As you may have heard, the recycling laws for NC bars have resulted in the separation of bottles and cans by bartenders while they are serving customers. On busy nights, they tend to become adept at tossing the bottles from a few feet away, in order to save time and attend to more people. The smaller the bar, the more likely it will be that bottles are getting smashed into other bottles in the bottle garbage can, since a larger bar would have a bar attendant to quietly dispose of the bottles, or have more containers for bottles set up closer to the bartender. (That's a world record for using the word "bottle" in a paragraph.)
Sound is created by pressure change in the air. The measurement of that change is in units called Hertz. Humans recognize sounds from 20 hertz to 20 Kilohertz. Breaking glass is at about 3 to 5 Kilohertz (3-5 thgousand hertz) and are probably amplified within the garbage can which would act as a megaphone cone. It is also preferable to the bar establishments that the glass bottles break within the can so that they can fit more into the outdoor recycling bin.Forcefully smashing bottles into a container that projects a loud sound and constantly elicits a fight-or-flight response from customers would not be considered the best way to run a bar in a world with common sense, but there are exceptions: say the music in the bar or nightclub is already really loud, as to exceed the sound of the breaking glass. But if the bar is relatively quiet, and you are smashing bottles into a container, you are wrecking your hearing, the hearing of whoever else is nearby, and you are doing something even stupider: you are making your customers uncomfortable and basically telling them to get the hell out of your bar which takes money out the door.
Now go break some more glass to try to exorcise you personal demons. Uga Booga!
Next: "Who is it?" "Hooker." "Go away."
