Problem: Ultrasound waves at intensities above 104 W/m2 can do serious damage to living tissues. If 104 W/m2 corresponds to 160 dB, what is the sound intensity level, in decibels, of ultrasound with intensity 105 W/m2, used to pulverize tissue during surgery?

FREE Expert Solution

Sound intensity:

β=10 log (II0)

where I0 is the threshold intensity of hearing.

I0 = 1 × 10-12 W/m2
