Lucid Speaker

Lucid Speaker is set on the ceiling and

every person located near or far from the speaker can hear at same db.

■ Comparison with other kinds of speaker

1.  Lucid Speaker

   : Every person located with different distances can hear at same dB.

2.  Ceiling Speaker

   : Only person located just below Ceiling Speaker can hear properly.

3.  General Speaker attached on the wall

   : Persons located with different distances hear at different dB.

     In case of using test language ability, it would not be fair for everyone

     because persons located nearer can hear louder.
