Special Microphones for Advanced Acoustic Testing

Special Microphones for Unique Acoustic Measurement Needs

In many advanced acoustic applications, standard microphones may not meet the specific demands of unique measurement setups. That’s where special microphones come into play. Designed to handle complex or unconventional acoustic environments, GRAS special microphones offer precision, reliability, and adaptability for a wide variety of specialized testing scenarios.

GRAS categorizes its special microphones into multiple types, each engineered for targeted use cases:

  • Array Microphones are optimized for multi-channel measurements, ideal for applications such as beamforming and sound field mapping.

  • Flush-Mount Microphones are designed to be embedded into surfaces without interfering with airflow, commonly used in wind tunnels and vehicle interiors.

  • Infra-Sound Microphones are capable of capturing extremely low-frequency sound, useful in seismic or environmental studies.

  • Intensity Microphones and Probes are built for measuring sound intensity and directionality, enabling accurate sound power assessments.

  • Lownoise Measuring Systems are developed for detecting very low-level acoustic signals, such as in quiet product testing or sound insulation evaluation.

  • Outdoor Microphones are rugged and weather-resistant, suited for long-term environmental noise monitoring.

  • Plate Microphone Kits provide integrated solutions for measuring sound reflection on surfaces like panels or windows.

  • Probe Microphones are used for narrow or hard-to-reach spaces, offering reliable measurements in small cavities or ducts.

  • QC Microphones are specifically designed for high-speed production line testing, balancing accuracy with durability.

  • UTP (Ultra-Thin Precision) Microphones allow for precise placement in confined geometries.

  • Surface Microphones are intended for boundary layer measurements on hard surfaces.

  • Turbulence Screen Microphones reduce flow-induced noise, making them suitable for high-speed aerodynamic testing.

Whether for research, industrial, or environmental purposes, GRAS special microphones offer the flexibility and accuracy needed to tackle the most challenging acoustic measurement tasks.
