suppose that the sound level of a comversation is initially at an angry 70 dB and then drops to a soothing 53 dB. Assuming that the frequency of the sound is 521 Hz, determine the a) initial and b) final sound intensities and the c)initial and d) final sound vave amplitudes. Assume the soeed of sound in 343 m/s and the air density js 1.21 kg/meters cubed.

Suppose that the sound level of a conversation is initially at an angry 73 dB and then drops to a soothing 51 dB. Assuming that the frequency of the sound is 524 Hz, determine the (a) initial and (b) final sound intensities and the (c) initial and (d) final sound wave amplitudes. Assume the speed of sound is 345 m/s and the air density is 1.21 kg/m3.

When we are angry, we unconsciously increase the intensity of the sound we emit. In a soap opera, the cast is acting angry with each other with a level of 79 dB, then they make up so that the sound output becomes 57 dB. The frequency of their sound is 337 Hz, the velocity of sound in the air is 344 m / s and the density of the air is 1.21 kg / m3. What is the sound intensity...
