Affordable Measuring Microphones Shootout – Part-3

This page is the follow up of Part-2, here you will find the outcome of my measurements, pros and cons about the 1/4″ Class 2 electret capsule measuring microphone shootout.

Neutrik 3382 vs iSEMic 725TR
Neutrik 3382 vs iSEMic 725TR

Results and findings; after measuring the three microphones the first what struck me was the recorded SPL deviation between the MicW i436 and the other two microphones (the reference – Neutrik 3382, and the other measured microphone – iSEMic 725TR).
All SPL levels below 85 dB the MicW i436 measured 0.5d dB to 0,6 dB of  scale (comparing to the two other microphones).
At levels above the 85dB the differences gradually did lessen to zero around 94 dB (where it was calibrated).

Affordable Measuring Microphones Shootout – Part-1

Like me most of the audio enthusiasts are interested in measuring their own loudspeakers and/or room. A professional Class 1 measuring microphone could cost € 1000,- or more. Most people have not that much money to spend so what are decent and affordable Class 2 measuring microphones?

I’ve found and tested several 1/4″ Class 2 measuring microphones in the € 20,- to € 200,- range. They have all in common that they can be used with a mobile device (like; iPhone, iPad, Android or Windows mobile phone/tablet), but also with a notebook or PC.

For the tests I’ve used an old Neutrik (NTI) 3382 measuring microphone (with frequency correction files) as reference. The measurements were taken in my living room using a pair of bi-amped Philips VN3100-25 (OEM Stage Accompany Blue Box, SA4525). The distance between the measuring microphones and loudspeaker was set at 0.5 meter and 1 meter distances.
