If the intensity loss along the beam path from point A to point B is 5 dB and the intensity loss along the beam path from point B to point C is 2 dB, what is the intensity loo along the beam path from point A to point C?
The sound intensity level (β) corresponding to a sound intensity (I) and a reference sound intensity (I0) can be expressed in dB as follows:
Let IA, IB, and IC, and βA, βB, and βC denote the sound intensities and the sound intensity levels at the given points A, B, and C, respectively.
Determine the intensity loss expressions (βA – βB, βB – βC, and βA – βC) from the above expression as follows:

- High-intensity focused ultrasound (HIFU) is one treatment for certain types of cancer. During the procedure, a narrow beam of high-intensity ultrasound is focused on the tumor, raising its temperature to nearly 90 °C and killing it. A range of frequencies and intensities can be used, but in one treatment a beam of frequency 3.10 MHz produced an intensity of 1425.0 W/cm². The energy was delivered in short pulses for a total time of 2.60 s over an area measuring 1.20 mm by 5.30 mm. The speed of sound in the soft tissue was 1570 m/s, and the density of that tissue was 1492.0 kg/m³. What was the wavelength of the ultrasound beam?
