For the purpose of finding how the annoyance response to aircraft noise is affected by non-noise variables, the questionnaire survey is conducted around the Gimpo International Airport in Seoul, Korea. The non-noise variables used in this research are divided into two categories; demographic and attitudinal variables. The result of the survey suggests that aircraft noise annoyance is not affected to an important extent by other noise sources(e.g., road traffic noise and community noise etc.) and the demographic variables (sex, age, education, occupation, dwelling type and length of residence). It has been found that it is affected to an important extent by the attitudinal variables such as complaints.

The aim of this study was to determine principal non-acoustical factors for noise annoyance in the vicinity of Kimpo Airport in Seoul, Korea. Noise annoyance was estimated using self-reported annoyance scale. We have conducted a social survey aiming to identify the main sound sources, evaluate the annoyance and analyse the main effects of noise on people. Acoustical and non-acoustical variables are expected to greatly affect annoyance responses. This study divided acoustical variables into aircraft, road traffic and neighboring noises, and non-acoustical variables into demographic, situational and attitudinal variables. The study performed multiple regression analysis to determine the influences each variable has on annoyance responses. Acoustical variables affect noise annoyance to aircraft and neighboring noise except road traffic noise. For road traffic and neighboring noise annoyance was affected by non-acoustical variable, insulation by housing type. For aircraft noise, main noise source of this area, annoyance was affected by acoustical variable and some non-acoustical variables, mainly exposure time.

자료분석 결과 발견된 사실들을 정리해 보면 다음과 같다. 첫째, 직장에서 발생하는 성적 성가심에 대해 상대적으로 적극적으로 대응하는 여성들은 약 50.6%정도로 나타났다. 이 중에서도 성적 성가심에 대해서 불쾌하게 인식하는 정도도 상대적으로 높고, 불쾌감을 상대에게 표현하며 대응하는 정도도 상대적으로 높은 여성들은 전체 응답자(736명)중에서 약 40%(294명)정도 였다. 성적 성가심에 대하여 불쾌함을 인식하는 정도는 상대적으로 낮으나 상대에게 불쾌함을 표현하며 대응하는 수준은 상대적으로 높은 여성들이 약 10.7%(79명)로 나타났다. 반면에 성적 성가심에 대하여 불쾌하게 인식하는 정도도 상대적으로 낮고 불쾌함을 상대에게 표현하는 정도도 낮은 여성들이 약 32.8%(242명)나 되었다. 약 16.4%(121명)의 여성들은 성적 성가심 상황에서 불쾌하게 인식하는 정도가 상대적으로 높으면서도 상대에게 불쾌감을 표현하며 대응하는 정도는 상대적으로 낮았다. <표 4> 둘째, 직장에서 발생하는 성적 성가심 상황에서 여성이 상대에게 성적 성가심에 대한 자신의 불쾌함을 표현하며 대응하는 능력은 여성의 심리적 특성인 대인의존성과 밀접한 관계가 있다는 사실을 명백하게 확인하였다. 성적 성가심 상황에서 성적 성가심에 대해 상대적으로 불쾌하다고 인식하는 정도가 높으면서 불쾌감을 표현하고 대응하는 수준은 상대적으로 낮은 여성들은 대인 의존도가 상대적으로 높았고, 반대로 성적성가심에 대해 상대적으로 불쾌하게 인식하는 정도가 상대적으로 낮으면서 불쾌감을 표현하며 대응하는 수준은 상대적으로 높은 여성들은 대인 의존도가 상대적으로 높게 나타났는데 이는 주목할만한 사실이다. 세째, 성장시 부모의 상호작용 유형이 성적 성가심과 같은 이성과의 상황에서의 여성들의 대응 반응과 밀접한 관련성이 있음을 발견하였다. 성장시 아버지가 지배적이고 어머니가 순종적인 특성이 뚜렷한 가정에서 성장한 여성들은 부모의 상호작용 유형이 동등한 가정 분위기에서 양육된 여성들에 비해 성적 성가심 상황에서 불쾌함을 표현하며 상대에게 대응하는 수준(강도)자체가 훨씬 낮았고, 성적 성가심에 대해 자신이 불쾌하게 생각하는 정도보다 상대적으로 훨씬 약한 소극적인 대응반응을 보이는 사실도 확인되었다. 성적 성가심 상황에서 상대 남성에 대한 여성들의 대응 반응은 성장시 남성인 아버지에 대한 여성인 어머니의 태도 및 행동의 재현(reenactment)현상으로 나타났다고 해석할 수 있다. 이러한 발견은 특히 동성인 부모가 성역활 사회화의 가장 강력한 모델이라는 학습 이론가들의 주장을 거듭 뒷받침하여 준다.

For the purpose of finding how aircraft noise annoyance response is affected by variables when noise survey is performed, the questionnaire survey is conducted around the Gimpo International Airport in Seoul, Republic of Korea. This residential area is exposed to the aircraft noise and road traffic noise, simultaneously. Research areas are classified according to three different aircraft noise exposure levels expressed in WECPNL, under 75, between 75 and 80, and above 80 WECPNL, on aircraft noise map. The 7-step numerical magnitude with verbal category scales is used to measure the annoyance level. This survey suggests that aircraft noise annoyance is not affected to an important extent by other noise sources(road traffic noise, community noise) and demographic variables(sex, age, education, occupation, dwelling type, length of residence).

In recent years, public complaints about railroad noise by KTX and Ordinary train are increasing. Restriction of railways uses same standard without distinguishing the type of railways. According to the type of railways, the frequency characteristics of emitting noise is different. Therefore it is requested to know how vary the public response to each types of railway. The noise annoyance to three types of trains (KTX, Electric train, Diesel train) was analyzed by Jury Evaluation Test for assessing the effect of frequency characteristics. The numerical results by a Semantic Differential Method showed that annoyance response to three type of trains depended on the frequency characteristics. As a result, this study proposed that the KTX could have a bonus level of maximum 2.9dB(A) to ordinary train.

This research presents a laboratory study about an annoyance of impulsive sound caused by construction site(breaker and blasting). The sources are sampled from outdoor noise and their levels range from 40 to 75 dB at the interval of 5dB. The noise unit is based on A-weighted sound exposure level (ASEL; $L_{AE}$). To make equal ASEL of outdoor noise, finite impulse response (FIR) filter is applied to the originally sampled source to include the effect of distance attenuation. The evaluation method of jury test adopted a Semantic Difference Method (SDM). In the result of the Jury test for impulsive noise, the annoyance response of blasting noise was higher than that of breaker noise.

Measurement of noise is not only to know the information of acoustic pressure but to assess human response for noise. Provided that want to find human response for transportation noise, we will have to reproduce the measured noise. The method of reproduction is largely divided into monaural and binaural reproduction techniques. Human fundamentally hears sound through both ears, which is binaural hearing. And binaural technique includes the more information of physical phenomena like acoustical reflection and deflection. So, binaural reproduction is more suitable for assessment of the psychoacoustical and physiological response for transportation noise exposures.

The multiple regression analysis and path analysis in each dominant area of noise source are conducted to analyze the relationship between dependent variables like annoyance and independent ones such as noise and non-noise factors. The multiple regression analysis shows that impact of noise factors is the highest to annoyance in dominant areas of road traffic and railway noise. Meanwhile, impact of non-noise factors such as sensitivity and satisfaction of environment on annoyance is also high in these areas. The path analysis result for multivariate analysis between various independent and dependent variables is similar to that of the multiple regression analysis. However, noise factor is the greatest factor influent on annoyance in the dominant areas of the combined noise, and relationship between annoyance and sensitivity is the highest in combined area exposed to road traffic noise and railway noise.

The noise problem has been a public interest for several years in Korea. Especially, the noises which were emitted from aircrafts on the airport and in the air have injurious effects on people over a vast range. Hence, there need vast data on the aircraft noise to evaluate the effect of various parameters. In present study, the works which consist of social surveys and noise measurements were conducted at points near the airport and the airbase. Total of 1,784 participants give effective responses in forty-five areas nearby the measurement points. Questionnaires asked the responses concerned with attitude, noise sensitivity, directive effects, secondary effects, annoyance and attempts to lower noise level exposed. From the field survey, the doseresponse relationship of community response to aircraft noise was established and there are different characteristics between civil and military aircraft. Though the study is still continuing on a few interest, one among some results is that %HA (%highly annoyed) of civil aircraft is higher than military's under the 70 WECPNL.
