Final answer:
The sound intensity level of the ultrasound used to pulverize tissue during surgery is approximately 95.0 dB.
Step-by-step explanation:
To calculate the sound intensity level in decibels (dB) for ultrasound with an intensity of 1.05 x 105 W/m2, you can use the formula:
Sound Intensity Level (dB) = 10 * log10(I/I0)
where I is the given intensity and I0 is the reference intensity, which is generally taken to be 1 x 10-12 W/m2 for sound in air.
Calculating this gives us a result of approximately 95.0 dB.
