44.3.3 High efficiency alarm tones
Four different high-efficiency alarm tones are on the
distribution DVD in the folder \Tools\Audio Tools and
Sounds\High efficiency alarm tones. Because the tones are
too complex to be generated in real time as start tone or
end tone by the Praesideo system, these tones are
designed as special multi-sine wav-files and should be
used as messages in a call macro.
The tones are perceptually very loud and still have a
limited RMS value of -6 dBFS, so they can be played
back continuously without overheating the amplifiers.
Also power consumption of the amplifiers will be
reduced by 50% compared to normal sine alarm tones,
that are scaled to -3 dBFS in Praesideo. However,
although these high efficiency tones sound much louder
than normal sine waves, a dBSPL measurement will not
show this. This is because a normal dBSPL
measurement does not take the applied psycho-acoustic
factors into account. The high efficiency alarm tones are
particularly useful for situations with much background
noise, where a normal sine wave would be easily
masked
