    What is an acceptable decibel level?

    I have a recreational use (haunted attraction) that is coming up for an amendment to their special permit to extend their hours. What have used as an acceptable decible level at the property line for these types of uses?

    What kinds of contingencies have you attached to these uses?

    It's a political knightmare for me. lol

    Also: this is an AG area that is now surrounded by urban residential on two sides.What is a typical distance between this type of use and urban residential?

    What are your current db levels for ag and residential ?
    Are there time limits on/for any range of db on them ? like after 10 pm the db acceptable level drops to x ?
    How often / How hard do you enforce db levels ?

    Why don't you knock it off with them negative waves?
    Why don't you dig how beautiful it is out here?
    Why don't you say something righteous and hopeful for a change?

    Are you sure you're not hurt ?
    No. Just some parts wake up faster than others.
    Broke parts take a little longer, though.

    We don't have decible levels set for any uses but this use has one attached through the special permit. I believe it's 80 or 90 decibles.

    I believe the only noise complaints we've had are at this use. We measured the levels with a sound meter once or twice. We have a heavy complainer in the adjacent neighborhood.

    ETA: I'm in the county.

    80 to 90 dBA is pretty loud. Might I suggest 55 dBA at night and 60 during the day. You might also consider that if the area is urbanizing, it might not be appropriate to extend the hours.

    Does your ordinance/regulations specify a noise level? Or do you have municipal codes that specify noise levels? I'd love to get some regs to point to for my recommendation. Thanks!

    Our code states that at property lines, dBA shall not exceed 70 between 7 am and 10 pm, and not to exceed 65 dBA between 10 pm and 7 am.

    Wow that is pretty loud. From what I found over the last week, residential areas are generally aroun 55 during the day and 45 at night. I am recommending noise limitations for this use around 50 after 10pm. We'll see what the PC and county board thinks about that. They actually really dislike this user. He's surrounded on three sides by urban residential. Hopefully my recommendation isn't totally off base.

    I've found this to be an invaluable resource:

    simmer down, now...

    for our amusement permit section:

    14-6. Regulation of noise.
    An applicant for a special amusement permit hereunder shall, as part of his/her application, demonstrate his/her ability to prevent the emanation of excessive noise from the premises sought to be licensed brought about by music, dancing or entertainment, except for a radio or other mechanical device excluded under 28-A M.R.S.A. *1054 or amendments thereto. The performance of amplified music out of doors by licensees is categorically declared to be in violation of this article.
    A. Sources of noise. Sources of noise contemplated by this section shall include musical instruments, sound modification or amplification devices used in connection with musical instruments and/or other similar devices which produce, reproduce or amplify sound created by musical instruments. Sources of noise shall further include any noise or sound produced directly or indirectly by the applicant's music, dancing or entertainment except for those mechanical devices specifically excluded under 28-A M.R.S.A. *1054 or amendments thereto.
    B. Noise. Sources of noise shall be required to be muffled so as not to be objectionable due to intermittence, beat, frequency, shrillness, intensity or volume.
    C. Noise control. The maximum permissible sound-pressure level of any continuous, regular, frequent, intermittent or periodic source of noise produced by any activity regulated by this article shall not exceed 71 dB(A) at any time at the measuring locations specified in *14-6D(3)(e) below.
    D. Measurement procedures. For the purpose of determining noise levels as set forth in this article, the following procedures shall be used:
    (1) All personnel conducting sound measurements shall be trained in the current techniques and principles of sound-measuring equipment and instrumentation.
    (2) Instruments used to determine sound-level measurements shall conform to the standards of ASI Type I or Type II meters.
    (3) The general steps listed below shall be followed when preparing to take sound-level measurements:
    (a) The instrument manufacturer's specific instructions for the preparation and use of the instrument shall be followed.
    (b) The sound-level meter shall be calibrated before and after each set of measurements. The calibrator itself shall be recalibrated at least once every year.
    (c) When measurements are taken out of doors, a wind screen shall be placed over the microphone of the sound-level meter as per the manufacturer's instructions. No sound-level measurement shall be taken at wind speeds greater than 12 miles per hour; neither shall measurements be taken during periods of precipitation.
    (d) The sound-level meter shall be placed as specified by the manufacturer's instructions and at least four feet above the ground. It shall be placed so as not to be interfered with by individuals conducting the measurements.
    (e) Measurements shall be taken at points outside the licensed premises which are no less than five feet and no more than 10 feet from the lot lines of the licensed premises.
    (f) No less than two readings taken by the sound-level meter within a fifteen-minute period shall constitute a reasonable basis for averaging a set of measurements. A simple arithmetic average may be taken, summing all the measurements and dividing the sum by the number of measurements taken. This is known as "L50 descriptor," representing the mean sound-pressure level which is exceeded 50% of the time.
    14-7. Loud and unreasonable noise.
    Regardless of whether or not the mean sound-pressure level limit as set forth in *14-6C is exceeded, the licensee or his/her authorized representative shall not permit the use of the premises to result in any continued, excessive or loud and unreasonable noise or any noise which either annoys, disturbs, injures or endangers the comfort, repose, health or safety of individuals or which results in disturbing the peace and tranquility of the neighborhood.

    and this is our noise ordinance:

    Chapter 139, NOISE

    Don't use db in setting a noise level. Background traffic, noise, wind through trees, crickets, etc. will exceed 65 to 70 db. In some cases the actual use will mask the background noise resulting in a lower db. Say you set a 50 db limit on the use and you happen to go out one night and a get a 60 db level on the use but the background is 65 db. What you do then?

    Best thing you can do is leave it to the cops to enforce their disturbing the peace laws. If you approved the use you approved the noise. Don't like the noise, don't approve the use.
