A work-around to this limitation, which almost all modern shotgun microphones use, is to combine the shotgun microphones interference tube with a conventional hypercardioid microphone configuration; the hypercardioid provides modest directivity at low frequencies, while the interference tube provides high directivity at higher frequencies. We may earn a commission if you click on a link, but at no extra cost to you. On the other hand, arrays can be extremely practical in applications that can do without either high directivity or wide bandwith: If limited bandwidth and a low-frequency roll-off can be tolerated, then a modest but useful directivity of four (6 dB) can be achieved with just a two-element array. Thanks to the televised sporting events (primarily American football), the parabolic microphone is the type of microphone most commonly associated with very long ranges.

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).
