Acoustic Considerations The 503BG maximizes performance in close-talking applications through its tailored frequency response, directionality and distance discrimination. It optimizes and controls sounds within the 100 to 7000 Hz frequency range and reduces sounds outside that range. The BG503 rejects noise through its inherent directional properties and discriminates against distant sounds in favor of close-range sounds.

OVERALL DIMENSIONS FIGURE 3 Operation For best performance, speak as close to the 503BG as comfort permits. A distance of 1 to 5 cm (0.4 to 2 inches) provides the greatest discriminations between voice and background noise.
