One technology being employed to signiﬁ cantly reduce noise made by freight trains is
composite brake blocks. ‘K-blocks’, also known as ‘whispering brakes’, are now being
ﬁ tted to all new freight wagons in accordance with the ‘Noise TSI’ (Technical Speciﬁ cations
for Interoperability). K-blocks reduce noise at source by 8-10 decibels (dB) which, to
human ears, sounds like cutting the noise by half.
Rolling stock has a high life expectancy of up to 40 years, so the retroﬁ tting of the existing
ﬂ eet is crucial in order to meet EU noise targets. The...
The aim of this new interdisciplinary series is to promote the exchange of information
between scientists working in different fields, who are involved in the study of complex
systems, and to foster education and training of young scientists entering this rapidly
developing research area.
Most rubberwood sawmills in present day Thailand are of the band saw type.
Only the oldest ones still utilize circular saws despite the small diameter or the
raw material. A typical sawmill consists of two production lines of one break-
up saw and some four additional saws for resawing. The disadvantage of the
bandsaw is the high level of maintenance required. The saw blades need
sharpening every six hours by specially trained personnel using special
equipment (Status of… 2000).
The diagnosis? Eye-ear dissociation. The cause? Inappropriate training
of the auditory brain cortex (see the previous Listening chapter). People
can be perfect readers, but, at the same time, poor listeners. (The
contrary – the ears understand, but the eyes cannot read – exists too:
illiteracy.) To neuroscientists, this is not surprising; eyes and ears are
different entry ports for distinct elaboration and storage sites in the
brain. Training the visual brain areas at the back of the head (see Figure
3.3) has little influence on the performance of the auditory brain areas.
