i436 Measurement microphone
The i436 is a calibrated measurement microphone that complies with the IEC 61672 Class 2 sound level meter standard.
The sensitivity and frequency response of each individual i436 microphone is calibrated at the factory before shipping. With the i436 and a dedicated App, an iPhone or iPad can be turned into a sound pressure level (SPL) meter, or a real-time analyzer (RTA) for time and frequency domain measurements.
The omnidirectional microphone offers outstanding performance in a small package. Durable and easily carried in the pocket, the i436 measures speech, instruments and other live sounds accurately and without distortion - all on a mobile device.
