Considering Statutory Nuisance Department of Environment Transport Regions Advice There is no set level at which noise becomes a Statutory Nuisance. Noise is generally regarded as unwanted sound, it could be too loud, too intrusive or just happen at the wrong time or without warning . Sound is measured in decibels the World Health Organisation states 45-50dBL is loud. But VOLUME is not the only thing that can affect the our response to sound. It could be long periods of noise above the normal background noise levels or our homes, i.e. television conversation. Regular repetitive noise affecting concentration, the enjoyment of your home and garden can have serious mental health issues, causing personality disorders, causing the victim to make irrational decisions that would not be made under normal circumstances, anxiety and anger amongst other emotions. This is where we believe that the Propane Gas Gun (the so called Bird Scarer) is top of the nuisance list. When used intensely it can cause a mental attitude that steers the brain into anticipating the next shot/explosion, thus taking over a normal way of life. Reaching conclusions on these matters does test the person responsible for investigating complaints made about these devices, as intermittant monitoring by very experienced officers cannot ascertain the realistic affects on victims suffering from this noise pollution/abuse. Professional mediation should be considered.
