What are the main differences between a line array and a point of source sound system?
Line array systems work best with low and mid-range frequencies, while point source systems provide a full range of sound without additional modifications.
Are column array speakers good?
Vertical line arrays and column speakers tend to provide good control of the vertical coverage, but provide a predetermined horizontal. Depending on the aspect ratio of the room and the horizontal reverberation character of the space, point source speakers can perform better than a line array in this regard.
What is line source pollution?
A line source, as opposed to a point source, area source, or volume source, is a source of air, noise, water contamination or electromagnetic radiation that emanates from a linear (one-dimensional) geometry.
What is point source in noise pollution?
A point source of pollution is a single identifiable source of air, water, thermal, noise or light pollution. A point source has negligible extent, distinguishing it from other pollution source geometries (such as nonpoint source or area source).
What are the best line array speakers?
Top 5 Best Line Array Speakers

- Bose L1 Compact – For vocal.
- QSC KLA12 – Portable.
- ProReck Club 4000 – Very reasonable price.
- ProReck Party 10 – Fairly portable.
What do line array speakers do?
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.
What are 3 sources of point pollution?
EXAMPLES OF POINT SOURCE POLLUTION
- Industrial plants/factories (e.g., oil refineries, pulp and paper mills, chemical manufacturers, automobile manufacturers, food processors, pharmaceutical manufacturers) Pollutants: oil, thermal pollution, toxic chemicals, heavy metals, pharmaceuticals.
- Sewage Treatment Plants.
What are some point source pollution examples?
Examples include smokestacks, discharge pipes, and drainage ditches. Factories and power plants can be a source of point-source pollution, affecting both air and water. Smokestacks may spew carbon monoxide, heavy metal, sulfur dioxide, nitrogen dioxide, or “particulate matter” (small particles) into the air.
Who invented line array?
pioneer Harry Olson
The line array effect of the narrowing of the beam with increasing frequency was first demonstrated by acoustical pioneer Harry Olson. He published his findings in his 1957 text, Acoustical Engineering.
What is point source noise?
Most sounds or noises we encountered in our daily life are from sources which can be characterized as point or line sources. If a sound source produces spherical spreading of sound in all directions, it is a point source.
