They cover requirements for free-, randomand pressure-field measurements. They are the latest in Brüel & Kjær's range of precision microphones for accurate and reliable electro-acoustic, IEC or ANSI sound measurements. Their corrosion resistance has been improved and their temperature range has been extended. They are the result of a new and robust design which ensures greater reliability and accuracy. Introduction The six 1/2 condenser microphones of Brüel & Kjær's FalconTM Range cover, between them, a very wide range of needs and applications. They are the culmination of 40 years of leadership in top quality condenser microphones for precision acoustic measurements. These FalconTM Range microphones will meet your demands whether they be in complying with ANSI or IEC standards or in acoustic research. Robust and Stable They are robust and suffer less than a ±0.1 dB change in sensitivity when Microsoft is a registered trademark and Windows is a trademark of Microsoft Corporation subjected to an IEC 68-2-32 1 m drop test onto a hard wooden block. They are made of carefully selected materials and alloys to ensure excellent stability and are virtually unaffected by industrial and similarly hostile environments. Furthermore, each FalconTM Range microphone comes with an extended guarantee period of three years. During manufacture, each microphone is artificially aged at a high temperature to ensure good longterm stability. No ecologically damaging materials are used in the manufacture and packaging of these microphones. The Types 4189 to 4193 are packaged as shown above. Selecting a Microphone for Your Needs To make sure you select the right microphone to match your needs, you will probably have to consider one or more of the following: Standards (IEC or ANSI) Free- or pressure-field response Frequency range Polarization (0 V or 200 V) Brüel & Kjær B K Start Yes Standards No ANSI ANSI or IEC 651 IEC Pressurefield Free-field or Pressure-field Freefield S 1.4 1983 Type 1 or S 1.12 Type M S 1.4 S 1.12 Type 0 and Type 1 Type 0 Type 1 Infrasound No Aud |
