Acoustics

a time-frequency image of a sound

In acoustics, a sonogram (spectrogram, sonagram, 'voiceprint') is a picture of a sound with time on one axis, frequency on the other, and intensity shown as darkness or color. It became practical with the sound spectrograph of Koenig, Dunn, and Lacy (1946) and is standard for speech and birdsong analysis. This is an image of airborne sound, distinguishing it from the medical sonogram, an image of body tissue.[1]

Unit
One time-frequency plot of a sound
Recovery means
Run a recorded sound through a short-time Fourier transform and display magnitude over time and frequency.
Measured by
Short-time Fourier / filter-bank analysis producing a 2-D intensity map.

Medicine

an image of body tissue made from reflected ultrasound

In medicine, a sonogram is the image produced by diagnostic ultrasonography: pulses of high-frequency sound are sent into the body and their echoes are reconstructed into a picture of tissue. Donald, MacVicar, and Brown (1958), in The Lancet, pioneered pulsed-ultrasound imaging of abdominal masses. The referent is an echo map of internal anatomy, not a spectrogram of airborne sound.[2]

Unit
One ultrasound image of tissue
Recovery means
Scan tissue with an ultrasound transducer and reconstruct echo returns into a cross-sectional image.
Measured by
Pulse-echo timing and amplitude of reflected ultrasound converted to brightness.
