The wait is over!  Finally, ornithologists, biologists and other researchers have access to a microphone that produces bird and other animal recordings with unrivalled accuracy and range.  No other microphone comes close! 

Place a CZM microphone in any field setting and you will be amazed at the range and clarity of its sound capture.  Ornithologists and biologists describe their bird call recordings with the CZM as ‘just like being there.’  It’s lightweight, compact and rugged for outdoor use. It’s powerful, new technology. 

“Be There” even when you can’t with the E3A-CM microphone system!

  • Range and accuracy of recordings never before achieved
  • Undertake more projects with the same or fewer staff
  • Highly portable and lightweight
  • One year ROI

CZM’s Technical Superiority

  • Capable of superlative audio pick-up exceeding 300 m (328 yds)
  • Increased pick-up pattern, up to 360 degrees radially – captures sounds from above and below
  • Higher acoustic gain without an increase in self-noise
  • Virtually no distortion of the audio signal compared to conventional microphones
  • Greater forward sound pressure gain – comparable to 24” parabolic microphone
    • One CZM is equivalent to six 24” parabolic

      CZM Microphones are used by:

      • Environment Canada
      • Canadian Wildlife Service
      • Parks Canada
      • OMNR
      • Alberta Biodiversity Institute
      • and many others

      “It’s just like being there.  It hears everything!”

      microphones; yet comes in a package less than half the size of one 24” parabolic microphone
    • CZM combined with a parabolic dish delivers the pickup power of a hyper-parabolic microphone
  • Easily configurable for stereo (two microphones, each configured in 180 degree directional pattern)
  • Plug-n-play adaptability to existing systems
  • Can be mounted vertically or horizontally

Meets Scientific Benchmarks for Data Integrity and Reliability

  • Built in reference tone ensures that recordings cannot be skewed.  Allows accurate and reliable comparisons between data recorded at different times or locations.
  • Standard listening distances for bird count surveys can be imposed
  • Interpretation variance among observers can be estimated, leading to more robust statistical analysis
  • Minimizes interpretation variance (a single observer can be used to interpret all recordings)
  • Reduces human error (wrong species identified, too late or too early in the day, inaccurate counts, etc.)

  • Builds a series of archival quality recordings for review over time
    • Useful in educational programs
    • Enables ornithologists to maintain their “ear” for hundreds of bird calls during the off season
  • Recordings of problem species can be referred to other experts for verification
  • Avoids disturbance of the natural habitat of birds and other wildlife; some birds sit quietly or leave the area in presence of humans

Reduces Operational Costs

  • Allows junior technicians with minimal training to produce high quality field recordings
  • Creates opportunity for an unlimited number of trained “ears” in the field (removing a common limiting factor on many studies)
  • Increases the number of projects you can undertake each year

Made for Rugged Outdoor Applications

  • Bioacoustical monitoring
  • Breeding bird counts (BBS); or “point counts”
  • Migratory pattern analysis
  • Ground-based acoustic censusing of infrequently vocalizing species
  • Environmental impact studies
  • Wildlife watching / recording
  • Birding recording

  • Components are strong and durable
  • Suitable for high/low temperature fluctuations; weather resistant; sensitive electronics are housed in a waterproof hard case
  • Highly portable and lightweight (everything fits into a back-pack about the size of a carry-on case)
  • Easy set-up and user-friendly; minimal user training and support required

The CZM technology, along with the E3A-CM System, provide ornithologists, biologists and other researchers with a new and much more effective option for easily and accurately recording wild-life in the field.
