Re: Gaussian vs. uniform noise audibility
I hereby retract my claims of 26 Jan 2004 regarding the audibility
of Gaussian noise at low standard deviations. As Dr. Nelkin has
kindly (and patiently!) pointed out to me off-list, the SD can have no
possible effect other than an apparent loudness change. My observation
of a qualitative difference at SD = 0.1 was due to a faulty algorithm.
I should like to stress that the discrepancy was due to the low-SD tails
not tapering off properly. Please do not rely upon DaqGen at SD much
below 1.0 until I have corrected the algorithm and notified the list.
My main finding is unchanged: There was no qualitative difference
between a uniform distribution and a Gaussian distribution.
Sorry of any confusion this has caused, and a hearty thanks to Dr. Nelkin
for his astuteness and his perseverance in resolving this.
