hard of hearing & tv too loud

[encephalopathy]

my dad is having probs with his hearing in one ear
the result is that he turns the tv up to earbashing volume levels for the rest of us

i am thinking of an av amp and 5.1 with the rear speakers either side of where he usually sits, balanced so the volume on the deafer side is higher

tv is 26inch crt with sky box and dvd player connected

any [sensible] alternatives

thanks

thought about headphones but then no-one else would hear the tv at all

the hearing aid is probably the simplest answer - he just is too stubborn to use it
