Sound Absorbing Acoustic Horns
Abstract
An exploratory study of acoustic horns as non-reflective liners for water-filled anechoic tanks was conducted. The goal was to determine if a suitably shaped horn could improve the reflection loss characteristics of acoustic materials. Horns were constructed and tested. In certain cases, the presence of a horn or an array of horns in an absorbing material clearly improved the process in which energy enters a material so that it may be absorbed.
