Temperature source (2.11.1.4.) (Page 219)
Enter the temperature of the atmosphere within the transducer acoustic beam. If the
temperature varies with distance from the transducer, enter the average temperature.
Sound velocity at 20°C (2.11.1.7.)
This value is used to automatically calculate Sound Velocity (2.11.1.2.) (Page 218).

Check this value to verify the acoustic beam atmosphere is air (344.1 m/s or 1129 ft/s) after
performing a Sound Velocity Calibration (for the procedures, see Using Sound Velocity
Calibration (Page 221) below) .
Alternatively, if the acoustic beam atmosphere Sound Velocity at 20°C (68 °F) is known, and
the sound velocity vs. temperature characteristics are similar to that of air, enter the sound
velocity. The units are in m/s if Units (2.1.1.) (Page 162) = meters, centimeters, or
millimeters; if Units (2.1.1.) (Page 162) = feet or inches, then they are in ft/s).
