Hello,

apparently there are certain low frequency bass sounds that make people
feel squeezy or irritated. Anyone know, where I might find those on the
net?

Make your own. Use an audio editor to halve the playback speed of your
favourite bassy tracks, or just to generate sine waves at 15 to 30Hz.

How would I do that? What programmes can I use that are shareware?
