[Sound waves get reflected from the walls and toof of a room multiple times. This causes a single sound to be heard not once bur continously. This is called reverberotion? The time between successive reffections of particular soundwave reaching us becomes smaller and the reflected sounds get mixed up and produce a continuous sound of increased loudness which connot be deciphered clearly. This is the reason why some auditoriums or some particular seats in an auditorium have inferior sound reception. This is shown in figure 12.3 Reverberofion Use your brain power! How will you reduce reverberation in public hall or buildings? 【SONAR is the short fom for Sound Navigation and Ranging. It is used to determine the direction, distance and speed of an underwater object with the help of ultrasonic sound waves. SONAR has a transmities and a receiver. which are fitted on ships or The produces and transmitter ultrasonic sound waves.] [These waves travel throughi water, strike underwater objects and get reflected by them. The reflected waves are received by the receiver on the ship.] The receiver converts the ultrasonic sound into elecirical signals and these ignals or properly interpreted. The time difference between transmission and reception is noter This time and the velocity of sound in water give the distance from the ship, of the objec which reflects the waves?
