Description

The 46AD is a pressure microphone set and as such optimized for acoustic measurements of the sound source in a closed coupler or the measurement of sound pressure at a boundary or wall; in which case the microphone forms part of the wall and measures the sound pressure on the wall itself. The medium frequency range makes it ideal for general acoustic diagnostics. Regarding temperature range, see the Specifications. Should higher temperature limits be required, we recommend considering the GRAS probe microphones where the microphone and preamplifier can be isolated from the hot source. A front-vented version is available, 46AD-FV 1/2" CCP Pressure Standard Microphone Set, Front Vented. Design The GRAS 46AD is a high-performance standard microphone set. In our clean-room environment the set is assembled and sealed with a label. However, the microphone set can be dismounted, if you wish to use the components separately. Microphone The microphone cartridge is the high-quality IEC 61094 WS2P standardized GRAS 40AD 1/2" Prepolarized Pressure Microphone, High Sensitivity, designed for long-term reliability in multiple environments. Preamplifier The preamplifier is the GRAS 26CA Preamplifier which is inclusive TEDS and based on our well-known circuit board substrates. In the industry these are famous for their low self-noise, wide frequency and excellent slew rate performance.
