NOISE
Sound is mostly pleasant but it can be very disturbing if too
loud. Such sound is called noise. It can come from nature
(thunder, the sound of a waterfall) but often it is produced
by man (traffic, machinery and other such devices). Long and
frequent exposure to noise should be avoided because it can
damage hearing.
When do you think Bistra was the noisiest? When it was
inhabited by monks, when the nobility lived here or perhaps
today, with so many visitors?
SOUND and NOISE
It is difficult to draw a line between sound and noise because
it depends both on the listener and the circumstances.
Sounds experienced by someone as noise could be totally
pleasant to another (such as listening to loud music, the
sound of a racing car or computer games). It is also known
that the person who produces a sound finds it less disturbing
that the person who only listens to it.
From the sounds in the book, pick the one that you find most
pleasant and the one you think is just noise.
NO SILENCE
The opposite of sound is silence – which cannot be
experienced by a normal-hearing person in everyday life.
A special insulated room called an anechoic chamber is as
close as it gets. Although we all sometimes want to be 'left
in silence', we actually feel rather uncomfortable in a room
completely free of all sound.
Visit the Technical Museum of Slovenia where you will find a
genuine anechoic chamber in the Almost Everything About Sound
exhibition. See for yourself what it feels like in a room insulated
from any exterior sound.
SILENCE
There are people who live in absolute silence because of a hearing
impairment. They communicate with a special sign language based
on hand movements, the expressions of the face, mouth and lips
and by body movement.
However, despite having excellent hearing, we still don't hear
certain things. You may be very familiar with the complaint:
» I can't hear!« Well, the reason might be that we don't hear
because we simply don't want to...
