PCB Piezotronics, Inc., announces the training class, “Microphone & Acoustic Fundamentals and Advanced Applications” to be held in Gaithersburg, MD on May 12, 2016.
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.
· 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 and testing to MIL-STD-1474E – design criteria for noise limits and operational effectiveness.
· Understanding transmission loss – key terminology/definitions, measurement equations, single and multi-panel issues and measurement techniques (two room and four microphone impedance methods).
