Why One Rugged Microphone Outperforms Multiple Standard Sensors

February 6, 2026

In the world of automotive testing, technicians and engineers often face a classic dilemma: choosing between laboratory-grade precision and field-ready durability. Frequently, microphones that offer high precision are too fragile for road tests, while rugged microphones may lack the accuracy required for high-frequency analysis.

At Haliatech, we understand that true innovation requires the right tools. Through our partnership with Axiometrix Solutions (GRAS), we are introducing a new standard in NVH (Noise, Vibration, and Harshness) measurement: The GRAS Rugged Series (146AE & 147AX).

One Microphone, Diverse Applications As illustrated in the GRAS “Application Wheel,” flexibility is the key to modern efficiency. Utilizing the 146AE series allows you to handle various testing scenarios without the need to constantly switch sensor types:

Engine & Powertrain Noise: Withstand high engine bay temperatures and intense vibration without data distortion.
Pass-by & Wind Noise: Maintain high reliability against environmental elements such as dust and humidity during exterior testing.
Brake Noise: The compact form factor allows for easy installation in tight spaces near the braking system.
Vehicle Interior & BSR (Buzz, Squeak, Rattle): Low noise floor ensures the detection of subtle sounds that impact cabin comfort.

Why You Should Upgrade Now Future-proof testing demands faster and more valid data. By utilizing microphones specifically designed for extreme conditions, you significantly reduce the risk of test re-runs caused by sensor failure. This is not just about replacing old equipment; it is a strategic move to enhance your overall measurement capabilities.
