Ultrasound waves at intensities above 104 W/m2 can do serious damage to living tissues. a) 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? β =

Answer :

Ultrasound waves at intensities above 104 W/m² can do serious damage to living tissues,  104 W/m² corresponds to 160 dB, 170 dB is the sound intensity level, in decibels, of ultrasound with intensity 105 W/m²,

What is ultrasound waves?

An ultrasonic scan employs high-frequency sound waves to generate a picture of a person's interior body components. Ultrasound is frequently used by medical professionals to examine a growing foetus (unborn child), a person's abdominal and pelvic organs, muscles, tendons, heart, and blood vessels.

Given that,

Ultrasound waves at intensities above 10⁴ W/m² corresponds to 160 dB.

ultrasound with intensity 10⁵ W/m².

Sound intensity levels in dB is defined as:

β = 10 log [tex](\frac{I}{I_0})[/tex]

where [tex]I_0[/tex] is the reference intensity levels.

so, β₁ - β₂ = 10 log [tex](\frac{I_1}{I_0})[/tex] - 10 log [tex](\frac{I_2}{I_0})[/tex]

or, β₁ - β₂ = 10 log [tex](\frac{I_1}{I_2})[/tex]

or, β₁  = β₂ + 10 log [tex](\frac{I_1}{I_2})[/tex]

so, for β₂ = 160 dB, I₂ = 10⁴ W/m² , I₁ = 10⁵ W/m²

or, β₁  = β₂ + 10 log [tex](\frac{10^4}{10^5})[/tex]

or,  β₁  = 160 + 10 log [tex](\frac{10^4}{10^5})[/tex]

or, β₁  = 170 dB.

Thus, the sound intensity level is: 170 dB.
