Re: Free software for conducting psychoacoustic experiments
By popular demand here are the replies to my question
Great thanks to everyone for their suggestions. I will test drive them this semester and report on them at the end.

there is! it is MLP! I know it is matlab based. But your students do not need to program it to set the experiments. I used it with my student this yes (undergraduate with no programming experience) and it was ok.

There is one software called APEX developed at the kuleuven. You can download it for free and the only condition to use it is to mention in publications when it is used. It allows to perform psychoacoustic experiments and also it works with cochlear implants.

Praat (www.praat.org) does a lot, including run some simiple experiments
(ID and Discrimination). Although mainly geared toward speech, it has a
fully functional capability of creating sound by equation. More
importantly, it's scriptable, so you can in principle get it to do
almost anything.
Hope this helps,

Dear Fatima,
I conducted some experiments in 2002 with MEDS (http://www.ethnomusic.ucla.edu/systematic/Faculty/Kendall/meds.htm).
It had some bugs at that time, but it was a useful initiative from Prof. Kendall, who provided me some support.
If your students are patient and open to a more "computer music" approach they may want to learn PD (Pure Data - http://puredata.info/). The learning curve is not so comfortable but the media possibilities of PD (manipulation of audio, video and sensor data in real time) open nice possibilities to develop interactive experiments. Interactive setups are sometimes useful to develop effective experimental setups and decrease the duration of the experimental sessions.
Best,
Luiz Naveda

I use the Auditory Interactivities program from Sensimetrics. It is not
free, but not terribly expensive, and works pretty well for most things.

Dear Fatima,
I have made a psychoacoustic testing tool available at:
http://www.sens.com/percept/
I use the tool specifically for training and tracking performance of cochlear implant users, hence the emphasis of the download site. But all of the activities included are just as useful for normal hearing listeners, except for the one that uses piano notes as it tends to be too easy for the normals. Included activities are: forward and backward masking, tone in noise detection, gap detection, various frequency difference limens tests, vowel perception in noise, and some binaural activities.
You can also access the guts of the utility to design more elaborate tests. In fact, if you have the appropriate hardware and permissions, you can use the utility to design and implement novel psychoelectric and sound processing design experiments with cochlear implantees. Or perhaps more useful for instruction, you can visually analyze and create cochlear implant acoustic simulations from all of the listening activities.
In the current form, since I am interested in tracking data, the utility saves information (excluding names of the people taking the activities) back to Sensimetrics. Please let me know if you have any trouble installing and running the tests, or if you have any questions.
cheers,
