sonogram

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.

A 'sonogram' uses sound waves to make pictures of organs in the body.

In contrast, a bilateral, solid, irregular, and fixed mass palpated or seen on 'sonogram' should alert the clinician to a possible carcinoma.

The 'sonograms' , which prognosticated a boy, were wrong.

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.

After amassing a collection of 'sonograms' , scientists can build a dictionary of sounds and search for patterns.

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 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.

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.
