The Prince Albert City Police Department uses the CZM microphone in their interview rooms, and are more than pleased with its high quality audio pickup.Interview Room

"We have been using the CZM microphone in our 'soft room' for several years and we are extremely happy with it. It has performed better than any other stationary or clip on microphone we ever tried.   The “soft room “ is where we obtain video taped statements from victims and children. We found that if a subject whispered or turned away during an interview the microphones we were using would not pick up what was said. But the CZM solved that problem, now it doesn’t matter if they whisper or turn away, or for that matter if they are over in the corner of the room, the CZM hears it all.

There are also several other major benefits to using the CZM.  All we need is the one microphone, on the coffee table, and it looks more like a modern art sculpture or something, which is an advantage for us. Of course we advise that we are recording, but they aren’t constantly reminded of that by looking at a microphone..so they can relax and focus on the interview.

We often have only one chance to interview these children before court, and the recordings do stand up as evidence. The fact that the CZM captures everything so clearly is extremely important.
Prior to using the CZM, we were frustrated by the lack of clarity of our recordings. We haven’t worried about that since we installed the CZM."

The Saskatchewan Institute of Applied Science and Technology has been using the CZM Microphone in their classrooms since 1997.

“We had been looking for a suitable microphone for our group counselling lab for some 10 years.  We need to be able to record the comments and conversation of up to 16 participants who are sitting in a circle, which can occur in various sized classrooms.  The challenge is further compounded by the fact that group participants are often highly charged emotionally and their voices go so low that we are unable to hear them and therefore lose learning opportunities.

We tested directional, omnidirectional and pressure zone microphones, and they all had serious limitations.  Since installing the CZM Microphone, however, we can easily hear several conversations going on within the group, even when a participant is highly emotional and he/she speaks in low tones or whispers.  It is so critical to capture even minute voice inflections in this setting as it helps us analyze participants’ state of mind.  We can then proceed with appropriate diagnosis and treatment programs.  So, in many respects the CZM Microphone is playing an important role in improving our teaching methodologies, as well as the counsellors’ and therapists’ diagnosis and treatment recommendations.  From our 10 years experience, we can say that the CZM Microphone is very important tool that should be part of every therapist or counsellor’s program.”

“The bioacoustic configuration described here [CZM E3A System], is appropriate for cost-effective songbird monitoring, and for the collection and documentation of sounds arising from entire bird communities occurring in different forest environments.”
