How do you measure speaker coverage?
To find speaker coverage angles in the field, find the lengths of the triangle for the area you are trying to cover and solve for the inside angles. There are also plenty of free triangle solvers online and iPhone apps.
What is coverage in live sound?
The overarching goal of consistent coverage is to have no more than a 6dB variation in sound pressure level (SPL) from the loudest to quietest seat in the house. Also, consistent coverage is an ideal that’s seldom completely attainable in anything but a professional venue designed specifically for live sound.
What is speaker coverage?
Speaker coverage angle is a loudspeaker specification that, when understood, will make you better than 80%* of the other sound engineers out there. In Sound System: Design and Optimization, Bob McCarthy defines speaker coverage angle as “the angular spread from on-axis (o dB) to the -6dB points on either side.”
What is speaker coverage pattern?
Ceiling speakers coverage is described as “conical” (cone shaped), with the volume loudest at the center. The stated coverage pattern describes the point the SPL drops to –6dB. This specification is listed as an angle in degrees, which describes how wide of an area the speaker will cover in sound.
What is dB in sound system?
Decibel Scale Sound is measured in units called decibels (dB). The higher the decibel level, the louder the noise. On the decibel scale, the level increase of 10 means that a sound is actually 10 times more intense, or powerful.
How do I calculate speaker wattage for room volume?
