Fiber optic sensors for temperature, strain and acceleration are well established and widely available. Here, we present a new all fiber optic acoustic pressure sensor with low noise and high dynamic range and high bandwidth. The sensor is capable of operating in very harsh environment including humidity,water, temporal overpressure, electro-magnetic noise, lightning and environmental impact such as heavy rain and thus applicable in field. Data measured during a laboratory test campaign in a flow channel in cooperation with AIRBUS GROUP Innovations are presented and compared to existing electrical microphones.
