with lines every 10dB vertical and 10s horizontal.
Half bottom now:
* a real-time histogram is displayed on left side
* it can compute L%: L95, L50, ...
* it can make some dosemetering: for this you need to set threshold, criterion and exchange values. This is for advanced users due to the complexity of underlying concepts
As for all sound-meter (at any price, hardware or software), you should calibrate it against a reference in order to achieve best accuracy. For this go to Mic. tab to add or remove a fixed offset to the measured values.

Outil indispensable !

Dispose d'une fonction absente de la plupart des applications équivalentes sur iPhone : La mesure du volume sonore moyen sur une période. Indispensable pour moi ! Bravo.

Indispensable !

Sonomètre précis, très simple a utiliser, que demander de plus ? Avec cette application votre iPhone devient un sonometre pratique pour régler un home cinema par exemple ! Je recommande !
