Why choose UltraVox XT

If you are considering UltraVox XT, this information might help you make your decision. 

Strong basis – research examples

Although UltraVox XT 3 is a completely new software tool, it builds on knowledge and experience we have gained since the first version of UltraVox was released in 1995. Here are some examples of research that used UltraVox:

Kurejova (2010) found that ultrasonic vocalizations could indicate ongoing pain (such as bone tumor induced pain and neuropathic pain) – they closely paralleled the time frame of mechanical allodynia. The USVs increased over time in bone marrow cancer model mice, just like the pain. The scientists concluded that ultrasonic vocalizations are a reliable objective measurable parameter for ongoing pain. 

Dagyte (2009) measured 22 kHz vocalizations of rats during a 20 minute foot-shock test, and found that the rats vocalized at that frequency (widely associated with negative emotions, pain, anxiety) at exposure to the shock, over the complete duration of the test. Over the 3 week course of the protocol the rats did not show habituation in terms of their vocalizations.

Why UltraVox XT?

There are several reasons why it is time for UltraVox XT. You can now use technology that allows for a compact and cost-effective microphone that captures the full acoustic spectrum. This means you don’t have to record in a specific frequency band, and you don’t need to use several microphones if you are interested in more than one frequency. The power of selecting and analyzing calls now lies within the software tool. You can easily detect calls by selecting amplitudes, frequency ranges, durations, and time gaps, or simply by dragging a box around the call in the spectrogram, and UltraVox XT will find similar calls. Then you can label individual calls (e.g. chevron, flat, upward) for further analysis. 

A wide range of applications

Access to the full acoustic spectrum means that UltraVox XT is useful not only for rodent studies, but for essentially any type of vocalization. Farm animal welfare studies and Precision Livestock Farming are two fields in which this program may prove especially handy.

A valuable behavioral parameter

Vocalizations and the specifics of the calls an animal emits, add another dimension to behavioral observations. Many studies can benefit from the combination of parameters to get full insight into the animal’s behavior. For that reason, UltraVox XT is designed to give you  export-ready data for compatible programs such as EthoVision XT and The Observer XT, and for use in other (statistical) packages. 

Local support and expertise

In 1995, the first version of UltraVox became available. This means that there is more than two decades of knowledge, experience, and research: a strong basis to build UltraVox XT 3 on.
