Abstract

Abstract

This paper proposes a method for calibrating the sensitivity of the current-sound pressure level system in an acoustic transducer. The uncertainty evaluation and a conformity nalysis of the conversion of permissible errors are also included. The desired calibration results were obtained, which can shed light on sensitivity calibration for acoustic transducers.
- acoustic transducer,
- system sensitivity,
