Great
Sound at Europe`s biggest Live Sound Trade Fair
The annual ProLight + Sound trade fair (PLS) in Frankfurt
is acclaimed for Live sound demonstrations from top PA system
manufacturers. This year the “Agora Live Sound Arena”, in the middle
of the exhibition halls, was again a big attraction. While the
various manufacturers presented their large-scale PA systems and
latest stage equipment under realistic conditions at this open-air
venue, the acoustic engineering company AMT, Isernhagen was
responsible for protecting the public’s hearing according to the DIN
15905-5 standard. All sound level measurements were performed with
the XL2 Sound Level Meter and visualized on the rather big screen
using the Projector PRO software.
The Live Sound Arena was once again a crowd-puller this year.
There is no doubt that, within reason, “louder is better” in such a
comparative demonstration environment. AMT's job was to measure and
display the sound levels, as well as advise the exhibitors on what
is possible within the legal limits. For the sound level
measurement, AMT chose the XL2 Sound Level Meter, because it is
compliant, can integrate with the big screen, and provides a clear
traffic-light color warning system.
