Decide the sentences True or False: A lot of people play their record as loudly as possible. The result is that the rest of the family or the neighbors often complain if they don’t like the music. One answer to this problem is to wear headphones, but headphones are usually uncomfortable.
An armchair which has a record-player system built into it has just been designed by a British engineer, Stephen Court.
The armchair looks like an ordinary armchair with a high back. However, each of the two sides of the chair has three loudspeakers inside to produce middle and high sounds. Low sounds are reproduced by a pair of loudspeakers in a hollow space under the seat. Anyone who sits in the chair hears sounds coming from all round his or her head.
Because we cannot tell the exact source from which loud sounds come, it doesn’t matter that they come from underneath or behind. It is the higher sounds coming from the sides of the chair that create a stereo effect.
These sounds travel only a few inches to reach the listener’s ears. Consequently, it takes only a little power to make the music sound very loud. Only a small amount of sound leaks from behind the chair into the room to disturb others. Most of the sound is absorbed by the listener.

25. Stephen Court has just invented an armchair which can play music.
26. The armchair has very comfortable headphones attached to it.
27. Most people can tell exactly the direction from where low sounds are coming.
28. People sitting in chairs near the armchair will not be able to hear most of the sound.
