Key Features
- Measurement Mic for iOS Devices
- Lightning-Equipped Plug-In Mic
- For RTA, Measurement, and Calibration
- Works with Freely Available Apps
If you're an audio engineer, you can now measure your RTA and calibrate your monitors using your iOS device and the i437L from MicW. The i437L is an electret condenser microphone designed to execute frequency and level analyzation for audio engineers and technicians in live venues, recording facilities, and personal studios. Use the mic for SPL metering, room response measurements, and monitor calibration, effectively giving you an RTA of your space.

Can this microphone be calibrated for use with OSHA noise level screening?
Yes. You will need a good App like SoundMeter X from Faber Acoustical.
Also a calibration source, ideally with a coupler to fit the microphone. You can make an adapter for the coupler by cutting rigid plastic tubing to fit the calibrator.
You can also calibrate "free field" by using an SLM to measure nearby white noise and calibrate the App to that reading.

question
Can this measure how quiet a room with some accuracy or is it strictly loudness meter?
According to MicW, the i437L can measure sound levels as low as 30 dBA, which may be adequate for you. If you want to measure ambient levels in special rooms, such as recording studios or other spaces where sound isolation is critical, then you may need a measurement mic with a larger diaphragm (e.g. 1/2 ) to get an accurate reading of the acoustic noise floor.
