“…Several cities in other countries have faced noise problems relating to the use of car and motorbike horns [18][19][20]. In such areas, it may be necessary to conduct a similar survey on vehicle horn use as a first step to implementing countermeasures.…”

The Japanese Road Traffic Law states that a vehicle horn should be used only in an emergency or in dangerous locations where a horn sign has been installed. However, drivers frequently use their vehicle horn as a signal when passing each other. Furthermore, pedestrians and cyclists are also honked at by drivers. There may be a negative effect of vehicle horn use on people outside the vehicle. Therefore, a questionnaire survey was carried out to ascertain the current circumstances of vehicle horn use. Respondents were asked about the latest or last-remembered instance of horn use in various situations, both when they were driving and when they were pedestrians. With regard to experiences of being honked at by another driver, the questionnaire included questions concerning place, traffic volume, the aim of horn use, the timing pattern of horn use, and the respondent's psychological reaction when honked at by another driver. It was found that drivers briefly honked their horn to express gratitude, or to gain another's attention, in various places. Long honks such as one long honk or two long honks mostly evoked negative psychological reactions in drivers, such as a feeling that the sound of the horn was startling, noisy, or irritating. Furthermore, pedestrians frequently had negative psychological reactions to horns used to gain their attention or to alert them to danger. More than 40% of nondrivers were displeased with the volume and sound quality of horns.

“…18 There is a significant effect of background noise level (p < 0.01) on annoyance. 19 The relationship between loudness and annoyance of noises are widely studied; basically, annoyance as well as negative effects on performance will increase with increasing sound level, tonal character of the noise, and variability of the exposure. 12 Annoyance also depends upon the type of noise.…”

Acoustic properties of residential building are often neglected by designers, developers, contractors, and even home buyers. Noises from both the internal and external environments affect occupants' daily lives. This motivates the current study which aims to identify all types of audible noises in Malaysian residential buildings and to determine the physical and psychological impacts of noise loudness and annoyance on occupants in various types of residential buildings. A questionnaire was conducted covering 19 types of noises in residential buildings with participants assessing the loudness and annoyance level. There were 171 valid forms collected from around Malaysia for analysis from 1000 posted forms, responding rate of 17.1%. Traffic noises were deemed as the most undesired type of noise, followed by the noises from neighbors and animals. More interestingly, the annoyance experienced in relation to noise from traffic and neighbors was inter-correlated. While many animal noises such as birds chirping, rooster calls, and insect noise cause little irritation to occupants, dogs barking are significantly more annoying to the occupants. Job stress and occupants' sensitivity to noise are highly correlated with many types of noises. Generally, the influences of human-related factors are more significantly related to the housing-related factors on the perceived noise loudness and annoyance. Practical application: The result of this study could directly assist building developers and architects to enhance the acoustic (sound) properties of residential buildings. This study will guide potential property buyers how to look into the acoustic performance of the building that they are going to purchase and to stay in. All types of audible noises annoying residents in full range of residential buildings are identified and categorized in this study. The loudness and annoyance of each type of noise to resident occupants were addressed. The physical and psychological impacts of noise loudness and annoyance to the occupants in different type of residential buildings are determined, which will improve the fullness of industry standards as well regarding acoustic concern as a trend.

“…The maps illustrate that the noise levels remain over 50 dBA and can exceed 70 dBA at the nearside of major roads and highways. This is considered relatively high since the accepted level is 65 dBA [13], [14]. One expects that those residents near highways and main roads suffer from excessive noise if windows of their houses are opened.…”

“…Noise is also a major environmental problem in Nigeria, with traffic noise bothering the people most [5], [6]. In Vietnam, Phan et al [7], [8] conducted a large-scale socio-acoustic survey of community response to road traffic noise in Hanoi and Ho Chi Minh cities to investigate human reactions to road traffic noise in these two Vietnamese large cities. The noise exposure level (L den ) equals 75-83 dB.…”

Abstract-Riyadh City, the capital of the Kingdom of Saudi Arabia, has been subjected to continual increase in road traffic due to overall increase in prosperity, fast development and expansion of economy. In this paper, the first round of noise mapping for Riyadh City is developed by using the Predictor-LimA 7810 software. Road traffic data were measured or estimated as accurate as possible in order to obtain reliable noise maps. The simulation results at some chosen locations are validated by actual field measurements, which are obtained by a system that consists of a sound level meter, a GPS receiver and a database to manage the measured data. The maps show that noise levels remain over 50 dBA and can exceed 70 dBA at the nearside of major roads and highways.
