4. The 2017 Annual Conference of the Acoustical Society of China will be held in Harbin, China in September 2017( It will be organized in a new form to improve the high-level communication on research of acoustics and to broaden the platform to promote a rapid growth of more new-rising researchers. Therefore, much more plenary speakers will be present in this conference and a special forum and excellent paper awards for young scholars will be set up. Sixteen sessions will be held consisting of invited lectures from important fields of acoustical researches (e.g., environmental acoustics, noise and vibration control, structural and architectural acoustics, and mechanical vibration and shock).

5. Researchers at the Institute of Acoustics (IOA) of the Chinese Academy of Sciences have designed and fabricated an underwater acoustic carpet cloak using transformation acoustics—a scientific first. It is reported by several media such as Chinese Academy of Sciences (, Eurekalert! (, Asian Scientist Magazine (, (, and Science Newsline ( The photograph for its fabricated sample is shown in Figure 1.

Announcement of ‘Noise Guidelines for Wind Power Generation Facilities’

The Japan Ministry of the Environment announced new noise guidelines for wind power generation facilities as advice based on the Local Autonomy Act to all prefecture governors, mayors, and heads of special wards on Friday May 26, 2017 ( in Japanese). Simultaneously, the ministry published a guidance manual for the measurement of wind turbine noise ( in Japanese). The guidelines and manual were established based on the results of an investigation that the ministry carried out to examine the way to evaluate wind turbine noise appropriately for four years from fiscal 2013. The noise evaluation index is based on A-weighted sound pressure level. As wind power generation facilities are often constructed in extremely quiet regions, such as mountainous areas, the level of environmental noise changes dependent on the occurrence of transient sounds such as a car passing by. Thus, as shown in Figure 1 (bottom), the guideline value was set to be a level of ‘5 dB higher than the level of residual background sound.’ However, the level of residual background sound can be too low compared to the level of usual living sound environment, and a lower bound was introduced on the guideline value as shown in Figure 1 (top). The lower bound is set to 35 dB when the level of residual background sound is lower than 30 dB and when quiet must be preserved, such as schools, hospitals, and places where soundscape should be kept. Otherwise, it is set to 40 dB.

In addition, INCE/J held a workshop on the control of noise, vibration, and odor nuisance for administrative officers in local governments under the cosponsorship with Japan Association on Odor Environment on Monday October 31, 2016, in Tokyo.

INCE/J carried out two contract research works commissioned by the Ministry of the Environment. In one contract, INCE/J compiled a draft guidance manual for the measurement of wind turbine noise, prepared a plan of noise measurement and social survey for high-speed railway noise, and created a brochure for the dissemination of basic knowledge and noise control policy of Noise Control Act. The other was an investigation on the method of measurement and evaluation of aircraft noise toward the revision of the guidance manual for airport noise.

Recent Trial on Sound Branding Strategy in Japan

Kyoto Tango Railway, a local train company near Kyoto, renewed signal sound melodies notifying train arrival and departure and background music in a special train “Tango Kuromatsu” and in the station building on Saturday April 1, 2017 ( in Japanese). Comfort and good impression in traveling and train waiting are intended to increase by sound design and branding strategy. The new sounds were designed featuring the images of regional characteristics of the three branch lines under the cooperation with Masafumi Komatsu, who is an environment music player as well as a research professor at Kyoto Seika University studying sound design in public space such as hospital, museum and planetarium.
