• Resumen

  • A miniature loudspeaker assembly has been manufactured for acoustical scale model testing using parts for a commercially available studio monitor headphone. The loudspeaker assembly consists of a dodecahedron loudspeaker for middle and high frequency sounds and woofers for low frequency sounds, respective to the scaling required for a scale model test. The loudspeaker can reproduce sound with a frequency range from 1kHz to 80kHz (with an nearly flat response from 2kHz-40kHz), equivalent from 100Hz to 8kHz for a 1/10 scale model test. The frequency and directional characteristics of the miniature loudspeaker assembly are discussed in this paper, and some scale model test examples are introduced.
