Complete Audio Measurement System for environmental mesurements (Code: 1202)

Complete Audio measurement system including USB measurement microphone and software for environmental mesurements

This packackage contains an IEC61672 class 2 low noise USB measurement microphone together with a powerful analysis software optimized for enviromental noise measurements.

This measurement microphone uses a real 1/2" capsule with 12,7mm diameter. Many simple measurement microphones use a cheap 1/4" caspsule (6mm) in a 1/2"-housing. The effective area of the diaphragma is 4 times smaller. This leads to significant higher noise.
The following picture demonstrates a 1/2" capsule in contrast to a 1/4"-electret capsule.
