1. Masayuki Takada, Satoshi Suzuki, Ki-Hong Kim, Jong-Hyun Shin, Shin-ichiro Iwamiya, Driver's vehicle horn use and its effects on other drivers and pedestrians: A case study in South Korea, Mechanical Engineering Journal, 4, 2, Paper No.16-00433, 16 pages, 2017.04, In previous studies, questionnaire surveys were used to investigate the current ircumstances of vehicle horn use and its effects on drivers and pedestrians in Japan. Several cities in other countries face more serious noise problems related to the use of car and motorbike horns. In urban areas of South Korea, frequent vehicle horn use on roads was found through onsite inspections. Measurements of noise at crossroads with heavy traffic revealed frequent horn use with high sound pressure level. In such areas, it is necessary to clarify the current circumstances of vehicle horn use, including its effects. Therefore, a survey on such use, similar to the previous work, was carried out. The survey included questions on the latest or last-remembered case of horn use in various situations in which the respondent was a driver or pedestrian. It was found that many pedestrians had experiences of being honked at by a single honk, two short honks and a long honk. Such honking mostly aroused negative psychological reactions such as feeling startled, a sensation of noisiness and feeling irritated.
There were no significant relationships between questionnaire items regarding the driver’s own horn use, suggesting there is no particular manner of such use. Relationships between driver awareness of their own horn use and its mode suggested that drivers who did not usually honk had feelings of reluctance to use the horn, and that they briefly honked out of necessity..

Masayuki Takada, Honatsu Murasato, Shin-ichiro Iwamiya, Comparisons of vehicle horn use in urban areas of Japan, Acoustical Science and Technology, 35, 6, 309-317, 2014.11, In Japan, drivers frequently use their vehicle horn as a signal in various situations such as when passing each other. Furthermore, pedestrians are honked at by drivers. Such horn use may create noise problem for people nearby. Therefore, a questionnaire survey was carried out to ascertain the current circumstance of vehicle horn use in Kanto and Kansai of Japan, while a similar survey was previously carried out in Fukuoka. Respondents were asked about the latest or last-remembered case of horn use in various situations of being drivers and pedestrians. With regard to an experience of being honked at by another driver, the questionnaire included questions relating to the aim of horn use, the timing pattern of the horn, and the respondent’s psychological reaction. The results revealed that drivers’ brief and frequent vehicle horn use to express gratitude or gain another’s attention in various places from narrow lanes to main roads was similar among the three surveyed areas including Fukuoka. Long honks and horn use to gain another’s attention or to alert another to danger remarkably aroused negative psychological reactions in pedestrians. No significant difference in the manner of the driver’s horn use was found among the three surveyed areas..

Masayuki Takada, Hiroaki Mori, Shinji Sakamoto, Shin-ichiro Iwamiya, Structural analysis of the value evaluation of vehicle door-closing sounds, The 22nd International Congress on Acoustics (ICA2016), 2016.09, Vehicle door-closing sounds affect the commercial value of vehicles. To create a door-closing sound that adds vehicle value, it is necessary to grasp and control factors affecting the value evaluation, such as the sound quality and imagery associated with the door-closing sound. The present study conducts psychoacoustic experiments to comprehensively investigate factors affecting the value evaluation of door-closing sounds and its structure using the evaluation grid method. Pairs of door-closing sounds were presented to participants. They were asked to select the more satisfactory stimulus and to give reasons for their selection so as to clarify the “original evaluation factors” (i.e., perspectives in evaluation). Furthermore, to elicit factors relevant to the obtained evaluation factors at the higher/lower levels of the hierarchical structure, participants were asked to identify benefits (i.e., reasons why they provided the original evaluation factors) and their detailed concrete requirements (mainly acoustic characteristics of stimuli). The overall structure was obtained from relationships between original evaluation factors and elicited factors at the higher/lower levels for all paired comparisons of door-closing sounds of all participants. The results reveal that door-closing sounds with abundant low-frequency contents and rapidly damped energy aroused feelings of massiveness and door closing. Furthermore, these feelings were related to emotional benefits such as a sense of security and an impression of the luxuriousness of the vehicle. Relationships between ratings of paired comparisons and metrics confirmed the effects of acoustic features of door-closing sounds found in the structure. The results suggest factors important to the design of door-closing sounds..
