In the field of testing and data evaluation, the ability to efficiently collect, analyze, and interpret large volumes of data is essential for ensuring the reliability and performance of complex systems. imc STUDIO and imc FAMOS are powerful software tools that provide integrated solutions for data acquisition, measurement, and post-processing, specifically designed to address the challenges of modern testing environments. imc STUDIO offers a comprehensive interface for configuring and controlling measurement setups, enabling users to streamline the testing process, manage hardware components, and visualize real-time data. imc FAMOS, on the other hand, excels in advanced data analysis, offering a wide range of functions for processing and visualizing data, as well as generating detailed reports. This presentation explores the strengths of both software tools, demonstrating their capabilities in diverse testing scenarios such as automotive, industrial, and research applications. By combining flexibility, scalability, and high-performance analysis, imc STUDIO and IMC FAMOS significantly enhance the effectiveness of testing and data evaluation, ensuring precise results and accelerating decision-making. The presentation also discusses the seamless integration of both tools into existing workflows, making them indispensable for optimizing test operations and improving overall productivity.

Aeroacoustics is a branch of acoustics that studies noise generation via turbulent fluid motion or aerodynamic forces interacting with surfaces. It is important in the design of vehicles, such as cars or trains, to minimize vibrations, noise, and improve their aerodynamic characteristics. Measurement microphones are common tools used within this application and can measure two sources of pressure fluctuations, which are crucial in aeroacoustics: boundary layer and acoustic pressure fluctuations. The objective of this workshop is to showcase all GRAS solutions intended for acoustical measurements in airflow and to understand the differences between various designs and their correct usage through practical demonstrations.

The objective of this workshop is to showcase comprehensive measurement solutions offered by GRAS and Audio Precision, aligning with AES recommendations for In-car Acoustic measurements that describes a procedure for measuring the essential attributes of the car´s audio system. Central to these solutions is the GRAS RA0399 6-microphone array, equipped with the latest ¼” high-sensitivity microphones from GRAS. The GRAS front end will be connected to the multichannel audio analyser by Audio Precision. The ensuing data will be acquired and analysed using the powerful APx500 software. Participants in this workshop will gain insights into the straightforward setup of in-car measurements using the combined capabilities of GRAS and AP solutions. Our discussions will span various test setups, ranging from simplified to more complex configurations, all geared towards meeting AES recommendations. We will delve into the critical aspect of selecting the appropriate measurement microphone for these tests, exploring how the microphone choice influences the sound field within the car and methods to mitigate measurement uncertainties effectively. To bring theory into practice, a comprehensive test demonstration will be conducted, illustrating the automation of the entire testing process through the utilisation of Audio Precision's software. This  workshop aims to empower attendees with practical knowledge and skills essential for successful and accurate in-car acoustic measurements.
