Which adjustment would not increase acoustic exposure?

Explanation:
Acoustic exposure depends on the energy delivered by the ultrasound beam. If you increase transmit power, you push more energy per pulse, so exposure goes up. Frame averaging requires emitting multiple frames to form an image, so more pulses are sent over time and total exposure increases. Frequency, on the other hand, changes how sound propagates and is attenuated but does not raise the energy emitted per pulse if the drive conditions stay the same; it mainly affects penetration and resolution rather than the amount of energy delivered. So increasing frequency would not increase acoustic exposure.
