<p>Environmental noise should always strike the electroencephalograher as strange, due to its fast, rhythmic appearance. When an electrical system is not grounded, when there is poor connectivity between devices, when there is “electro-smog” in the environment,
    as we sometimes see in large cities, these are all situations where environmental noise such as this appears. Its best to check a building for environmental noise before moving in, as sometimes the solution is difficult to arrive at.</p>
