Noise that distresses is an ASSAULT What is Sound -- and what is NOISE? Sound is a form of energy that is transmitted by pressure variations which the human ear can detect. When one plays a musical instrument, say a guitar, the vibrating chords set air particles into vibration and generate pressure waves in the air. A person nearby may then hear the sound of the guitar when the pressure waves are perceived by the ear. Sound can also travel through other media, such as water or steel. Apart from musical instruments, sound can be produced by many other sources - man's vocal cord, a running engine, a vibrating loudspeaker diaphragm, an operating machine tool, and so on. Noise is any unwanted sound. Noise perception is subjective. Factors such as the magnitude, characteristics, duration, and time of occurrence may affect one's subjective impression of the noise. NOISE  is ASSAULTIVE!   Because Noise is invisible it is not treated with anywhere near the seriousness increasingly necessary for the protection of human health. Health authorities everywhere are becoming more aware of this scourge of modern-day living, however the public MUST demand legislative changes that truly reflect the gravity of the matter.
