PCB Piezotronics’s new Model 130A23 high-amplitude array microphone is designed to enable research engineers to locate noise sources in appliances, machinery, aircraft, and automotive interiors. This all-in-one prepolarized microphone and preamplifier measures acoustic signals in the audible range of the human ear with the extended dynamic and frequency range often found on more expensive condenser microphones.

The Hill Acoustics Tetrahedral Test Chamber (TTC) produces consistently accurate results when measuring loudspeakers. Voice Coil received a unit for testing and details the main features and benefits of this solution intended to remove environment and measurement geometry inconsistencies. The new test chambers support loudspeaker measurements to the new international standard IEC60268-21. This article was originally published in Voice Coil, November 2014.

As Vance Dickason reminds us, November 2014 marks the beginning of Voice Coil’s 28th year as the leading information resource for the loudspeaker industry. Since the first issue in November 1987 Voice Coil stayed true to its original concept as a world-class clearing-house of information for loudspeaker engineers, manufacturers, marketing specialists, and OEM suppliers. The November 2014 edition is now available.

A tailored solution from NTi Audio for outdoor noise monitoring is now available for the XL2 Sound Level Meter. The new outdoor measurement microphone M2230-WP and the heavy-duty outdoor case ideally complement the XL2 system for unattended noise monitoring.
