Fidelity Research FR-5 E

Brand: Fidelity Research

The FR-5 E is a research grade binaural probe microphone manufactured by Fidelity Research. It is designed for hearing instrument evaluation, audio research, and hearing science applications. The "E" in FR-5 E stands for "energized," indicating that it can be powered by an external preamplifier to provide high input impedance and low noise pickup. This enables it to accurately measure small acoustic signals, making it a preferred choice for audiologists, acousticians, and researchers who require precise and sensitive audio measurements. The FR-5 E also features a sturdy, ergonomic design for comfortable and accurate probe insertion into the ear canal, as well as a shielded cable and PE-10 tube connector for reliable performance.
