I live on Big Island, Hilo side, and struggling with noise issues is something I struggle with a great deal. If you know of anyone on the Big Island, preferably Hilo side, that I could get together with to start making more progress on lessening unwanted noise here, please help me get in touch with them.
p.s. I had to select a neighborhood on Oahu above, but I do not live on Oahu.

We've updated our website on this page Reporting Noise Violations to provide a link to the Big Island Noise Reference Manual. This manual, although dated 2008, is still a pretty good reference. One of the biggest obstacles folks encounter in dealing with noise is first determining WHO has jurisdiction over the noise. The manual addresses jurisdiction fairly well. Generally, there are noises that fall under the Hawai'i Department of Health state-wide, their "updated" contact info is on the same page above, your city and county police department, in your case Hawai'i Police Department, and the SPCA for barking dogs and other animal noises. For those noises dealing with loud vehicles there are several statutes cited on the page above that can be referenced when discussing with HPD. Those that are "ROH" are Revised Ordinances of Honolulu and wouldn't apply to City and County of Hawai'i, but those marked "HRS" are Hawai'i Revised Statutes and apply state-wide. A more descriptive list of the laws/statutes can be found on our page here: Hawai'i Noise Laws.
But whether the jurisdiction of HPD, Department of Health, or whomever, the first thing you can do is pick up the phone and call or drop them an email to report the offender of the problem.
We also recommend contacting your Hilo-side council member, which is probably either District 1, 2, or 3. All cover some portion of Hilo. District 1 council member is Valerie Poindexter, her email is: vpoindexter@co.hawaii.hi.us, District 2 would be J Yoshimoto, his email is: jyoshimoto@co.hawaii.hi.us, and finally, District 3 is Dennis Onishi, his email is: donnish@co.hawaii.hi.us. All of your council members' contact info can be found at: http://www.hawaiicounty.gov/council/. Never hesitate to let your council people know what's on your mind.
Good luck,
