The effective non-lethal range of an AHD depends on the total acoustic output of the unit. Typically, this range is 50 metres (160 ft) or less. In addition to its "voice" feature, which acts as a loudspeaker , the LRAD has an "alert" feature, which emits loud chirping or beeping sounds, which can be used at the top of the decibel range of the ...
The multiple entry horn (also known under the trademarks CoEntrant, Unity or Synergy horn) is a manifold speaker design; it uses several different drivers mounted on the horn at stepped distances from the horn's apex, where the high frequency driver is placed. Depending on implementation, this design offers an improvement in transient response ...
A horn loudspeaker is a loudspeaker or loudspeaker element which uses an acoustic horn to increase the overall efficiency of the driving element(s). A common form (right) consists of a compression driver which produces sound waves with a small metal diaphragm vibrated by an electromagnet, attached to a horn, a flaring duct to conduct the sound waves to the open air.
A patent horn loudspeaker. Loudspeakers are often built into horn-shaped enclosures or use horns. Most often the higher-frequency elements (tweeters and midranges) use horns, sometimes with acoustic diffraction lenses to spread the sound waves in a horizontal pattern at ear-level and limit the vertical pattern. An audio driver (e.g., a speaker ...
Lethal Company is a cooperative video game for up to four players played in first-person perspective. Set in a retro-futuristic setting, players work as contracted employees of "The Company". They can communicate with each other through the in-game proximity chat , as well as proximity text chat.
Community Professional Loudspeakers is an American manufacturer of loudspeakers and sound reinforcement equipment.The company has been located in the Philadelphia area since its inception in 1968, and has occupied its present location in Chester, Pennsylvania since 1981.
Horn-loaded compression drivers can achieve very high efficiencies, around 10 times the efficiency of direct-radiating cone loudspeakers. They are used as midrange and tweeter drivers in high power sound reinforcement loudspeakers , and in reflex or folded-horn loudspeakers in megaphones and public address systems .
The P-series horns have longer bells and a heavier manifold than the M-series. [3] The name of the horn is a P followed by the bells that face forward, followed by R if any are reversed, and then the numbers of the reversed bells; a P12345 is a true five-chime horn with all bells facing forward, while P135R24 has bells 2 and 4 reversed.
