Clear and loud sound can only be heard at seating positions P and Q which is equals to 4 seatings away from each other with a certain distance from the loudspeakers. When the technician moves further away from the loudspeakers, the clear and loud sound can only be heard between Q and R which is equals to 6 seatings away from each other.
