Product Overview
The 46AE is a free-field measurement microphone set and as such optimized for all acoustic applications, where the location of the main sound source is known and the microphone can be pointed directly at it ensuring 0° incidence.
The wide frequency range makes it ideal for general acoustic diagnostics. 46AE conforms with IEC 61094 WS2F and IEC 61672 Class 1.
Regarding temperature range, see the Specifications. Should higher temperature limits be required, we recommend the GRAS 146AE 1/2" CCP Free-field Rugged Measurement Microphone Set which can be used up to 125 °C.
A front-vented version is available, 46AE-FV 1/2" CCP Free-field Front Vented Microphone Set.
Product Features
GRAS HALT
When our R&D team develops a measurement microphone, it must undergo the most demanding tests to prove that it can withstand our customers' daily test conditions. Using a series of Highly Accelerated Lifetime Tests (HALT) we ensure that our microphones live up to the high quality and precision that our customers have come to expect and trust. Our HALT tests actively accelerate the lifetime of a microphone by simulating the handling and use it is exposed to in real-life situations.
