Noise Spacing
Posted: Fri Aug 17, 2018 5:30 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.
