SPEmittedFind

SPEmittedFind is a professional calculation tool focusing on acoustic engineering and audio technology. It integrates three core calculation functions: Sound Pressure (Receiver), Sound Power Level, and Sound Power Emitted, and provides accurate data support for scenarios such as acoustic research, engineering design, and audio debugging.

Sound Pressure (Receiver): Input the sound pressure level value and reference pressure (default 1μPa), and convert it into the actual sound pressure value in real time. It supports the analysis of the sound pressure signal at the microphone receiver, and is suitable for scenarios such as noise monitoring and audio debugging.
Sound Power Level: Automatically derive the decibel value of the sound power level through sound pressure level, distance, and sound field environment parameters (free field/semi-free field), and assist in the energy evaluation of sound sources such as speakers and mechanical equipment.
Sound Power Emitted: Combine the sound pressure level measurement data with the sound field radius to quickly infer the emitted sound power of the sound source, and support professional needs such as noise source positioning and architectural acoustic design.

The APP has built-in unit conversion (dB/Pa/W), environmental parameter preset (temperature/humidity correction) and history recording functions. The interface is simple and intuitive, suitable for engineers, students and acoustic enthusiasts, making complex acoustic calculations more efficient and convenient.
