New from Campbell Associates, the
Norsonic 848 Acoustic Camera is
designed to to easily visualise sound.

The system uses an array of 225
microphones to provide high
resolution of the noise climate being
analysed.

Quick and easy to set up and use
without training or experience, the
system features a wide angle, highperformance
video camera.

Overall, 1/1-octave, 1/3-octave and
FFT can be measured for detailed
analysis. There are selectable upper
and lower frequency limits, while
colour intensity plots can be based
on level or frequency. A ‘virtual
microphone’ makes it possible to
listen to any part of the image in
isolation.

Analogue to digital conversion
electronics are hidden in the
microphone antenna, instead of a
signal analysis interface box, and
there is a LAN-cable connection
between the microphone array and
the supplied MacBook Pro
computer. The user friendly software
has all required functions for overall
and detailed analysis of complex
noise situations.

Applications include sound source
identification, acoustic leaks and
product design.
