AWA14424C-S01C 1/2" Pressure-Field Infrasound Microphone Set
Industry-leading low-frequency extension: 0.2 Hz lower limit delivers exceptional infrasound sensitivity, capturing extremely low-frequency events beyond the range of most conventional microphones
Purpose-built for infrasound applications: uniquely suited for specialized measurement scenarios such as infrasound monitoring and sonic boom detection
Flat, reliable frequency response: consistent 0.2 Hz–16 kHz response ensures accurate amplitude representation across the full measurement range, minimizing distortion in low-frequency data
High sensitivity performance: precise capacitive microphone design provides strong, reliable output even for very low-amplitude, low-frequency signals
Pressure-field measurement accuracy: optimized sensor design suited for pressure-field applications, ideal for enclosed spaces, cavity measurements, and small-volume acoustic testing
Simple power requirements: operates from a standard low-noise constant voltage source (5–18 V, 15 V recommended), simplifying integration with common laboratory power supplies

Features
Applications of the Pressure-Field Infrasound Microphone Set
The pressure-field infrasound microphone set features a wide frequency response range, extending down to 0.2 Hz. It is suitable for various measurement scenarios, including infrasound and sonic boom measurements, and is widely used in fields such as acoustic research and electroacoustic testing.
Compatibility
The AWA14424C-S01C pressure-field infrasound microphone set requires an external low-noise constant voltage source module for operation. The source should provide a voltage between 5 V and 18 V (15 V is recommended) and support a load current greater than 10 mA.
Calibration
Each infrasound microphone set is calibrated at the factory using traceable calibration equipment, and a calibration certificate is included with every unit. Annual recalibration is recommended.
Quality and Warranty
All Aihua infrasound microphones utilize second-generation alloy diaphragms, high-strength protective grids, and synthetic corundum insulators, ensuring exceptional stability and reliability. Compared to traditional nickel or stainless steel, these alloy diaphragms offer superior corrosion resistance, high-temperature stability, impact resistance, and specific strength. To ensure the highest quality, all sensors are assembled and tested in a Class 1000 cleanroom. The infrasound microphone cartridge comes with a one-year warranty, backed by comprehensive after-sales support.
