Affordable/simple audio hardware for psychoacoustic experiments?
Dear list,
Just a brief introduction: I'm Lorenzo Picinali, I work at LIMSI (CNRS, Orsay, France) and I'm a Phd student at the DMU (Music, Technology and Innovation Research Centre, Leicester, UK) on research themes liked to the spatial perception of sounds and to the simulation of three dimensional soundscapes through headphones or loudspeakers array.
About the audio hardware for psychoacoustic experiments, if you want to use the onboard sound interface (it might not be an high quality one, but for restricted budget, it might be ok), I'd suggest to connect the stereo line output to a multichannel headphones amplifier such as a Samson one (the best you can get for that price...) or a Presonus one (a bit more expensive).
While, if you want to buy an external audio interface, I'd suggest an ECHO one (PCMCIA) or a M-Audio or Edirol (USB): they are not really high quality ones, but they do their job! Then, of course, if you want to drive more than a pair of headphones, you need an headphones amplifier (as I was saying before).
Best Regards
Lorenzo Picinali

Subject: Affordable/simple audio hardware for psychoacoustic experiments?
Dear list,
in some of our undergraduate labs in Experimental Psychology, the
students conduct simple psychoacoustic experiments like measuring a
detection or a discrimination threshold.
To reduce the blocking of our laboratories by these courses, we want to
purchase a simple computer setup (Matlab-based) on which the students'
experiments can be run.
The most simple and most cost effective solution would be to connect the
headphones (e.g. Sennheiser HDA200, which give you some sound insulation
even outside a sound-insulated chamber) directly to the soundcard/
digital-to-analog converter. Does anybody here have experience with such
a setup and could recommend a device with low noise but sufficient
output power to drive low-impendance headphones? A stereo device would
do, but four or more audio channels would be preferable.
Or alternatively, do you know an affordable (i.e., non-TDT) low-noise
headphone amplifier you could recommend?
Kind regards,
Daniel

Having seen age discrimination in EU-funded projects as well, it seems
to
me that age discrimination is legal in Europe. Probably they think that
it
is a positive discrimination?

Subject: Listening Test Speech Data
Dear List,
As the topic is fresh now may be a good time to request some information
on this area.
Im looking for some reasonably recent wideband speech databases that
would be suitable to test with the PEAQ algorithm. Really, Im looking
for speech files with a reference speech file and a degraded version of
the reference speech file. It is preferrable to have known subjective
data on such speech files also. Any help appreciated.
Thanks,
Dermot.

Subject: post-doctoral position in auditory cognition
Post-doctoral position: auditory cognition in nonhuman primates
A postdoctoral position is available to study the neural basis of
auditory cognition in nonhuman primates. The focus of the
laboratory is on how our brains represent features of communication signals,
especially higher-order features. Our main technique is single-unit recording
in awake animals performing behavioral tasks.
Behavioral analyses and computational modeling also consitute an
important component of our work. Suitable backgrounds include vision,
audition, oculomotor, or other areas of systems neuroscience.
Experience with electrophysiological recording and skills in
quantitative analysis and programming are a plus. Send CV and names
of 2-3 references to Dr. Yale E. Cohen, 6207 Moore Hall, Dept. of
Psychological and Brain Sciences, Dartmouth, Hanover, NH 03755,

Hi everbody,
I am wondering if there is a PC-based program for running an adaptive
paradigm. We do not have the hardware, so will have to route the signal
through the sound card. Any ideas? The stimuli will be speech and
speech-shaped noise. Any feedback will be appreciated.
Thanks,
Vidya
