Isn’t it amazing? This handbook was published 38 years ago by the EPA and yet the “mystery” of noise-caused negative reactions in ASD-Asperger diagnosed people not only continues, but is attributed to “defective development” of our brains.

The handbook is crammed with excellent info: Example, under Subjective Response:

What kind of mental or psychological effects can occur with excessive noise exposure?

Excessive noise exposure can bring about a wide variety of psychological responses or symptoms in the individual. A person may respond with anger, or experience symptoms such as anxiety, irritability, and/or general emotional stress. Noise may negatively affect work performance because of reduced worker morale and motivation. Distraction and poor judgment may result from mental fatigue. (14)*


What physiological changes occur in response to noise?

Loud sounds can cause an arousal response in which a series of reactions occur in the body. Adrenalin is released into the bloodstream; heart rate, blood pressure, and respiration tend to increase; gastrointestinal motility is inhibited; peripheral blood vessels constrict; and muscles tense. On the conscious level we are alerted and prepared to take action. Even though noise may have no relationship to danger, the body will respond automatically to noise as a warning signal. (14)

  1. So: one wonders? It seems that the only area of appropriate sensitivity – if one isjudged to be a social inferior/ lesser being / not-fully-human- one is to have is to discern the fleeting momentary whims of ones’ (self-styled) betters.

    One is to be ‘numb’ (dumb?) to all else, or so it seems.

    (Foolish Normies! If you want results, then facilitate the process and stay out of the way!) On second thought – maybe they’re not interested in results -perhaps they just want to ‘dominate’ (feel the intoxication of power, perhaps? Tread on our upturned faces?) and control us – as if ***power for its own sake*** is THE end?
