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
