Reference Microphone

Reference microphones are crucial for accurate sound measurement and analysis, serving as the benchmark against which other microphones or audio processing techniques are evaluated. Current research focuses on improving microphone performance, particularly in reducing distortion and enhancing signal quality through post-processing techniques and advanced signal processing algorithms, including those leveraging deep learning and complex-valued neural networks. These advancements are impacting diverse fields, from improving the accuracy of speech recognition and sound event localization in challenging acoustic environments to enabling more reliable remote data collection for phonetic research and advancing hearing aid technology.
