In a sound wave, to increase the intensity by a factor of 10, pressure amplitude must be changed by a factor of

The sound level at a point is increased by 30 dB. What is factor is the pressure amplitude increased?

The sound level at a point is increased by 30 dB. What is factor is the pressure amplitude increased?

Two sound waves one in air and the other in fresh water are equal in intensity. (a) Find the ratio of pressure amplitude of the wave in water to that of the wave in air. (b) If the pressure amplitudes of the waves are equal then what will be the ratio of the intensities of the waves. [ V_(sound) = 340 m//s in air & density of air = 1.25 kg//m^(3), V_(sound) = 1530 m//s in water, density of water = 1000 kg//m^(3) ]
