FAA Noise Compatibility Program
Cleveland Hopkins International Airport (CLE) established a Noise Compatibility Program to relieve the impact of air service on the local communities. Demonstrating the airport’s commitment to its neighbors’ quality of life, this program has been active for well over two decades.
Cleveland Hopkins has favorably responded to community suggestions and the Federal Aviation Administration’s (FAA) Part 150 Record of Approval by instituting sustainable measures such as: Residential Sound Insulation Program; Noise Monitoring Stations; Aircraft Noise Reports; Noise Hotline; Runway Closure Notice; Aircraft Run-up Policy; and Home Acquisition. In addition a Noise Glossary and question and answer section is located on this page to help you better understand airport operations and noise program terminology.
Residential Sound Insulation Program
Since 1996, acoustical windows and doors have been installed in neighboring properties, to buffer aircraft noise. Although the modifications do not soundproof, they improve the quality of life for the area residents at no cost to the homeowner.
Area residents can contact RSIP Customer Service at (216) 265-6004 to determine eligibility. Eligible homeowners can request a RSIP application and brochure or download an application.
Visit the RSIP website to learn more about the program purpose and status, eligibility, selection protocol, benefits, aviation easement, products installed, acoustical testing, funding sources, property assessments, process, construction activities, a question and answer section and a glossary.
Noise Monitoring Stations
Noise monitoring stations record aircraft sound levels. There are eleven permanent sites located in Cleveland, Brook Park, Olmsted Township, Olmsted Falls, and Berea. The placement identifies the impact of noise on most surrounding communities. Each site measures aircraft noise 24 hours a day, 7 days a week and transmits data for recurring analysis. The equipment is automatically calibrated daily and manually adjusted twice a year to ensure accuracy. A map of each location is available below in Adobe Acrobat (PDF) format.

Aircraft Noise Reports
The Noise Compatibility Officer compiles data and publishes quarterly and year-end reports of all aircraft noise activities. Statistics are available below in Adobe Acrobat (PDF) format. Click on the year and quarter you are interested in to open the associated PDF file.
Noise Hotline
A dedicated hotline is available to record aircraft noise complaints. Please provide the date and time of the unusual aircraft occurrence(s) and your contact information, i.e., name, address, and telephone number. A knowledgeable Noise Compatibility Officer is on staff to register, evaluate, and return incoming calls by the next business day.

Runway Closure Notice
Construction at the airport can have a significant impact on how it operates and where aircraft are directed. When one or more of the runways are closed, more operations will be pushed to the open runways, which inevitably changes aircraft flying patterns.
The runway closure notice is designed to assist residents in determining when to expect changes to our normal runway operations due to major construction projects. The notice references projects that are deemed significant or under construction exceeding a week. This published map is for informational purposes only. It should not be interpreted as an official Notice to Airmen (NOTAM) or Field Condition Report.
Click on the image below to view runways where construction is currently ongoing, or planned for the near future. You can download a copy of the map in Adobe Acrobat (PDF) format.
Aircraft Engine Run-up Policy
All aircraft owners and operators are required to notify airport operations when testing engines within the designated timeframe. Operational guidelines have been established to maintain compliance with the aircraft engine run-up policy.
Home Acquisition
The City of Cleveland, Department of Port Control established a Home Acquisition Program to operate under Cleveland Hopkins International Airport. It has implemented two large acquisition projects since the 1980's: The Airport Acquisition Program (North) and the Brook Park Home Acquisition Program.
Properties qualify to participation in the Acquisition Program for two main reasons: 1) properties are situated in a high noise impacted area; 2) and/or the land is required for Airport expansion. All acquisition projects are regulated by the rules and regulations of the Federal Uniform Relocation Act.
Airport Acquisition Program (North)
In 1984, the Airport began acquisition of properties within the City of Cleveland and North of the Airport. Using partial federal funding, 450 residential property owners received relocation assistance and qualifying benefits. The area has since been redeveloped into the Cleveland Business Park, including businesses such as Sysco Food Services, Boise Cascade Office Products and the Airport Rental Car Facility.
Brook Park Home Acquisition Program
The Brook Park Home Acquisition Program was established as part of the 2001 IX Center Settlement Agreement. This Agreement created a working partnership between the cities of Cleveland and Brook Park. Besides making a home acquisition provision, the transfer of ownership of the IX Center and other long-term Airport expansion opportunities were also included.

Calibration |
|
The adjustment of a sound or vibration measurement system so that it agrees with a known reference sound or vibration source. Calibration is performed before each set of measurements. |
|
|
|
|
|
Day-Night Equivalent Sound Level (DNL or Ldn) |
|
A noise measurement used to describe the logarithmic time average of aircraft noise decibel levels over a 24-hour period. Every second of the day is included, so increasing the amount of time without any aircraft noise will decrease the DNL. In addition, DNL weighs aircraft operations that occur between the hours of 10:00 p.m. and 7:00 a.m. an additional 10 decibels to account for increased annoyance. DNL may be determined for individual locations or expressed contours. DNL is currently the accepted measurement for aircraft noise analysis. |

Decibel (dB) |
|
A unit of relative loudness. The smallest amount of change that can be detected by the human ear is one decibel. The decibel uses a logarithmic scale to cover the very large range of sound pressures that can be heard by the human ear. A 20-decibel sound is 10 times as loud in terms of energy content as a 10-decibel sound; a 30-decibel sound is 100 times as loud. |
|
|
|
|
|
Equivalent Level (Leq) |
|
The equivalent level expresses the actual fluctuating noise levels existing over a stated period of time in terms of a steady-state noise level over a similar time period that has the content of energy as the fluctuating levels. |
|
|
|
|
|
Maximum Noise Level (Lmax) |
|
The maximum noise level, in decibels, (dB), is the maximum value of the noise that occurs during a single event, such as an aircraft flyby. |
|
|
|
|
|
Noise Event |
|
A noise event is the measured sound produced by a single source of noise over a particular period of time. An aircraft noise event begins when the sound level of an over flight exceeds a noise threshold and ends when the level drops down below that threshold. |
|

Stage 2 and Stage 3 Aircraft |
|
Commercial jet engines currently meet either Stage 2 or Stage 3 noise standards. Stage 2 engines are older and noisier than Stage 3 engines. Stage 3 aircraft incorporate the latest technology for suppressing jet-engine noise and, in general, are 10dB quieter than Stage 2 aircraft. This represents a halving of perceived noise; however, actual noise reduction varies by aircraft. All aircraft greater than 75,000 lbs had to meet State 3 noise standards as of January 1, 2ooo. |

|
|
|
Hush Kit |
|
A hush kit is a device for reducing noise from an engine; most commonly the term refers to devices which reduce noise emissions from low-bypass turbofan engines, as fitted to older commercial aircraft. Hush-kitted Stage III aircraft are previously Stage II aircraft that have been adapted to meet State III requirements. |
