This study investigates individual noise sensitivity to change in aircraft noise levels for residents living near Fukuoka airport, which has proposed a capacity expansion plan. To understand better peoples' perception of aircraft noise, the authors introduced a reference point (RP) concept into analysis of noise sensitivity. A field survey consisti...

... An adverse effect is the sensitivity hearing loss, regarding to the aircraft noise level variations. According to Phun et al. [20], the longer the people are exposed to noise, the less is its ability to notice the increased intensity. ...
This study compares metrics for environmental noise diagnosis in schools at airport vicinity. The goal is to analyze and identify the most suitable criteria for scaling aircraft noise impact over schools, during landing and take-off operations. A Brazilian case study is conducted, based on the noise mapping and sound level verification. The day-night average noise level (DNL) and the time above limit (TA) are investigated using acoustic simulation and noise mapping and in order to identify the critical receivers. Results of DNL and TA for two schools at airport surroundings show that the criteria adopted by the municipal and airport authorities to describe the airport noise are unsatisfactory and do not reflect the intermittent behavior of this type of noise. It was verified that individual receiver analysis, based on noise interruptions thought TA parameter is more suitable for evaluation of noise impact over schools at airport vicinity.
... Headphone interview system was firstly developed by Phun et al. (2013) to study the aircraft noise sensitivity for Fukuoka airport-residents. The system allowed to assess the individual noise sensitivity to variation of aircraft noise levels as well as to assess the perceived indoor noise levels inside each dwelling. ...
This paper examines the effects of other people’s noise-situations on an individual’s maximum acceptable flight frequency (MAFF). Two scenarios for interview questionnaires: with and without additional noise information were established under a hypothetical setting. Two MAFF models, one that tests for effect of available noise information and another testing for effect of other people living in different noise-affected zones, were estimated using data from a pilot survey based on a developed headphone interview system. Results of the first model indicated a significant effect of the available noise information on MAFF. From the second model, it was found that MAFF would increase if subjects took into account the noise-situations of people living in the high noise-affected zone, all else being held constant. For those located in the moderate noise-affected zone, the results suggest a reduction in MAFF. There was an increase in MAFF if subjects did not consider anyone else’s noise-situation.
Reactions to aircraft noise resulting from an airport development vary considerably among individuals. This paper examines whether the noise level tolerated by individuals is affected when they compare their own situation to the situations of other people who are more severely affected by the noise. We modeled the individual noise tolerability by adopting the reference point concept and the value function of prospect theory. A questionnaire assessed different levels of noise-affected zones at a hypothetical airport. Individual noise tolerable level was measured by a prerecorded aircraft noise presented via headphones. Decision-making associated with the reported satisfaction level regarding the changes in operational flight frequency settings at the airport. An interview survey was conducted with residents near Manila airport in the Philippines. We applied genetic algorithm to jointly estimate the parameters for noise tolerability model and the value function. Results showed that individuals tolerated more overhead flights when they considered the situations of other people worse affected by the noise than they were. The tendency of noise tolerability increased with the severity of noise exposure situations of other people, but lower reactions to noise escalation. We also observed diminishing sensitivity to changes in noise relative to the noise tolerable level. The aircraft noise tolerability and the consideration of noise exposure situations of other people appeared to be a vital aspect to be considered in airport noise management and policy.
The maximum number of flights tolerated by airport-area residents is affected by their access to information concerning their neighbors who are affected by the noise. This study explored the effects of providing descriptions of noise exposure conditions on the tolerance of aircraft noise by residents living near Manila Airport in the Philippines. A questionnaire assessed different levels of noise in a hypothetical situation involving the affected zones. Face-to-face interviews were conducted using prerecorded aircraft noise presented via headphones. The information about the overall noise situation at an airport lowered the tolerance of overhead flights, compared to the baseline levels. The participants tolerated more flights when they were informed about the situation of people who were more severely affected by the noise than they were. This tendency strengthened with an increase in the severity of the noise situation in other areas. The economic benefits associated with an increase in air transport demand were also observed to boost noise tolerance. The findings provide insights into proper information provision, which should benefit the noise-management personnel of airports.
