Fortunately, speech remains intelligible even when the low-frequency cut-off is raised above 300 Hz. If you dont like either black or white, then go for this superb-looking silver-colored microphone. The range comparisons provided below are based on what I call the general scenario, which assumes that we want to pick-up human voice at a normal conversational volume (with an SPL of 70 dBA at 1 foot) in a reasonably quiet indoor environment (35 dBA broadband). Qty. On the other hand, substantial ranges are possible with a reasonably-sized device when capturing human voice. When L=l, then for Running wave microphone: where S aperture area, l- sound wavelength. If all of the ambient noise happens to be coming from the same direction as the sound were trying to capture, then theres really no way to reduce it (well, if were really lucky, the noise will be limited to a narrow range of frequencies that we can filter-out without affecting the signal fidelity, but thats rarely the case). The inverse-square law doesnt apply at distances less than a wavelength or so from a sound-source, but thats obviously not relevant to a long-range scenario. Take a look at some of the most popular and trending products. Directivity is the most important attribute in a long-range microphone, but high gain can also help.
