Ultrasonic Vocalization Software

Summary

---

• Samples ultrasonic frequencies every 30 milliseconds and differentiates between two user-defined bandwidths
• Med-PC^® can be used in conjunction with the USV detector to turn on the detector, and correlate events such as food or shock delivery with the data acquisition
• Use with up to 16 devices
• Software has graphing utilities for:
  • Spectrograms (KHz x Time x dB)
  • Sonograms (KHz x Time)
• Text data file includes a vocalization’s:
  • Time of onset
  • Duration
  • Quantity (in each band)

Data Collection Options

---

Low: (20-100 kHz) Vocalizations at frequencies below this cut-off value will be disregarded

High: (20-100 kHz) Vocalizations at frequencies above this cut-off value will be disregarded

Threshold: (10-150 dB) Vocalizations must occur at an amplitude greater than this value in ordered to be recorded by the software.

Band 1: The first frequency range of interest

Band 2: The second frequency range of interest

NOTE 1: To represent the data as a cumulative or event plot, use in conjunction with Med-PC^® and SoftCR Cumulative Recorder (SOF-721) software.

USV Occurrences

The USV data illustrates the onset and duration of vocalizations occurring within two user-defined frequency bands above an amplitude threshold.

 

Cumulative Record

Data can be viewed as an event plot or in a cumulative fashion to represent the rate of USV occurrences as a method of estimating the rate of USV occurrences. Each occurrence of an ultrasonic vocalization causes an increase on Med-PC^®’s SoftCR Pro® cumulative plot.

 

Sonogram

Graphs USV occurrences (in kHz) over time, providing information on the duration and frequency of a USV, as well as relative changes in pitch.

 

Spectrogram

A three-dimensional surface plot that illustrates frequency (in kHz) by time and amplitude (in dB). Particularly useful for revealing ultrasonic artifacts in the testing environment, such as ultrasonic vibrations created by some fluorescent lamps or computer monitors. Once artifacts are recognized, the bandwidth can be adjusted to isolate USVs from other ultrasonic events.
