Loudspeaker Frequency Response and Polar Patterns
{"Image DocumentName": "Loudspeaker Frequency Response and Polar Patterns", "Image ImageDescription": "Dispersions at different frequencies. Listener position. Polar plots map performance. As with directional microphones, a loudspeaker s overall frequency response will be best on-axis, directly in front of the loudspeaker. As you move off-axis with a loudspeaker, not only will the sound be reduced, but the frequency response will change as well. A loudspeaker with specifications showing a nominal 90 degree by 40-degree dispersion (coverage) pattern only holds that pattern over a limited frequency range. Lower frequencies will spread out in a more omnidirectional fashion due to their much longer wavelengths. Very large devices are required to control the dispersion pattern at the lower frequencies.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
