Microphone Fundamentals &
Advanced Applications

PCB Piezotronics invites you to attend an acoustic educational seminar at the Waterford Banquets & Conference Center in Elmhurst, IL from  8:30 am to 4:30 pm on August 26th.  The keynote speaker is Andrew Barnard, Ph.D., an Assistant Professor  from Michigan Technological University and a leading authority on sound and vibration measurements.  Dr. Barnard is also INCE Board Certified and a certified LabVIEW developer. 
At this training, participants will learn:
  • Microphone/acoustic fundamentals - key terminology, acoustic waves and sound fields, the source-path-receiver model, microphone types, selecting the right microphone for your application, etc.
     
  • Sound metrics, measurement, and frequency determination - broadband metrics used to describe sound, averaging concepts, octave and third octave bands, and narrow band frequency analysis.
  • Microphone advanced applications- multichannel applications for noise source identification: sound power, intensity, beamforming, nearfield acoustic holography (NAH), etc.

  • Microphones as part of an integrated system - microphone and DAQ: how they interact and understanding the output results, system level calibration, data processing, etc.

  • Testing in wind tunnels or the outdoors - isolating the acoustic field from air flow pressure to make accurate acoustic measurements.
     
  • Understanding transmission loss - key terminology/definitions, measurement equations, single and multi-panel issues and measurement techniques (two room and four microphone impedance methods)
     
  • Pipe acoustics - material characterization using an impedance tube, muffler test cell transmission loss measurements and microphone selection
     
  •  Product demonstrations   - transmission loss, coherent/incoherent signals, sound directivity, identifying noise floor, and anti-aliasing

The cost of $99 includes lunch and training materials.
