Sound Amplification Devices
The use of sound amplification devices in buildings, on the campus, or on any site of the University, whether owned by the University or under its control, is not allowed unless either a permit for the use is obtained or the use falls within an exception to the permit requirement. This policy applies to all University of Missouri employees, students, University affiliates, contractors, and visitors.
This policy complies with and implements Collected Rules and Regulations 110.040.
Expanded definitions and other information for this policy are available under Resources below.
“Sound amplification device” is defined as any electrically operated or non-electric assisted device for the amplification of sound. This includes but is not limited to:
- Public address systems, powered speakers, and music or voice amplifiers;
- Bull horns;
- Musical instruments.
Exceptions - Sound Amplification Devices Prohibited Without Permit
The use of sound amplification devices in University buildings or on any University grounds or site is prohibited unless any one the following three criteria are met:
1) The level of sound amplification meets all of the following requiremen
a. The amplified sound level does not exceed eighty-five (85) decibels when measured at a distance of fifty (50) feet or more from the sound source;
b. The amplified sound level does not exceed sixty (60) decibels when measured inside a classroom, library, or office, except that on days in which one or more colleges is conducting final examinations or has scheduled a reading day, the decibel level in this paragraph shall be forty (40) decibels;
c. The amplified sound level if played from a vehicle is not plainly audible at a distance of fifty (50) feet or more from the vehicle.
2) The use is part of and in furtherance of University-sponsored and scheduled activities, or the use is by University officials or employees in the performance of their duties.
3) A written permit approving such use is issued by MU Operations (882-7255), 305 Jesse Hall;
Notwithstanding any of the provisions of this policy, the use of sound amplification devices is prohibited if the use violates applicable federal, state, or local law or ordinances.
The following procedures assist with ensuring compliance with the above policy:
For the purpose of implementing and determining compliance with this policy, decibel levels are measured with devices approved by MU Operations. There are, however, devices, including smartphone applications, that can help discern excessive noise levels in the environment. In the absence of a noise level measurement, it is reasonable to expect a sound amplification device to fall within the exception to the permit requirement in the following circumstances:
(a) The amplified sound level is not plainly audible at a distance of one hundred (100) feet or more from the building, structure, or outdoor area in which the device is located when such device is being operated between the hours of 7:00 a.m. and 11:00 p.m. (On days in which one or more colleges is conducting final examinations or has scheduled a reading day, fifty (50) feet should be substituted for one hundred (100) feet);
(b) The amplified sound level is not plainly audible at a distance of fifty (50) feet or more from the building, structure, or outdoor area in which the device is located when such device is being operated during the hours of 11:00 p.m. to 7:00 a.m.
Written permits may not be issued for the use of sound amplification devices when one or more colleges are administering final examinations or has scheduled a reading day.
Written permits shall specify the time, duration, location, and manner for which the proposed use of a sound amplification device is authorized.
Any individual, department, or organization planning to use a sound amplification device in circumstances where uncertainty exists about whether the planned use will fall within the exception for non-disruptive sound levels is encouraged to apply for a written permit.
Complaints regarding amplified sound should be directed to the Office of the Vice Chancellor of Operations, 305 Jesse Hall, 882-7255. Upon receipt of a complaint about amplified sound, this office shall determine whether the use of the device or the amplification sound level complies with this policy.
If the use of the device or the amplification sound level does not comply with this policy or deviates from the permit purporting to authorize the use as to time, duration, location, or manner, the sound amplification shall be immediately brought into compliance with this policy and with any applicable permit.
If compliance with the policy or the permit is not forthcoming, any applicable permit shall be deemed to be revoked and the amplification may be turned off.
