A good pink noise generator and a
spectrum analyser are indispensable if you
want to analyse the acoustic properties of
a room (usually a living room).
• Moreover, you also need a microphone
with a frequency characteristic that is
as linear as possible (from 20Hz to
20kHz).
• If you have an equaliser, then the
response can not only be checked but
also corrected.
• The kit is easily adapted to produce
“white noise”.
Great little gadget for service, repair, testing, education,
etc...
