Low frequency sound pressure sensor (Flexiforce Pressure Sensor)

I’m currently involved in a project where I’m required to obtain sound pressure measurements in the range of 0-500 Pa, at extremely low frequencies (5-35 Hz). I have been looking at piezoelectric sensors, such as the Flexiforce Pressure Sensor, however I was unsure of the accuracy of the results at these low pressures. I was wondering whether anyone could provide me with more detail on the Flexiforce Pressure Sensor, or if they could provide recommendations for any other suitable sensors?

Hey Aidan,

I’m not sure how the flexforce meters would go, I think you might get better results with a barometer.
