Learning to listen

I must admit, this came as a shock to me but the implications could be profound. A brief scenario. Take a pair of the best headphones you can find and listen to them, now hand them to a friend and have him listen to the same audio you just heard. Suppose both people have excellent hearing. Does the audio sound the same to you and your friend. The answer is almost always "no". Now ask yourself, can something be done about this? The answer might just be "yes", at least according to David Griesinger a physicist/inventor with a passion for sound, music, and acoustics. Although I found all his videos informative, although rather technical, his video titled "Binaural hearing, Ear canals, and Headphones" was most convincing. I would also recommend another video titled "Learning to Listen", which might give the best overview of what his research has discovered.

Finally, his website has important information about his DGSonicFocus program which can help match your headphones and speakers. I don't use windows or Mac so I can't personally validate what the program will do but matching in this way should help improve the sound. This community's feedback will be very useful. Indeed, if it can be shown to work as claimed and we can get Modartt onboard, there may indeed be the implications I mentioned. Modartt may also hold the key (see the main website) to help get the program working on multiple platforms.
