Noise Spacing

Postby Enfaded! » Fri Aug 17, 2018 6:30 pm

Hey folks ;

Noise is a major factor in being detected during operations. Our Environment is constantly subject to a constant background noise , in general circumstances for ops this may be anywhere from 30 dB to 80 dB in varying scenarios. The higher a background noise level is the less receptive sensitive receivers will be to “instrusive noise “ this is noise experienced for short bursts above existing background noise levels. For example the sound of a large Diesel truck engine breaking in a street area , or a piece of steel or frame of some other structure fracturing under stress with a background noise or industry element.

I think whenever we do ops and are forced to conduct noise procedures it’s important to carry them out relative to the existing background noise level. For example a noisy entry to a premise may be masked by a train passing by or a series of vehicles. Alternatively a quiet area with a extremely low background noise level may prove challenging. Maybe you might be carrying out a activity with high levels of noise production such as cutting / sawing at 2:00am in a extremely quiet area, in this regard I have found “noise spacing “ is essential , having small burst of noise inter dispersed over 7-12 minutes breaks can prevent sleeping persons or semi non viligant persons to not detect noise abnormalies.

Please feel welcome to discuss this and share your personal experiences and thoughts in relation to ops and your noise management techniques.

I often use sound masking on ops; using passing traffic, wind through trees and other sonic disturbances to cover the sound of my own activities. However, on very quiet nights where I need to make some noise I just space out my actions so they're less likely to draw attention. Ever been lying awake at night and suddenly hear a creak or snap somewhere in the house? You sit bolt upright and listen in for anything else - if you hear another noise you may investigate, but after a few seconds if all is quiet you'll let your guard down again. If I need to hop a metal fence, for example, I'll jump onto it in a cat leap (hands holding the top, feet supported in the middle) and just hang there for a while. After 30 seconds or so, I'll throw myself over the fence and hide, listening again for any sound of activity or faces appearing in windows. Sometimes noise is unavoidable, so you need to find ways of disguising or timing the sounds you make so they'll be less conspicuous.

Normally, I adjust how much noise I make according to the ambient noise, I don’t really use anything in particular to mask any noise, like passing traffic, but I might start using such techniques in future when it comes to inevitable noise.

Using envoriment sounds can help a lot, you can also create your own to direct attention away from your location. I agree that timing intervals between the noises are crucial yet it requires practice and patience. If you're using tools you can try to muffle the noise. I was thinking in getting some flexible rubber to put on some of my metal tools like the grappling hook. The sound will be more of a base thud than a sharp clinging one if it hits a hard surface.

That's actually a good idea. The rubber coating may even provide a better purchase on smoother surfaces, although will probably wear away rather quickly.

Exactly, you have to feel the type of rubber before though to get a physical impression, some provide more grip than others. The extra grip can certainly make things go more smoothly and maybe less stressfull when it comes to noise reduction.
