[PD] dbtorms amplitude scaling sounds wrong

Hi list,

I'm using dbtorms for amplitude control as follows:

 signal in  volume (0 to 100dB)
         |  |
         | [dbtorms]
         |  |
         | [$1 50<
         |  |
         | [line~]
         | /

This is AFAIK the correct way to use it. The problem
is, the amplitude scaling doesn't sound right to my
ears. 100dB is the loudest and 0dB is silence all
right, but 50dB is extremely quiet. I thought that dB
in this case are supposed to represent 'loudness', so
50dB should sound half as loud as 100dB? To me
'halfway' seems to be somewhere between 80dB and 85dB.
Is it my patch or my ears?
