What is a noise abatement procedure?

Defining noise abatement procedures that avoid residential areas as far as possible and avoid over-flying sensitive sites such as hospitals and schools. Using continuous descent approaches and departure noise abatement techniques. Applying different operational charges based on the noisiness of the aircraft.

What is a noise abatement departure?

Every major airport has Noise Abatement Procedures (NAPs), which are procedures designed to reduce the impact of aircraft noise on the community. Noise Abatement Departure Procedures (NADP) such as directing aircraft to depart over water at night.

What is NADP 1 and 2?

They are called “NADP 1” and “NADP 2” (Noise Abatement Departure Procedure). 1 is used where there are noise sensitive areas close to the airport and 2 is used to alleviate noise in an area further away, say 25 kms+ from the start of roll on the airport runway.

Where are noise abatement procedures found?

Noise Standards — Noise abatement procedures basically start from the need to meet ICAO standards in what are known as “chapters” from ICAO Annex 16, Vol I and that filters down to individual countries. In the United States they are contained in 14 CFR 36 to become “stages.”

What are the various methods of noise control?

What federal aviation regulations are concerned with the aircraft and airport noise issues?

The Federal Aviation Administration (FAA) issued Title 14 Code of Federal Regulations (CFR) Part 150, Airport Noise Compatibility Planning, in January 1985. 14 CFR Part 150 provides airport operators with a formal process for addressing airport noise and noncompatible land uses.

What is an acceptable noise level in residential area UK?

Permitted noise levels The permitted noise level using A-weighted decibels (the unit environmental noise is usually measured in) is: 34 dBA (decibels adjusted) if the underlying level of noise is no more than 24 dBA. 10 dBA above the underlying level of noise if this is more than 24 dBA.

How can I reduce my FCU sound?

Tactics for reducing HVAC noise in an open office environment

1. Choose a quieter type of HVAC equipment.
2. Carefully choose locations & operation of fans and air handlers.
3. Add sound boots.
4. Make quiet areas more comfortable.
5. Improve acoustics with sound absorbing materials.

What is the most effective noise control method?

Elimination. Elimination is a process that eradicates the noise source it is the most effective way to prevent risks to workers and should always be considered when introducing a new work process, selecting new work equipment and designing the layout of the workstations.
