Description

Valid data and efficient test methods have always been important in acoustic noise, vibration and harshness (NVH) testing, but the need for better test methods and more reliable data has never been greater. New types of cars – electric, hybrid, autonomous – pose new challenges and call for new, informed and clever trade-off decisions. Add to this, the constant push for shorter time to market and more efficient NVH test methods - more urgently than ever before. Automotive noise testing can be extremely demanding, so you need a robust solution to meet your expectations. This is why GRAS has developed the 146AE - a measurement microphone specially designed to perform under realistic test conditions. Setting up multichannel measurement systems many times a day exposes your microphones to shock and drop. It is important that your test systems are protected against vibrations, extreme temperatures, high humidity, dust and even oil mist. The focus has been on ensuring that the 146AE performs in real-life conditions. Ideal for engine compartment measurements, transmissions, exhaust and brake noise tests. These conditionas are all verified during our Highly Accelerated Lifetime Test (HALT). Watch the video about HALT test for GRAS 146AE here. To enable efficient testing you also have to trust that your microphones are ready and working when you roll a vehicle into the test chamber – and confident that your data is accurate when you roll it out again. Our answer is the 146AE - the measurement microphone set that is so rugged and well protected that it can be trusted as your standard microphone for the broadest range of automotive noise,
