The Vibration Division of PCB® Piezotronics, Inc. intro- duces a new accessory model to its acoustic product line. Model 079B21 is a Nose Cone designed to be used with 1/2” (6 mm) condenser test and measurement microphones. The 079B21’s aerodynamic shape is designed to minimize noise due to wind and other high-speed laminar flows, while permitting the sound
intended to be measured to pass through. Another advantage of the nose cone is its ability to protect and minimize damage to the diaphragm due to sand, dirt and other contaminates that might be picked up and directed toward the microphone by the wind. Typical applications are wind tunnel testing and outdoor envi- ronmental testing. Web: www.pcb.com
The RION NA-28 A-28 Sound Level Meter and Real Time Analyzer is the successor to the popular NA-27. The NA-28, with a high-contrast TFT-LCD color display, simultaneous measure- ment and display of 1/3rd and 1/1 octave bands, uses memory card storage (with up to 300,000 data sets stored). Along with com-
parator output, optional uncompressed WAV file recording, from 12 to 20k Hz frequency response, and simple operation, a RION tradition, the meter is a pleasure to hold and to read. Scantek, Inc., an ISO 17025 NIST accredited Calibration Laboratory, is a distrib- utor for RION. Web: www.scantekinc.com
