1. Masayuki Takada, Shinji Sakamoto, Shin-ichiro Iwamiya, Investigation of the design direction of vehicle door-closing sounds, Proceedings of 46th International Congress and Exposition on Noise Control Engineering (INTER NOISE 2017), paper number.510, 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..
2. 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..

Kazuhiko Kawahara, Masayuki Takada, Shin-ichiro Iwamiya, Toshihiro Ito, Transferring technical listening training curriculum at the Department of Acoustic Design, Kyushu University, to a corporation in the acoustics industry, Acoustical Science and Technology, 37, 4, 157-164, 2016.07, Technical listening training (TLT) is a systematic training program designed to improve
auditory sensitivity. TLT consists of discrimination and identification tasks for a wide variety of acoustic features, e.g., frequency, sound pressure level, and spectrum pattern. To improve the auditory sensitivity of employees in a corporation in the acoustics industry, the TLT curriculum at the Department of Acoustic Design, Kyushu University (KU), was transferred to the corporation as part of a corporate education program. An initial 5-day trial course was carried out by the KU staff to demonstrate the process of KU-style TLT and its effectiveness to the corporate staff. After the creation of a TLT control system and training room, a second trial 11-day course was jointly carried out by KU and the corporate staff as a simulation of the TLT course in the corporation. Participants in the trials were engineers in the corporation. Through the TLT trials, they improved their auditory sensitivity and
their understanding of the relationship between acoustic properties and auditory attributes. They recognized the importance of the systematic listening experiences provided by TLT. Through these two trials, the corporate staff gained understanding of the TLT curriculum. Therefore, the corporation has begun running the TLT curriculum smoothly and successfully..

11. Katsuya Yamauchi, Daniel Menzel, Masayuki Takada, Koji Nagahata, Shin-ichiro Iwamiya, Hugo Fastl, Psychoacoustic examination of feasible level of additional warning sound for quiet vehicles, Acoustical Science and Technology, 36, 2, 120-125, 2015.02, The reduced noise of electric and hybrid electric vehicles has been of particular concern because of the potential danger that these vehicles pose to pedestrians when their approach is inaudible against background noise. To address this issue, the use of additional warning sounds in such vehicles is being considered in various countries. The aim of this study was to examine the feasible level of the warning sounds in some urban environments. The levels of three candidate warning sounds (sound of car horn, engine sound, and band-pass noise) were adjusted by the study subjects against four types of urban background noise presented in a laboratory environment. The subjects were asked to adjust the level of the warning sounds so that they were reliably audible or just detectable. The results showed that the level of background noise and type of warning sound significantly affected the perception of the warning sounds, but there was no significant cross-cultural difference between the German and Japanese subject groups. The observations showed that a warning sound that was reliably audible in a particular environment might be inaudible in another environment approximately 10 to 20 dB noisier. The results were also compared with current recommended levels of warning sounds for quiet vehicles..
12. Satoshi Suzuki, Masayuki Takada, Ki-Hong KIM, Shin-ichiro Iwamiya, Survey on vehicle horn use in South Korea, Proceedings of Kyushu-Youngnam Joint Conference on Acoustics 2015, 103-106, 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..
13. 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..
14. Masayuki Takada, Satoshi Suzuki, Ki-Hong KIM, Shin-ichiro Iwamiya, Survey on vehicle horn use in urban areas of Korea, Proceedings of 43rd International Congress on Noise Control Engineering (INTER NOISE 2014), paper number.569, 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, Proceedings of 42nd International Congress and Exposition on Noise Control Engineering (INTER NOISE 2013), paper ID.656, 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..
