MUIC & ACOUTIC – LIVE OUND & PA YTEM CALCULATOR
Pa Array Pattern
A precise tool.
What is the Pa Array Pattern & How does it work?
Line array systems are widely used in live sound applications due to their ability to provide consistent coverage over large distances. The splay angle of a line array is crucial for determining the audience depth where the sound remains coherent and free from comb filtering.
The splay angle, (theta_s), is defined as the angle between two adjacent elements in the array. It affects how far back the system can project a uniform sound field. The formula to calculate the maximum audience depth (D) for a given splay angle is:
D = frac{lambda}{2 sin(theta_s / 2)} times N
var = meaning
D = Audience Depth
(lambda) = Wavelength of sound
(theta_s) = Splay angle in radians
N = Number of elements in the array
D = Audience Depth
(lambda) = Wavelength of sound
(theta_s) = Splay angle in radians
N = Number of elements in the array

Frequently Asked Questions
What is the splay angle in a line array?
The splay angle is the angle between two adjacent elements in a line array, affecting sound projection distance.
How does splay angle affect audience depth?
A smaller splay angle increases the maximum audience depth where the sound remains coherent and free from comb filtering.
Can you explain comb filtering in line arrays?
Comb filtering occurs when sound waves interfere constructively or destructively, causing peaks and troughs in the frequency response.
What is the formula for calculating maximum audience depth?
The formula involves the splay angle, wavelength of sound, and spacing between array elements.
How do I determine the optimal splay angle for my setup?
Consider the desired audience depth, room acoustics, and the specific requirements of your live sound application.
What are the benefits of using a line array system in live sound?
Line arrays provide consistent coverage over large distances, reducing comb filtering and improving overall sound quality.
Can you give an example of how to use this calculator?
Input the splay angle, wavelength, and spacing between elements to find the maximum audience depth for your line array setup.
