Masayuki Takada, Shoki Tsunekawa, Kazuma Hashimoto, Tamaki Inada, Yoshinao Oeda, Katsuya Yamauchi, Ki-Hong Kim, Shin-ichiro Iwamiya, Analysis of vehicle horn use and factors at intersections in an urban area of Taiwan, ICA2019, 2019.09, In urban areas in many countries, noise pollution is generated by the frequent use of car and motorcycle horns. The final goal of the present study is to clarify the causes of horn use and to propose a transportation system to suppress horn use. To this end, we have investigated relationships between horn use and factors such as driver awareness, behavior, and vehicular environment. Our previous study investigated causal relationships between horn use and the vehicular environment in Taiwan, and found that horn use was more frequent when gridlock occurred at intersections. The present study analyzed details of gridlock situations at three intersections in Taipei during which vehicle horns were used. We found many cases where honking began after vehicles entered the intersection to turn left during the green-light phase. In particular, drivers often used their horns when they had to wait for more than 4 seconds for the vehicles in front of them to start moving after a green light allowed left turns. Logistic regression analysis revealed that the probability of a driver using a vehicle horn was significantly affected by the duration between the signal turning green and the vehicle in front of them starting to move..

44. Shoki Tsunekawa, Kazuma Hashimoto, Tamaki Inada, Masayuki Takada, Yoshinao Oeda, Katsuya Yamauchi, Ki-Hong Kim, Shin-ichiro Iwamiya, Survey on vehicle horn use at intersections in Taipei City, Taiwan, INTER NOISE 2018, 2018.08, Car horns were originally installed in vehicles for safety. However, many urban areas in several countries face serious noise problems related to the use of car and motorbike horns. The ultimate goals of the present study are to clarify the causes of driver horn use and to propose a transportation system that suppresses horn use. To this end, relationships between horn use and factors including driver awareness and behaviour, the vehicular environment and the transportation system should be investigated. The present study therefore conducted surveys to grasp the current circumstances of horn use and traffic at three intersections in an urban area of Taiwan. It was found that the frequency of honking increased with the traffic volume during hours other than weekday rush hours. It is supposed that high traffic volumes during the morning and evening rush hours on weekdays were due to the presence of many motorcycles. In terms of vehicle type, the relationship between driver horn use and the traffic volume of standard-sized vehicles was found. Moreover, the analysis of horn use during traffic signal cycles at each intersection revealed that the frequency of horn use increased when left-turning vehicles obstructed traffic in other lanes. .
45. Masayuki Takada, Kohei Iida, Shoki Tsunekawa, Shin-ichiro Iwamiya, Sound quality evaluation of noise emitted from brush cutters, INTER NOISE 2018, 2018.08, Engine-driven brush cutters generally generate noise with a high sound pressure level. Although such noise should be attenuated as a first countermeasure, improved design of the sound quality is another valid approach. The perceived quality of noise emitted by brush cutters operated at various engine speeds was measured using a semantic differential method. Stimuli induced, for example, muddy, rough, noisy and unpleasant impressions. There was a difference in the impression of undulation between two-stroke-engine sounds and four-stroke-engine sounds. Furthermore, correlation analysis between rating results and metrics indicated that the perceived quality was affected by loudness. We therefore then employed stimuli having the same loudness. Results of semantic differential experiments revealed that two-stroke-engine sounds were rated as being significantly more undulating and unpleasant than four-stroke-engine sounds at various engine speeds. Furthermore, the impression of unpleasantness was significantly correlated with that of undulation for a wide range of engine speeds. It was supposed that the impression of undulation is related to the fluctuating temporal envelope created by unstable salient peaks in the waveform of stimuli, which are likely caused by the incomplete internal combustion of fuel..
46. Masayuki Takada, Shinji Sakamoto, Shin-ichiro Iwamiya, Investigation of the design direction of vehicle door-closing sounds, INTER NOISE 2017, 2017.08, Vehicle door-closing sounds affect the commercial value of vehicles. In our previous study, factors affecting the value evaluation of door-closing sounds and the structure of the evaluation were investigated. Although we obtained major factors and structures, details such as differences in factors among door-closing sounds and differences due to participants’ preferences were not considered. To clarify such details, psychoacoustical experiments using the evaluation grid method were conducted in the present study. Pairs of door-closing sounds were presented to participants. Participants were asked to select the more satisfactory stimulus and to give reasons for their selection so as to clarify original evaluation factors (i.e., perspectives in evaluation). Furthermore, to elicit factors relevant to the obtained evaluation factors, participants were asked the reason why they provided the original evaluation factors and their detailed concrete requirements of door-closing sounds. Text mining was applied to participants’ answers. In the beginning of analysis, we attached tags such as stimuli (what kinds of stimuli were described), negative/positive (whether answers were given in the positive context or not) and enthusiastic/unenthusiastic feelings about cars (whether answers were given by car enthusiasts or not) to all answers. Correspondence analysis was applied to the sentence-word (tag) table obtained by the text-mining procedure. As a result, a two-dimensional solution displaying relationships in terms of location among words and tags was obtained. Furthermore, through hierarchical cluster analysis, words and tags were classified into five clusters. One of the clusters comprised the tag “positive” and words such as “heavy”, “solidly made”, “low pitch” and “bass”. Such relationships were similar to major structures of the value evaluation obtained in our previous study. Results also revealed relationships concerning other tags. Words related to tags such as “positive” and “enthusiastic” are supposed to indicate the design direction of door-closing sounds..

Masashi Miyazaki, Rikako Tajima, Masayuki Takada, Shin-ichiro Iwamiya, Factors of Driver's Horn Use and Its Effect on Other Drivers and Pedestrians, Youngnam-Kyushu Joint Conference on Acoustics 2017, 2017.02, Questionnaire surveys were carried out to investigate the current state of a vehicle horn use and its effects on drivers and pedestrians in Fukuoka, Japan. In the questionnaire, respondents were asked about the latest or last-remembered case of vehicle horn use. The questionnaire sought details such as the aim of horn use, timing pattern of honking, and respondent's psychological reaction when honked at. Furthermore, we studied on the intrinsic factors affecting driver's own horn use as the traffic behavior (i.e., driver awareness about horn use). The results showed that
drivers frequently honked not only to alert another to danger or gain another's attention but also to express gratitude. Moreover, pedestrians had negative psychological reactions more frequently than drivers. According to analysis of the intrinsic factors affecting driver's own horn use, it seemed that the drivers’ behavioral intentions of honking were frequently induced in drivers with positive attitudes toward horn use, and who usually honked their horn for questions concerning driver awareness about horn use. Drivers whose behavioral intentions were more frequently induced often used their horn for purposes of expressing gratitude and venting anger..

73. Satoshi Suzuki, Masayuki Takada, Ki-Hong Kim, Shin-ichiro Iwamiya, Survey on vehicle horn use in South Korea, Kyushu-Youngnam Joint Conference on Acoustics 2015, 2015.01, We have previously carried out questionnaire surveys to investigate the current state of vehicle horn use in Japan. Several cities in other countries also face noise problems relating to the use of horns. Our survey design will provide information on the reasons for vehicle horn use in such areas, which can subsequently be used to design countermeasures to reduce any adverse effects. Therefore, similar surveys were conducted to investigate the current state and driver awareness of vehicle horn use in South Korea. The totaled results show that when honked at, pedestrians had a more negative psychological reaction than drivers. Results concerning driver awareness revealed that fewer drivers paid attention to the annoyance caused by vehicle horn use of people outside the vehicle, such as pedestrians and cyclists, than drivers who noticed a similar reaction from other drivers. The results of cross tabulation revealed that many pedestrians were startled by short honks for the purpose of alerting them to danger. The cross tabulation also showed that drivers who did not usually use horns did use a brief honk for the purpose of alerting another to danger and gaining another’s attention through necessity..

75. Masayuki Takada, Satoshi Suzuki, Ki-Hong Kim, Shin-ichiro Iwamiya, Survey on vehicle horn use in urban areas of Korea, INTER NOISE 2014, 2014.11, In previous studies, we carried out questionnaire surveys to investigate the current circumstances of vehicle horn use and the effects of horn use on drivers and pedestrians in Japan. Several cities in other countries face noise problems relating to the use of car and motorbike horns. Our survey design might help obtain information on the circumstances of vehicle horn use in such areas, which can subsequently be used to design countermeasures to reduce adverse effects. Therefore, we conducted a similar survey on horn use in South Korea. Measurement of noise at a crossroad with heavy traffic revealed more than 100 uses of the horn per hour. The questionnaire 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 with a single honk, two short honks and a long honk. Such honking mostly aroused negative psychological reactions such as the respondent finding the horn use startling, noisy, or irritating. There were no significant relationships between questionnaire items of the driver’s own horn use, suggesting there is no particular manner of the driver’s own horn use..

Masayuki Takada, Satoshi Suzuki, Shin-ichiro Iwamiya, Kuniya Matsuura, Masahiro Yamaguchi, Shouichi Yoshikawa, Evaluation of the perceived impulsiveness of operating noise emitted by office equipment with attachments installed, INTER NOISE 2013, 2013.09, Impact sounds are occasionally generated by the attachments (e.g., a punching system and document feeders) of office equipment (e.g., multifunction peripherals) in addition to the body of the office equipment generating noise and thus affect the equipment’s sound quality. To investigate the effects of acoustic characteristics of the impact sounds of attachments on the perceived impulsiveness of the noise emitted by multifunction peripherals, psychoacoustical experiments were carried out using synthesized operating noise including impact sounds of attachments in which the spectral features, the degree of salience of the impact sounds and the cycle duration between sounds were systematically varied. The results revealed that impressions of impulsiveness increased as the energy of high-frequency components increased and the cycle duration became shorter. The perceived impulsiveness was highly correlated with an acoustic measure of the fifth percentile of the sound pressure level (LA5), which was also correlated with a similar impression in a previous study. Logistic regression analysis, in which the relationship between the proportions of participants who evaluated the stimuli as bothersome and LA5 was investigated, revealed that LA5 values of stimuli that were evaluated as being bothersome by more than half the participants were around 50 dB..

Furthermore, pedestrians are also tooted at by drivers. Such horn use may result in a 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. 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 tooted 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 mental reaction. The results for the Kansai area revealed that a single toot and two short toots were frequently used to gain pedestrians’ attention, and they aroused negative mental reactions such as the respondent feeling startled or considering the tooting noisy. On the other hand, Kanto results showed that not only short toots but also a long toot were frequently used to gain pedestrians’ attention or to alert pedestrians to danger, and they aroused negative mental reactions more frequently than was the case in Kansai. The manner of driver’s own horn use is similar among the three areas including Fukuoka in which the previous survey was conducted. .
