The Signal-to-Interference-plus-Noise Ratio (SINR), Propagation loss and the inverse-square law, Ambient noise typically dominates total noise when picking-up sound at long ranges, Putting it all together: estimating the range of an ordinary microphone, The keys to increased microphone range: directivity and gain, Reducing the effects of ambient noise via directivity, Reducing the effects of self-noise via acoustic gain, Including microphone directivity and gain in the SINR equation, The catch: directivity and gain are usually frequency-dependent, Shotgun microphones (and line microphones in general). All other things being equal, range scales approximately with the dish diameter. 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. When the distance is about 100m, sound pressure drops more than 40dB(compared to a distance equal to 1m). Night Owl Security Surveillance Microphone, 11. CS180-4K Long Range.

Ditched the Shack mike. The directivity of an array microphone depends on the product of the number of elements and the element spacing in wavelengths. So the sound pressure of the sum of the ambient noise and self-noise isnt equal to the sum of the pressures, but rather to the Root-Sum-Squared (RSS) of the pressures: Ntotal = sqrt(I2 + N2). The diagram shows that when G=15dB(value for a good microphone), the distance is three times bigger than the ear. Pros & Benefits: It converts a listening area of 375 sq ft to 35 sq meter; . Directivity is the most important attribute in a long-range microphone, but high gain can also help. The Long - Range Laser Listening Device (Laser Microphone) is a highly sophisticated surveillance apparatus that utilizes an invisible infrared laser beam to eavesdrop on a target. But how do such long-range microphones workand how well do they work? I would like to add a very directional mic to my H-A input in place of the normal mics.

Instead, the only way to significantly increase the pick-up range in a typical scenario is to reduce the ambient noise, andafter weve reduced it sufficiently that self-noise becomes an issueto optionally reduce the effects of self-noise. But the main advantage is that this method allows the construction of small-sized directional microphones. For example, if an SPL value uses A-weighting, which we can write as dBA, then the corresponding absolute pressure found using the formulas above would also be A-weighted. Using this ideology, microphones can be compared with the human ear. But in long-range microphones, the directivity can be high enough to knock-down the ambient noise level to the point where the self-noise rivals it.
