A measure of noise in France
October 1st 2008 There are many reasons for
investing in noise
measurement equipment,
usually due to legal
necessity. However Pulsar
Instruments was delighted
to assist Sky 1's Brainiac:
Science Abuse team in an
effort to determine whether
sound could travel from
England to France.
The experiment involved
Vic Reeves in England
making a series of loud
noises and Jon Tickle
attempting to measure the
noises in France.
The Brainiac: Science
Abuse team used a Pulsar
Model 33 to perform a 1:1
octave band analysis
measurement to determine
whether sound would make
the 22.1 mile journey across
the English Channel. Having
tried their usual trademark
explosions on the ground
and 6 salute shells in the air
with no success, the
solution came in creating a
wall of tonal noise at 50Hz
using a speaker stack, which
was then measured 1 minute
44 seconds later in France.
The Model 33 is suitable
for most applications,
including noise at work
assessments, noise control,
accurate hearing protection
prescription, room acoustics
and environmental noise. More articles from Pulsar Instruments Plc: |
