Hi,

I have a problem when using pink noise as the input signal, using speakers from the 'human' folder (eg MANNORM, FEMRAISED, etc) results in the speaker power being exceeded for the appropriate SPL at 1m in each 1/3 octave band.

Setting "all to max" results in a much lower SPL than expected for human voice level.

Please let me know if there is any way to solve this.

Hi Nick,

what do you get and what do you expect?

Hi Nick,
the speechlevel of the ease-humans are at least on the low end of the range you can find in lterature or even lower.
(e.g. EASE-mannorm: 48,7 dB(A)/1m, literature, normal speech: (55..60) dB(A)/1m)

You can change the Max Power setting for each 1/3octave in the ease speaker base (Edit/Speaker Data). If you change all bands in the same way (same factor), the spectrum remains the same. I would change the name and the file as well.

Hi Frank,

EASE has the following max SPL @1m for human speakers, limited by speaker power

Man normal - 48.7 dBA
Man raised - 54.9 dBA
Fem normal - 45.7 dBA
Fem Raised - 53.4 dBA

Typically I would expect 55-60 dBA for normal speech and 65-70 dBA for raised speech so the EASE data is very low as Thomas has pointed out.

Thanks for your help with this btw Thomas, I will give that a try.
