Question about ultrasound
The whole point of my idea was that no equipment is needed by the user. its
well known that these devices need to be recharged and ones in cinemas are
often not working etc, so from my point of view, if you could beam it to the
person then it might be easier. Brian

Listeners wear lightweight, battery powered headphones fitted with a
sensitive IR detector, FM demodulator and audio amplifier. Sennheiser
made and still make systems like this intended for "assisted hearing"
or
language translation for audience members.
Probably quite annoying if the audience is watching a 3D film using LCD
shutter glasses though ...
** Who said IR phones were useful in cinemas ?
My post specifically mentioned halls, auditoriums and live theatre
productions - where they cater mainly older members of the audience who
may find themselves seated near the back and unable to follow dialogue.
