Model 426B02, ½” In-Line A-Weight Filter

01 February 2006

February 1, 2006, Depew, NY, USA – The Vibration Division of PCB Piezotronics, Inc. (PCB®) introduces Model 426B02, 1/2” in-line A-Weight filter, which operates from ICP® sensor power and is designed to work with prepolarized microphones. The human ear naturally attenuates certain frequencies. This filter is designed to simulate how a sound pressure level, at different frequencies, would appear to a normal human ear. It is commonly used in automotive, aerospace, and appliance testing applications, among others, where manufacturers are concerned about how the human ear perceives sound pressure levels at the different frequencies generated by their products. The goal is for safety or to make the sound as pleasing to the ear as possible. The Model 426B02 can be attached directly to the ½” preamplifiers BNC connector, or between the preamplifier and a 4 to 20 mA constant current supply, via low cost coaxial cables.

This ICP® design allows for significant savings in power supply and cabling cost, greater ease-of-use and operates from the same power required for ICP® accelerometers. This provides the advantage of using microphones with ICP® accelerometers in the same test, with the same signal conditioning equipment, minimizing set-up time.
