Sound Pressure Analysis For Closed-Box Loudspeaker Enclosures

Document Thumbnail

This study employs a physical modeling method to explore the pressure distribution within typical closed-box loudspeaker enclosures of different shape and inner volume. The simulation results are compared to measurements in such enclosures. The results indicate that sound pressure within such enclosures often exceeds levels of 130 dB. The pressure profile is usually constant at lower frequencies and displays some strong resonances at higher frequencies due to normal modes. Such levels traditionally challenge enclosure air-tightness, box rigidity, but they can also provide useful acoustic energy for harvesting.
