Medical scan using sound waves
A medical test where doctors use sound waves to see inside your body, for example to look at a baby during pregnancy or to check an organ.
รูปแบบการใช้:
to have [an ultrasound] (on [a body part])
ข้อผิดพลาดที่พบบ่อย:
Learners sometimes confuse “ultrasound” and “sonogram.” In everyday English, “ultrasound” usually means the test, while “sonogram” is the image from the test. Learners also sometimes forget the article and say “I have ultrasound tomorrow”; in this medical sense, it is usually countable: “I have an ultrasound tomorrow.”

Sound waves above hearing range
Very high sound waves that people cannot hear, used in medical tests and some machines.
รูปแบบการใช้:
ultrasound is used for [a purpose]
ข้อผิดพลาดที่พบบ่อย:
Learners sometimes think “ultrasound” means “very loud sound.” It actually refers to very high frequency sound, not to volume. There is also confusion between the noun “ultrasound” (the type of sound) and the adjective “ultrasonic” (describing devices or waves that use ultrasound).
คำพ้องความหมาย
ultrasonic sound (More explicit technical phrase; slightly longer and less common in everyday medical language.)
คำตรงข้าม
infrasound (Refers to sound waves with frequencies below the human hearing range, in contrast to ultrasound which is above it.)
