I'm hearing impaired (high frequency hearing loss, the most common type) and was disappointed that HP Pavilion did not have an IR (infrared) system set up so I could hear the music more clearly.

I hope that those with hearing handicaps are accommodated for at future solo concerts. An IR system would have allowed me to use my induction loop (which I did bring) so that I could hear the performance undistorted.read more »
