354808 Which of the following has high pitch in their sound

1 Mosquito
2 Lion
3 Woman
4 Man
PHXI15:WAVES

354809 There are 10 sound sources each producing intensity \(I\) at a point independently. They are incoherent. Average intensity of sound at that point will be

1 10 \(I\)
2 625 \(I\)
3 \(I\)
4 100 \(I\)
PHXI15:WAVES

354810 The persistance of sound in a hall is called

1 Resonance
2 Reverberation
3 Articulation
4 Acoustics
PHXI15:WAVES

354811 A person speaking normally produces a sound intensity of \(40\;dB\) at a distance of \(1\;m\). If the threshold intensity for reasonable audibility is \(20\,dB\), the maximum distance at which he can be heard clearly is

1 \(5\;m\)
2 \(4\;m\)
3 \(20\;m\)
4 \(10\;m\)
