<p>Provided is an acoustic energy measuring device capable of measuring acoustic energy without being affected by standing waves, even in a closed space where standing waves can be generated, by taking not only sound pressure but also particle velocity into consideration. The acoustic energy measuring device for measuring acoustic energy is configured with a sound reception unit (1), a sound pressure calculation unit (2), a particle velocity calculation unit (3), and an acoustic energy calculation unit (4). The sound reception unit (1) performs sound-electricity conversion. The sound pressure calculation unit (2) calculates sound pressure using the output from the sound reception unit (1). The particle velocity calculation unit (3) calculates particle velocity using the output from the sound reception unit (1). Then, the acoustic energy calculation unit (4) calculates acoustic energy using the outputs from the sound pressure calculation unit (2) and the particle velocity calculation unit (3).</p> |
