Measuring sound is what we do. Now, on the iPhone and iPod touch. Noisee - Worthy of the name "Sound Level Meter"

Noisee is an intuitive professional-grade sound level meter for iPhone and iPod touch. It features all the tools that are expected from a professional ANSI or IEC compliant Sound Level meter. All filters, averaging modes and statistics meet or exceed ANSI type 1 or relevant IEC Standards. Noisee is specifically tailored to meet needs of Occupational health measurements. The application was created by the team that has a 10 year experience in calibration, owning a Sound Level Meter calibration laboratory meeting the ISO 17025 requirements. The same equipment was used when developing this app.

*** IMPORTANT NOTE ***

The app has been developed with the use of internal microphones of iPhone 4 and iPhone 4S. Our tests have shown that the internal microphone has better performance than the external microphone on the factory provided in-ear headphones.

The initial calibration works incredibly well and is determined with testing in an anechoic chamber meant for calibration of professional Sound Level Meters. We do not recommend changing the initial calibration since we have established that the internal sensitivity of the microphones has insignificant variation between different iPhones.

The app makes full use of the iPhones dynamic range which is approximately 45 dB to 100 dB (re. 20 uPa) and frequency response range which is from 100 Hz to 8 kHz.

App has two modes:

***Sound Level Meter

History view for one minute time log of the measured parameter

Parameters offers a view of all the Statistics of the current measurement (Percentiles from the ISO)
-All relevant time weightings available: Fast and Slow
-All relevant sound measurement parameters are measured and indicated: Leq, LCpeak, SPL

Spectrum view offers a view of time-history of the sound Level which is frequency and time-weighted.
Special care has been taken to design the CPB (Constant percentage bandwidth) frequency analysis according to the IEC 1260 and ANSIS1.11.


***Noise at work

Occupational Health compliant parameters including: Noise DOSE, Elapsed time.
Special parameters: LEX 8h, Projected DOSE, Time to reach 100% DOSE (in hh:mm:ss).

***Settings
- Sound Level meter weightings (Frequency weighting, Time weighting)
- Noise at work parameters (Standard, Exchange rate, Time Weighting)
- Microphone selection
- Calibration

***Sleek app design that is specially appropriate for any light conditions.

* Professional grade external microphones have not yet been tested.
