    common sources of sound. Sound has two major characteristics: loudness, measured in decibels; and pitch, measured as frequency or cycles per second. Most sound is transmitted both by air and by the materials it strikes. For example, speech is transmitted by air until it strikes a wall and becomes structureborne. Acoustical ControlFile Size: KB.

Get this from a library. Structureborne sound in buildings: needed practical research in light of the current state of the art. [Eric E Ungar; Center for Building Technology.; Bolt, Beranek, and Newman, inc.]. Reducing Impact and Structure-Borne Sound in Buildings (IP) [Matthew Ling] on *FREE* shipping on qualifying offers.

Structure borne noise or structure borne sound is defined as noise that occurs from the impact of an object hitting a surface, like heavy footsteps falling against a floor.

The impact causes both sides of the inflicted surface to vibrate and generate sound waves. Structure-borne sound has major importance with respect to solving noise control problems: the air-borne sound Structureborne sound in buildings book (or from) the above mentioned solid structures is caused by motion of the structure surface.

In many cases it is the structure-borne sound that is responsible for Cited by: 1. Structure-Borne Sound" is a thorough introduction to structural vibrations with emphasis on audio frequencies and the associated radiation of sound.
