Subject: Affordable/simple audio hardware for psychoacoustic experiments? From: Daniel Oberfeld <oberfeld@xxxxxxxx> Date: Thu, 5 Jul 2007 09:58:05 +0200 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>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?
