Figure 8 shows a balloon plot at 1 kHz in the far-field (10 m), while Figure 9 shows the directivity vs. frequency in the horizontal plane. Figure 10 shows the directivity vs. frequency in the vertical plane. These contour plots are used to determine the SPL’s uniformity in their respective planes.The results from the NFS can be used to satisfy the requirements of the “spinorama” test from CEA-2034. For PA applications requiring accurate phase information at high frequencies, the data from a high-resolution scan can be exported to EASE. The NFS can also be used to make single-point measurements in the nearfield that can be extrapolated into the far-field. This is useful for quick SPL checks when modifying crossovers or transducers, provided the type and the position of the loudspeaker does not change. The process requires correction curves generated from a full scan compared against a single-point measurement in the near-field.Holographic Measurement of the 3-D sound field using Near-Field Scanning provides the following benefits:• More information about the acoustical output (near-field and far-field)• Sound pressure at any point outside the scanning surface in the near- and far-fields (complete 3-D space)• Improved accuracy compared to conventional far-field measurements (coping with room reflections, microphone positioning, gear reflections, air temperature variations, etc.)• Higher angular resolution with less measurement points• Simplified handling (rotating the microphone instead of heavy loudspeakers)• Dispenses with an anechoic room and far-field measurements• Self-check capability by evaluating the fitting error• Comprehensive data set with low redundancy• Not a permanent installation• Considerably less expensive than an anechoic chamber.

These contour plots are used to determine the SPL ’s uniformity in their respective plane. The results from the NFS can be use to satisfy the requirements of the “ spinorama ” trial from CEA-2034. For PA applications requiring accurate phase information at gamey frequencies, the data from a high - resolution scan can be export to EASE. The NFS can also be used to make single - point measurement in the nearfield that can be extrapolated into the far - field. This is useful for quick SPL checks when modifying crossover or transducers, provided the type and the position of the loudspeaker does not change. The process requires correction curves generated from a entire scan compared against a single - distributor point measurement in the near - field. Holographic Measurement of the 3 - D sound discipline use Near - Field Scanning provides the following benefits:• More data about the acoustical output (near - field and far - field)• Sound pressure at any point outside the scan surface in the near- and far - fields (complete 3 - D space)• Improved accuracy compare to conventional far - plain measurements (coping with room reflections, microphone positioning, gear observation, air temperature variations, etc.)• Higher angular settlement with less measurement points• Simplified handling (rotating the microphone instead of heavy loudspeakers)• Dispenses with an anechoic room and far - playing field measurements• Self - check capability by evaluate the fitting error• Comprehensive data set with abject redundancy• Not a permanent installation• Considerably less expensive than an anechoic bedroom.
