4.1.2.5 Evaluation of airplane noise of Shangrao Airport

1. Evaluation of airplane noise L_WECPN

(1) Evaluation of L_WECPN of sensitive points of Shangrao Airport such as school and hospital

According to forecast result in 2015 and 2020, the sensitive points listed in the table do not exceed the standard, in which the noise decibel value is highest in Cangbei Primary School, in 2020 their predictive value for 65.1dB, less than 70dB airport regional standard of the first zone.

(2) Comparison of 2015 (acceptance year) and 2020 (target year)

(i) Comparison of impact range under different sound levels

The prediction results show that 70-75dB noise impact area of Shangrao Airport in 2015 is 0.504km², 75-80dB area is 0.160km²; 70-75 noise impact area in 2020 is 0.897km², and 75-80dB area is 0.32km². It can be seen that as the airline business volume growth, different sound level of the noise influence to increase somewhat, but because of air traffic growth is not significant, so the noise scope of influence did not change much, to a target on 2020 Shangrao Airport surrounding sound better environmental conditions.

(ii) Impact of airport noise on adjacent villages

Houmentang of Shangrao Airport is location between Tashui Village, Zhoushi Village and Zhouwu Village, and the airport boundary is distributed with a plurality of natural village, the residents of relatively dense, on airport noise sensitive. This prediction in distance from the airport boundary nearest villages mainly includes Shanghuangwu, Xiawutang, Xujia of Tashui. Upon Forecast result and analysis, because of inhabitants of dispersive distribution, Xiawutang, Xujia of Tashui combination of scattered residents into the 70dBisoline range around the airport, on the whole the villages affected by the noise is small, no noise exceed the standard sensitive points.

(5) Evaluation conclusion

Shangrao Airport operation to forecast target year 2020, resident points have not entered into the range over 75dB. From 2015 to 2020, no buildings such as schools and hospitals have entered into 70dB; therefore, according to the LWECPN evaluation, airplane noise for people living near the airport can be endured.

2. Evaluation of airplane noise L_eq

(1) L_eq evaluation of sensitive points of Shangrao Airport such as schools and hospitals

According to forecast result of sensitive points such as schools and hospitals in 2020, in 14 sensitive points listed in the table, 13 sensitive points do not exceed the standard, in which the noise decibel value is highest in Cangbei Primary School, whose predicted value is 45.0dB at night in 2020, reaching the night noise standard of 45.0dB, because Cangbei Primary School does not carry out the teaching activity after 22 at night, and the school student accommodation, so the airport noise sensitive points in surrounding schools hospitals had no effect.

(2) L_eq evaluation of sensitive points of Shangrao Airport such as villages

According to forecast result of sensitive points of residents in 2020, Xiawutang, Xujia of Tashui diurnal have a total of 20 households L_eq predictive value than 55dB daytime noise standard; Xujia of Tashui, Beilong, Cangting, Shanghuangwu have a total of 217 households L_eq predictive value than 45dB night noise standard.

(3) Evaluation conclusion

Shangrao Airport operation to predict the target Day of 2020 have a total of 20 households night exceed the standard, 217 households have exceed the standard, thus, according to the Leq evaluation, Shangraoairplane noise for people living near the airport has caused certain effect.

4.1.3 Noise Impact Mitigation Mearsures

4.1.3.1 Measures to Reduce Noise Effect during the Construction Period

The Shangrao Airport Construction project comprises of airfield construction, terminal construction as well as other related support constructions. Noise prevention measures during the construction period should meet the following requirements:

Reasonably arrange the use of construction machines, reduce the use time of noisy equipments, improve repair and maintenance for all kinds of construction machines, try all means to reduce the noise emission of the construction machines, strictly limit the use of piling machine at night; In each phase of the construction period, in accordance with the noise effect characteristics of each construction machine and in combination of the situation of village distribution around the airport, reasonably arrange the use time of the construction machines, reduce the use time of highly noisy construction machines at night, and try to arrange daytime work for all kinds of constructions near Tashui Village and Huangwu Village both of which are close to the airport boundary.

During the structure construction period, build simple envelopes for concrete pumps and concrete tank trucks to reduce noise, improve repair and maintenance for concrete pumps, strengthen training and responsibility education for the construction personnel, and ensure stable operation of the vehicles.

4.1.3.2 Measures to Reduce Noise Effect during the Operation Period

To avoid airport noise effects on surrounding inhabitants, many countries in the world have stipulated land use rules related to airports. After the confirmation of the airport construction, it’s required to stipulate rules for using the surrounding land, legally determine land use limits according to its distance to the runway and the flight path. The rules should be followed by each party to avoid unnecessary disputes.

As the Shangrao Airport will have just a few flights, use comparatively less noisy airplanes of type B and C, and have few and scattered inhabitants around, the noise of airplanes will have no obvious impact on local inhabitants by 2020. To minimize the noise effect on the inhabitants, the follow measures are proposed:

Reasonable arrangement of land development around the airport is an important measure to avoid airplane noise interference; the local authority and government should make good planning for land use around the airport in view of future development of the airport, in accordance with the forecast results for the airport noise by the target year 2020 of this phase, implement planning control within an area 3-4km away from both ends and 0.5km away from both sides of the runway, and avoid constructing buildings which are sensitive to noises, such as buildings for inhabitants, science & research, cultural education and healthcare and office buildings. If such buildings are necessary, it’s required to take corresponding building sound-proofing measures. During the process of new rural construction, the local planning department should make reasonable planning for the settlements near the airport and provide space for the airport development.

This evaluation adopts Leq (equivalent continuous A-weighted sound pressure level) as the noise evaluation to forecast and analyze the noise impact on surroundings of the Shangrao Airport. The forecast and the Leq evaluation show a certain degree of sensitive point overproof around the airport. Therefore, this evaluation mainly proposes sound environment protection measures for the Leq forecast results.

(1) Determination of Noise Reducing Measures

In view of the requirements of WBG that the necessity of environmental protection oriented removal depends on whether there is any economical and feasible noise reducing measures. According to the environmental evaluation and analysis, with the L_eq proposed by WBG as the evaluation method, there are about 227 residential houses which will experience noise impact around the airport, but the overproof amount is less than 5dB, which shows a medium or small degree of noise impact, so it’s planned to use sound-proofing doors and windows with sealing measures for sound-proofing of the natural villages, so that both indoor and outdoor noises of such area can meet the corresponding noise standard requirements and also meet the residential requirements.

(2) Effect and Development of Sound-Proofing Measures

To make effective use of the land around the airport, sound-proofing measures can be taken for the transition area with L_eqd 45~51dB (A) around the airport to reduce the impact of airplane noise on the inhabitants. This is an internationally accepted way.

The sound-proofing effects of domestic professional sound-proofing windows show below in Table 6-1.

Table 6-1 Weighted Sound-Proofing Amount of Each Level of Sound-Proofing Windows

For buildings within the area with daytime equivalent A-weighted sound pressure level L_eqd 58~61dB(A) and night equivalent A-weighted sound pressure level L_eqd 48~51dB(A), level-IV sound-proofing windows (weighted sound-proofing amount: 35>R_W≥30) can be used to realize 25dB of the sound pressure level difference between indoor and outdoor;

At present, 30~35dB sound-proofing windows have been put on the market and have received good effect on traffic noise control. However, there is no successful experience in China in the aspect of airplane noise control for airports. According to the actual situation of the residential houses around Shangrao Airport, the sound-proofing measures proposed by this evaluation mainly consider the sound-proofing measures of doors and windows.

Domestic sound-proofing windows have various types including normal ones, natural draught ones and forced draught ones, the last of which is proposed for schools to meet the requirement on draught amount; general residents are proposed to use normal or natural draught sound-proofing windows.

(3) Expenses of Village Sound-Proofing Treatment Measures

It’s planned to use sound-proofing doors and windows with sealing measures for sound-proofing of the natural villages, so that both indoor and outdoor noises of such area can meet the corresponding noise standard requirements and also meet the residential requirements.

In view of social stability, this sound-proofing treatment plan will proceed with village as the unit. According to the evaluation impact scope, it will influence a total of 563 residential houses (comprising of 227 houses with noise impact), including 110 residential houses in Xiawutang and 71 in Shanghuangwu in Zhunqiao Township of Shangrao County, and 90 residential houses in Beilong and 230 in Cangting in Zaotou Town of Shangrao County, and 62 in Xujia in Tashui, Maojialing, Xinzhou District.

As counted by 2020, the door and window area of each house is 70m², with the unit price of windows of 500 yuan/m², so the calculated expenses for the sound-proofing measures will reach 19.95 million Yuan totally, with detailed evaluation results below in Table 6-2.

Table 6-2 Overview of Sound-Proofing Measures and Expenses for Each Natural Village in 2020

Sensitive Points	Residential Houses	Sound-Proofing Houses	Unit Price (10 thousand yuan)	Total Price (10 thousand yuan)
Xiawutang	110	110	3.5	385
Shanghuangwu	71	71	3.5	248.5
Beilong	90	90	3.5	315
Cangting	230	230	3.5	805
Tashuixujia	62	55	3.5	241.5
		7	7
Total	563	563	/	1995

(4) Expenses of School Sound-Proofing Measures

According to the forecast results, among altogether 14 schools within the noise evaluation scope, only the night noise of Cangbei Primary School reaches 45.0dB. However, as there are no teaching and studying activities in Cangbei Primary School after 22:00 and no students stay in the school at night, there is no need to take noise treatment measures for this school.

(5) Total Noise Expenses

As the Shangrao Airport project involves no environmental protection oriented removal at this phase and no measures are necessary for the overproof night noise in the school, the expenses of environmental protection measures at this phase only includes the fees for residential house sound-proofing measures, i.e. 19.95 million yuan in total.

(6) Noise Treatment Instructions

For the fact that Shangrao Airport meets the current noise evaluation indices and standard, but is overproof in inhabitant quantity and WBG proposed evaluation Leq as well as its standards, we think that many conditions have not been fully implemented, such as Chinese airport construction review program and conditions closely related to noise influence such as flight quantity, flight timetable and airfield operation situation. In addition, the current noise forecast results of Shangrao Airport are based on analogical data and airline operation parameters, so the airport operation will change as the related parameters are adjusted, which will lead to a great change in Leq forecast results. Therefore, we suggest that for the overproof noise forecast of Shangrao Airport, we solve future possible noise interference through a combination of operation period tracking and monitoring as well as supplemental noise calculation methods, detailed as follows:

① After the airport goes into operation, noise tracking and monitoring will be adopted for villages close to the airport and villages with overproof forecast. Generally speaking, the flights of airports divide into two seasons each year, so it’s required to monitor noises twice each year. Once it’s overproof, immediately use the preserved noise expenses to implement measures. As the flight quantity of Shangrao Airport will keep growing, it is suggested that we should implement noise measures step by step to reduce social influence.

② As noise monitoring can reflect noise effects only on the day of monitoring, the actual noise effects of the airport operation will change with comprehensive factors such as the weather. Therefore, after the airport goes into operation, the airport management department can entrust a related qualified organization to calculate each year’s daily noise effect based on the annual airport operation parameters and take the calculation results as the basis for noise effect analysis and feasible measures.
