If a sound source produces spherical spreading of sound in all directions, it is a point source. If the sound source produces cylindrical spreading of sound as shown in this diagram, such as stream of motor vehicles on a busy road at a distance, it may be considered as a line source.
What is a line source in music?
A line source handles the frequency divisions in exactly the same way—tweeters, midrange, and woofers—but instead of relying upon a single driver for each range multiple drivers are instead employed, typically with a line of many tweeters and sometimes many midranges.
What is line array sound?
What is a line array? It is a series of loudspeakers that covers the same frequency range and is stacked above one another. The key to a line array is that the speakers face slightly different vertical angles, allowing them to consistently cover a greater depth of field than a single PA speaker can.
Why do line arrays sound different?
The distance between adjacent drivers is close enough that they constructively interfere with each other to send sound waves farther than traditional horn-loaded loudspeakers, and with a more evenly distributed sound output pattern.
What do you mean by point source?
Definition of point source 1 : a source of radiation (such as light) that is concentrated at a point and considered as having no spatial extension. 2 : an identifiable confined source (such as a smokestack or wastewater treatment plant) from which a pollutant is discharged or emitted.
What is the point source of light?
A point source of light is obtained by placing a screen having a fine hole, in front of a luminous body.
What is linear sound system?
In audio, linearity is a very important concern. A linear system is one whose function is even or, if it deviates, does so in a steady fashion. Logarithmic or exponential deviations are, by definition, non-linear. We’ve all heard the term “flat” used to describe frequency response. It is also linear.
What is a column speaker?
Consistent Sound Levels Front-to-Back – Like full-sized vertical line arrays, column speakers are capable of producing consistent sound levels from the front to the back of the listening space, but without cumbersome multiple enclosures.
What is point source speaker?
A point source loudspeaker is just what its name suggests: a single speaker, or multiple speakers placed far apart, broadcasting a full range of sound from a single point. Unlike the line array system, a single speaker radiates sound in a spherical pattern and therefore has less range.
What is an example of a point source?
The United States Environmental Protection Agency (EPA) defines point source pollution as any contaminant that enters the environment from an easily identified and confined place. Examples include smokestacks, discharge pipes, and drainage ditches.
What is the meaning point source?
What is a resource speaker?
To be a resource speaker is to be an expert in something that he either knows a lot about and is a specialist of due to years of studying of and experience in that topic or subject matter either as an employee, a businessman, a corporate leader, or a professor in the academe.
What is single point source sound?
A single point source sound system offers the highest possible definition and dynamic range available today. High intelligibility is a by-product of this, but is only guaranteed by maintaining this high definition and high dynamics through the use of fast and accurate electronics, with low distortion transducers.
What is a point source in music?
In physics, a drum (or piano, or any other instrument) has many multiple point sources, but in acoustics we consider the entire drum a point source. Simply put, our enjoyment of music increases tremendously when we can identify where on the soundstage an instrument is coming from.
What is multi-point source audio?
Multi point source arose from the requirements for very high output power. The idea satisfied that criteria, but with the increasing number of sound sources came an overall reduction in the quality of the sound.
What is a ‘point source speaker?
What Is A ‘Point Source’? What Is A ‘Point Source’? In physics, a point source is an energy source with negligible dimensions – a tiny, singular point in space where the energy emanates. In physics terms, a true point source speaker would be infinitely small with the ability to produce frequencies from 20Hz to 20kHz.
