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?.

The ultrasound with intensity  10⁵ W/m², used to pulverize tissue during surgery, has the sound intensity level of 170 decibels.

The relation between sound intensity and sound intensity level is given by:

β (dB) = 10 x log(I/Io)

Where:

β = sound intensity level in decibels (dB)

I = sound intensity

Io = reference intensity

In the given problem:

β = 160 dB if I = 10⁴ W/m²

Find the reference intensity:

β = 10 x log(I/Io)

160 = 10 x log (10⁴ /Io)

log (10⁴ /Io) = 16

Io = 10⁻¹²

Use Io = 10⁻¹² to calculate the sound intensity level of  10⁵ W/m² sound intensity.

β = 10 x log(10⁵/10⁻¹²)

β = 10 x log(10¹⁷)

  = 170 dB

Hence, the sound intensity level is 170 dB
