A spokesperson apologized for the noise and said the problem would be repaired on Tuesday.
"The community can expect a significant reduction in noise once repairs have commenced at this time," the company said in a statement.
When Action News stopped by the site just before 10 a.m. Tuesday, the sound was gone.
City officials say noise pollution violations are issued if they determine a difference in decibel levels greater than five between the property line and a close location where the sound cannot be heard.
"In this case, the levels were at least five decibels higher," a city spokesperson said.
