(5)
Excessive sound or noise means sound occurring in the environment that is annoying, disturbing or harmful.
(6)
L50 sound level means the sound level exceeded fifty (50) percent of the time, based on any measurement period of not less than ten (10) minutes.
(7)
Person means any natural person, individual, owner, operator, public or private corporation, firm, association, joint venture, partnership, municipality, governmental agency, political subdivision, public officer, responsible party or any other entity whatsoever or any combination thereof, of whatever kind.
