The Carrboro Board of Aldermen met Tuesday night with officials from the Orange Water and Sewer Authority and the Home Builders Association of Orange and Durham Counties to discuss a proposed revision.
The law requires that all loud noises above certain specified levels are prohibited before 7 a.m. during the week and before noon on Sundays.
Alderman Diana McDuffee said the proposed revision calls for the noise ordinance to be extended to ban loud noises until 8 a.m.
"In order to limit the loud noises from construction, the proposed time will be between 7 a.m. to 8 a.m.," McDuffee said.
"But this proposal will only affect long-term projects that would be using loud machines like drills for a long period of time."
The loud noises are being produced by such construction equipment as earth movers, chain saws and jackhammers.
Mayor Mike Nelson, who lives near a site of construction, said the noises have been going on for a very long time.
"The noises go on week after week and month after month, and that's my concern," he said.
The proposed revision of the noise ordinance can probably be passed, but town attorney Michael Brough said he has just one problem with adjusting the ordinance.
