Tibbetts electret microphones are a type of condenser microphone that captures sound through a vibrating diaphragm, which alters the microphone's electrical capacitance to produce an electric signal. Unlike traditional condenser microphones, which require an external power supply, electret microphones use permanently electrostatically charged elements, reducing power requirements and enabling smaller designs while maintaining excellent acoustic performance.

These high-fidelity microphones are used in a variety of applications, including hearing devices, communications headsets, surveillance, audio monitoring, lapel mics, and scientific measurements. They offer very low inherent noise, high dynamic range, and a flat frequency response, ensuring recordings closely resemble the original sound. With sensitivity as high as -33dBV/Pa, Tibbetts microphones excel in amplifying faint sounds, making them ideal for capturing soft voices, distant noises, and scientific data.
