"Commercial purpose"
means and includes the use, operation, or maintenance of any sound-amplifying equipment for the purpose of advertising any business, goods, or services, or for the purpose of attracting the attention of the public to, or advertising for, or soliciting patronage or customers to or for, any performance, show, entertainment, exhibition, or event, or for the purpose of demonstrating any such sound equipment.
E. 
"Cycle"
means the complete sequence of values of a periodic quantity which occurs during a period.
