New PCB Piezotronics 1/2” Preamplifier for Acoustic Testing in Confined Spaces

PCB Piezotronics expanded its microphone preamplifier family with the introduction of a new 1/2” short preamplifier. Model 426A13 is for test engineers and acoustic consultants taking measurements in spaces where traditional microphone systems won’t fit or where space constraints are a concern, such as under automobile engines or in a cavity.

In mid-August 2013, the SP Technical Research Institute of Sweden undertook a study to compare four brands of measurement microphones. The standards bureau had been asked to purchase four microphones of the same type from four different measurement microphone manufactures — Brüel & Kjær, BSWA, G.R.A.S. Sound and Vibration A/S, and PCB Piezotronics.

The February 2015 edition of Voice Coil is already available and features our annual Loudspeaker Cone Vendor Survey 2015. James Croft’s Acoustic Patents reviews recent inventions from Libratone (Denmark) and Genelec (Finland). Vance Dickason’s Test Bench focuses on a 6.5” pro sound midrange driver, from PRV Audio Brazil and the reissue of the famous G12H “GreenBack” 12” guitar speaker by Celestion. Mike Klasco writes about the Endumax cone material by Teijin Aramid.

PCB Piezotronics’ Dr. Chad Walber was appointed as the Acoustical Society of America (ASA) Co-TAs representative to the International Standards committee (IEC TC 29). Dr. Walber was voted into this position by a panel of his peers who are distinguished members in the acoustics field. Membership includes sensor manufacturers, consultants and end users.

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.

PCB Piezotronics introduced a new short preamplifier for test engineers and acoustic consultants taking measurements with a new design, ideal for spaces where traditional microphone systems won’t fit or where space constraints are a concern.
