A sound baffle is a construction or device which reduces the strength (level) of airborne sound. Sound baffles are a fundamental tool of noise mitigation, the practice of minimizing noise pollution or reverberation. An important type of sound baffle is the noise barrier constructed along highways to
A pair of headphones being tested inside an anechoic chamber for soundproofing. Soundproofing is any means of impeding sound propagation.There are several methods employed including increasing the distance between the source and receiver, decoupling, using noise barriers to reflect or absorb the energy of the sound waves, using damping structures such as sound baffles for absorption, or using ...
A submarine tracking another submarine can take advantage of its target's baffles to follow at a close distance without being detected. Periodically, a submarine will perform a maneuver called clearing the baffles, in which the boat will turn left or right far enough to listen with the forward array sonar for a few minutes in the area that was previously blocked by the baffles.
An inner perforated layer of light gauge sheet metal (baffle) The baffle is then filled with sound-absorptive insulation In high velocity systems, or when there is a concern for particulate matter in the air stream, a bagged or mylar-faced insulation is used. Packless sound attenuators do not include sound-absorptive insulation.
Drained circular sedimentation tank showing central inlet baffles on the right with solids scraper and skimmer arms visible under the rotating bridge. Although sedimentation might occur in tanks of other shapes, removal of accumulated solids is easiest with conveyor belts in rectangular tanks or with scrapers rotating around the central axis of ...
Centrifugal type spark arresters employ stationary vanes, baffles, or other devices to trap large particles by centrifugal force. These spark arresters are typically found on heavy agricultural and construction equipment (tractors, combines, bulldozers, etc.), but some have been developed for motorcycles and other all-terrain vehicles.
Tree baffles: bands and cones These tree wrappings are sometimes called baffles. However, most baffles available online are designed for bird feeder poles or trees with small-diameter trunks.
Baffle (liquid mixing), auxiliary devices employed in tank which suppress the effects of slosh dynamics; Baffle (heat transfer), a flow-directing or obstructing vane or panel used in some industrial process vessels (tanks) Baffle (medicine), a tunnel or wall surgically constructed within the heart or primary blood vessels to redirect blood flow
