Introduction 

Thank you for your purchase of a PCB high quality microphone. These microphones offer highly accurate 
and reliable acoustic measurements and are typically used in research and design applications. They are 
accurate enough for laboratory usage, yet rugged enough for field-testing. 

Sound within the typical 20 to 20,000 Hz audible range of a healthy human ear can either be pleasing to the 
ear, as in music, or unpleasant (or harmful), as in noise. As a result, many applications, from the develop-
ment of consumer products to research in acoustics, measure sound, even sound outside the range of human 
hearing. The instrument  typically used to  measure sound is  the microphone, which is  designed, like the 
human ear, to transform pressure oscillations into a corresponding voltage oscillation.

Standards 

Before selecting an acoustical instrument, it is important to identify which acoustical standards are appro-
priate for the application in which the instrument will be used. Whether for legal purposes or for quality 
assurance programs, these standards will help determine the required quality, accuracy and consistency of 
the instrument. Standards that correspond to the performance requirements, dimensions and characteristics 
of acoustical components are established for microphones, sound level meters, calibrators, or other related 
components. The most common organizations producing these standards are the American National Stand-
ards  Institute  (ANSI)  and  the  International  Electrotechnical  Commission  (IEC).  IEC  1094-4  establishes 
specifications for the mechanical dimensions and certain electroacoustic characteristics for standard indus-
trial microphones. The performance specification sheet supplied with each PCB microphone identifies the 
standards to which the microphone is compliant.

Setting up a Microphone Measurement System 

After the proper microphone has been selected, the corresponding preamplifier, cabling, power supplies, 
signal conditioning and data acquisition selections are ready to be installed. Not all of these components 
are required for all test set-ups. The figures below show typical set-ups for externally polarized and pre-
polarized microphone systems. 

A prepolarized microphone can be used with a standard Microphone Power Supply designed for externally 
polarized microphones, and its preamplifier, provided the supply voltage is set to zero.
