Re: "..."BOOM!! BOOM!! BOOM!!"
Those seeking a large profit margin on their corporate investments should start now investing in corporations which manufacture 'hearing aids'.
The bass sounds from the lower sonic spectrum that make up these "disturbances of the peace" when mongrels ride around blasting their car stereo systems, travel much slower over distance than do mid-range and treble frequencies.
Bass and sub-sonic bass frequencies actually penetrate and pass through solid objects, including concrete and human bodies.
As such they are capable of producing far more damage to the human inner ear anatomy, which is comprised of tiny micro-bones which transmit the sound vibrations from the tympanic membrane (eardrum).
Sound at high volume alone causes 'temporary threshold shift' (the phenomenon experienced by rock concert audiences...ringing in the ears [tinnitus] and an inability to understand normal speech without increasing the volume).
However, when the volume is primarily from the lower sound spectrum, as is rap noise, far greater damage and permanent hearing loss occur with each repeated exposure, and the damage is cumulative.
So, my friends, invest in the hearing aid technology industry, because millions of stupid morons will soon be spending large amounts of their income there.
