Microphone and preamplifier system designed for low frequency testing

A new ½in (12mm) microphone and preamplifier system, model 378A07 designed for use in low frequency testing and ideal for studies ranging from wind turbines to natural events like tornadoes has been introduced by PCB Piezotronics. Low frequency measurements are commonly required for wind turbines, sonic booms, diesel engines and specialised loudspeaker systems to name a few.

Natural events such as tornadoes and earthquakes emit very low frequency pressure waves which can travel long distances without being blocked.

Model 378A07 microphones can detect these low frequency signatures as potential danger. This free-field pre-polarised microphone has a frequency range of 0.13Hz to 20kHz (±2dB) which meets the IEC 61094-4 standard for test and measurement microphones.

This covers infrasound which is below the normal hearing range for adults.
