humans. British scientists have shown in a controlled experiment
that the extreme bass sound known as infrasound produces a range of
bizarre effects in people including anxiety, extreme sorrow and
chills supporting popular suggestions of a link between
infrasound and strange sensations.
NORMALLY YOU cant hear it, Richard Lord, an acoustic scientist
at the National Physical Laboratory in England who worked on the
project, said Monday.
Lord and his colleagues, who produced infrasound with a 23-foot
(7-meter) pipe and tested its impact on 750 people at a concert,
said infrasound is also generated by natural phenomena.
Some scientists have suggested that this level of sound may be
present at some allegedly haunted sites and so cause people to have
odd sensations that they attribute to a ghost our findings
support these ideas, said Professor Richard Wiseman, a
psychologist at the University of Hertfordshire in southern
England.
REACTIONS TO
INFRASOUND
Lord and Wiseman played four contemporary pieces of live music,
including some laced with infrasound, at a London concert hall and
asked the audience to describe their reactions to the music.
The audience did not know which pieces included infrasound, but 22
percent reported more unusual experiences when it was present in
the music.
Their unusual experiences included feeling uneasy or sorrowful,
getting chills down the spine or nervous feelings of revulsion or
fear.
These results suggest that low frequency sound can cause people to
have unusual experiences even though they cannot consciously detect
infrasound, said Wiseman, who presented his findings to the
British Association science conference.
NATURAL
PHENOMENON
Infrasound is also produced by storms, seasonal winds and weather
patterns and some types of earthquakes. Animals such as elephants
also use infrasound to communicate over long distances or as
weapons to repel foes.
So much has been said about infrasound its been associated with
just about everything from beam weapons to bad driving. Its
wonderful to be able to examine the evidence, said Sarah Angliss,
a composer and engineer who worked on the project.

i read in a book, it was a story about this well known horror
actor who faked his death to keep his castle, and keep others out.
what he did was play a really low bass note on a player *this is a
very old book btw* and hv stuff like dry ice, echo rooms stuff like
that. so his castle became a renouned haunted site.
he has stuff like secret passage ways behind castle walls, and he
imported stuff from other well known haunted sites and haunted
objects. the trick was to use the infrasound to create fear in the
visitors, and let their imagination do their work, eg: seeing
ghostly images in mist from dry ice, hearing voices from echo
rooms, as the visitors get nearer to the source of the infrasound,
the fear intensify, so no one actually got to know the secret.
