The dinner in the Christchurch Town Hall commenced with a spirited explanation
of the design and acoustics by Sir Miles Warren and Dr. Harold Marshall. The
excellent acoustics was aptly demonstrated by the music from the string quartet
and the clarity with which announcements from the stage were understood. The
conference was certainly a great success and there is already talk of the next
combined conference.
JAPAN
Railway is a major transportation system in Japan and its competitors are
road and air transportations. The traffic noises from these competitors are
already regulated and well monitored. However, the railway noise, except the
Shinkansen or high speed train at a speed of above 200km/h, has been excluded
from the Japanese noise regulations. Due to the recent increase in the numbers
of complaints to commuter train noise, the Ministry of the Environment decided
to collect noise level data around railways. The first step is to set up the noise
measuring method. In 2006, the ministry contracted with INCE/Japan and the
working group was organized. The measured level will be L A
,S max
that is the
same one as the Shinkansen railway noise and L AE
for L Aeq
that many countries
introduce as noise immission level.
