LEARN MORE

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 over 10 years experience in calibration, owning a Sound Level Meter calibration laboratory meeting the ISO 17025 requirements. The same calibration equipment was used for the development of this app.

EXTERNAL MICROPHONE

NoiSee has been tested with external microphone MicW i436, which is a calibrated measurement microphone complying with the Class 2 (IEC 61672) sound level meter standard. If you use an acoustic calibrator with a 1/4-inch adapter, NoiSee can perform automatic calibration.

IMPORTANT

The app has been developed to run on devices running iOS 10 or higher. After you install the app you can start measuring immediately using the internal microphone. The readings you get are as accurate as it gets, because we tested the app with different iPhone models and take into account the differences in microphones between different generations of iPhones. Our tests have shown that the internal microphone has better performance than the 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 iPhone models. The app makes full use of the iPhone’s dynamic range which is approximately 45 dB to 100 dB (re. 20 µPa) and frequency response range which is from 100 Hz to 8 kHz.
Designed by professionals and tested in accordance with relevant ISO and ANSI standards.
Multiple weighting selection with Fast and Slow time weighting, A, C and Z Frequency weightings transform your iOS device into a powerful sound measuring tool!
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 ANSI S1.11.
Interpretation of noise at work and its relevance to humans according to standards. Interpretation of noise at work and its relevance to humans is more important than mere measurements. That is why NoiSee is ideal companion to evaluate the effect of noise on what matters – human body.
Occupational Health compliant parameters including: Noise DOSE, Elapsed time.
Special parameters: LEX 8h, Projected DOSE, Time to reach 100% DOSE (in hh:mm:ss).
Professional calibration and measuring equipment was used for app development. We have used professional calibration and measuring equipment to ensure user’s confidence that only the relevant readings for iOS device hardware capabilities are displayed.
Settings:
– Sound Level meter weightings (Frequency weighting, Time weighting)
– Noise at work parameters (Standard, Exchange rate, Time Weighting)
– Microphone selection
– Manual and automated Calibration

Sleek app design that is especially appropriate for any light conditions.
