Paging Horns
A paging horn is a loudspeaker that uses an acoustic horn to increase the efficiency of sound. The most common form consists of a device that makes sound waves using a diaphragm that is then vibrated by an electromagnet that is attached to a horn. There are other types of horns that you could buy, as well, but these are the most common. These are great for warehouses, ballparks, theaters, and other places where you might need to project sound over a large area.
There are several different types of paging horns that you could choose from depending on the size of the area that you are trying to project sound over. You can get some kinds that are better for indoors and some that are better for outdoors. Some are PA paging horn speaker & outdoor horns that you can use outdoors. There are also some for smaller spaces and for larger spaces so that you can customize them for your needs.
The biggest advantage of these horns is that they can produce about ten times more power for sound than a typical cone speaker. The biggest disadvantage that they have is that their frequency response can be uneven. They need to be big so that they can become cumbersome so that they can get the right response at bass frequencies. These were first introduced in the early parts of the twentieth century.
This article will help you to learn more about paging horns and their uses. You can learn about some of the different types that exist. You can also do more research to find the information that you may be seeking.
History
The horn has a history that goes back to before the Second World War and was originally used as a loudspeaker for early phonographs. Learn more about them here. You might remember the famous painting in which a dog was listening to a phonograph. These were popular in the days before electrical sound production because they were necessary to increase the sound.
The megaphone was another early horn that was first used as a way to amplify the human voice. The earliest forms of the megaphone were just rolls of paper that were used. More advanced forms are still used by lifeguards and cheerleaders to amplify their voices. They have a classic sound to them that makes your voice sound high and tinny, so they weren’t good for amplifying phonographs.
Applications
These horn speakers have many applications in the world today, especially for public address systems and concerts. The drivers in these horns are small and compact but they still allow for those bass frequencies that are important. They can be made to reproduce a range of frequencies that use a single driver that does not need to have a crossover to use. Although they are great for public address systems, they can sound funny because of the way they disperse the sound.
They are great for concerts, as well, but they must be used in combinations and can’t be used alone. They use subwoofers so that concertgoers can not only hear the bass but can feel it. This provides a better concert experience for concertgoers. Multiple horns are used to help spread the sound around the concert venue so that everyone gets a similar experience.
These speakers are also great for commercial theaters because of the way they work. Horn-loaded loudspeakers are used for pattern control that also increases the sound sensitivity that is needed to fill a large room. This allows customers to be able to hear the bass when needed, as well as the other sounds that are much quieter. This increases the theater experience for the customers that came to see and hear wonderful movies.
They are also good for home theaters and for audiophiles who want a commercial experience for their homes. They are a good match for the lower powered amplifiers that are less expensive to use. They do provide a distortion that some people don’t like, but they still provide the experience that many people are looking for. They are perfect for most home uses because they are inexpensive but still provide the sound that people want.
Different Types
There are different types of paging horns that you can use in a variety of situations. One is a Hybrid Constant Directivity, or HSD, that will turn any expansion horn into a constant direction horn: https://www.speakerlab.it/resources/HCD.pdf. The algorithm provides a low distortion level compared to CD horns especially at sound pressure levels that are higher. This makes it good for theater use, either in the home or in commercial theaters.
A multiple entry horn was designed in 1996 by Ralph Heinz and will include multiple drivers for high and mid bandpasses. There are also designs that have more drivers that allow for other frequencies. They have four mid-frequency drivers and two low frequency ones that allow for the sounds that you are looking for. These are best for public address systems because of the sounds they produce.
Waveguide horns are those that have low acoustic loading and are designed to control the radiation patterns. All these horns provide some control over patterns, so the differences are just a matter of judgment. They can be used in all areas where other horns can be used, so you need to decide which one will fit your needs the best.
Oblate spheroid waveguide horns are designed to upgrade the directivity pattern controls that are above the 1 kHz levels and work with a lower frequency to match the mid-range drivers. They are best for outdoor uses and for home theater uses. They can be used in other arenas, as well, but these are the best uses for them.
Conclusion
There are many different types of paging horns that you can use in a variety of ways. They are good for public address systems, concert halls, theaters, and homes. They were first made in the early twentieth century and have come a long way since then. Almost everyone has used one or heard one used in one of the venues that have been mentioned.
