적용 범위

This standard applies to areas around airports affected by noise generated by passing aircraft. It is specifically designed for environmental noise control in residential and educational zones near airports. Local governments are responsible for designating the specific geographical boundaries of these applicable zones. It references GB 9661 for measurement methodologies.

기술 요구 사항

The standard establishes the environmental noise limits for areas surrounding airports using the Weighted Equivalent Continuous Perceived Noise Level (LwEcPN) over a 24-hour period as the primary evaluation metric. It categorizes the affected areas into two distinct zones with specific noise limit requirements. Compliance with these noise limits is mandatory for airport operations and surrounding urban planning. The standard defines Class I areas (special residential, general residential, and educational zones) and Class II areas (other living areas not covered in Class I).

시험 방법

The standard specifies that the permissible noise levels are measured outdoors in flat, open areas. The measurement setup requires the microphone to be positioned 1.2 meters above the ground and at least 1.0 meter away from any reflecting surfaces. All measurement procedures, calculation methods, and instrument specifications must strictly follow the guidelines outlined in GB 9661.

자주 묻는 질문

What operations are regulated under GB 9660-88?

GB 9660-88 regulates the environmental noise generated by aircraft operations around airports, specifically targeting the impact on surrounding residential and educational areas.

What is the evaluation metric used in GB 9660-88?

The standard uses the Weighted Equivalent Continuous Perceived Noise Level (LwEcPN) measured in decibels (dB) over a 24-hour period to evaluate aircraft noise.

How are the applicable zones determined under this standard?

The specific geographical boundaries of the applicable zones are designated by the local People's Government. They are generally divided into Class I and Class II areas based on land use.
