1A graph representing a sound, showing the distribution of energy at different frequencies.

- ‘Research using sonograms (device for visualizing sound), hydrophones, and other acoustical devices have shown that that these whales produce two sounds termed A or B calls.’
- ‘A link brings you to an informative introduction, followed by a list of six birds whose sounds are represented as sonograms and in musical notation.’
- ‘Cross-correlation coefficients computed from comparisons of sonograms reflect differences in the spectral and temporal characteristics of the call, as well as differences in signal-to-noise ratio.’
- ‘Since the researchers only hear and see the sounds as played back over a sonogram (a device for visualizing sounds), they're not certain as to which or how many whales are responsible for the calls they detect.’
2A visual image produced from an ultrasound examination.
- ‘A routine trip to DJ's doctor turned into a trip to the radiologist and x-rays and sonograms and all the stuff that comes with that.’
- ‘A sonogram uses sound waves to make pictures of organs in the body.’
- ‘Instead, he may use sound waves for a sonarlike mapping power that doesn't need x-rays - much as doctors use sound to create sonograms of unborn babies.’
- ‘The sonograms, which prognosticated a boy, were wrong.’
- ‘In contrast, a bilateral, solid, irregular, and fixed mass palpated or seen on sonogram should alert the clinician to a possible carcinoma.’
