Two loudspeakers are arranged facing each other at some distance. Will a person standing behind one of the loudspeakers clearly hear the sound of the other loudspeaker or the clarity will be seriously damaged because of the 'collision' of the two sounds in between ?

Two aeroplanes are moving towards each other. One of them blows a horn the person in the other plane hears the sound. The apparent pitch will

Two sirens at a distance apart are soundings with the same frequency, when a person standing between them runs towards one siren then he hears beats, Why?

If you clap on one end of a long steel pipe you will hear two distinct sounds on the other end of the pipe. Explain.

Two identical loudspeakers are placed on a line at distance 4m and 6m from a microphone lying on the line joining them. The output of each speaker at the microphone is 2mW . If the two speakers are connected in series and excited by the same oscillator and they vibrate in phase with each other, the resultant ouput of the microphone will be (frequency of oscillator =660 Hz and speed of sound =330 m//s )

'The person standing behind the open door inside the room can hear the voice of this person standing on the other side of the door but they cannot see each other". Give experiment based on the diffraction for this statement.

Two junglemen are standing at the two opposite banks of a river of width l facing each other. One of the m starts beating a drum and sound reaches to the other one after time t_(1) the stats. Then second one starts beating the drum and now first one hear the sound after time t_(2) . Calculate the velocity of sound relative to air and the velocity of wind, if it is blowing from first bank to the other bank at right angle to the river flow

A steel tube of length 1.00 m is struck at one end. A person with his ear close to the other end hears the sound of the blow twice one travelling through the body of the tube and the other through the air in the tube. Find the time gap between the two hearings.
