Abstract
The horn housing may comprise an inner metal shell in the shape of a hexagonal box open at one end fitting into a similarly shaped outer dense solid box similarly open at one end. Space between the inner and the outer boxes being filled by a low density sound absorbing filler, and the inner box being connected to the outer box by vibration absorbing bolts. The outer box is mounted to a structure by vibration absorbing mounting brackets. When a high decibel horn or siren is mounted in the inner box to directed sound through the opening, most of the sound propagating sideways towards the structure is absorbed by the housing increasing the comfort level of passengers or crew inside the structure.
