Is the amplitude of a sound wave adjustable?

The amplitude of a sound wave is indeed adjustable, which is why this answer is correct. In sonography, the amplitude refers to the maximum displacement of particles in the medium through which the sound wave travels. Adjusting the amplitude directly affects the strength of the sound wave, which in turn influences the brightness of the echo or the intensity of the ultrasound image.

Ultrasound machines are designed with the capability to modify the amplitude of the emitted sound waves. This adjustment can help optimize imaging parameters for different patients and clinical situations. A higher amplitude results in stronger echoes, improving the overall image quality, while a lower amplitude might be used to reduce patient discomfort or avoid overexposure.

While other answers may present valid concepts, they do not accurately capture the fundamental operational aspects of amplitude adjustment in sonography. The ability to control amplitude is a significant feature of ultrasound technology that enhances the versatility and effectiveness of imaging techniques.
