How It Works

The Hornet uses the LATEST MILITARY TECHNOLOGY to clear your way.

"Just want to say it's the first item of this type I've used that really seems to work. You have a great product."

– Jerry

The Hornet is your best protection against costly and deadly animal related accidents. Using the latest military technology from the field of high pitched, directional sonic bombardment, the Hornet's precision turned sonic generator alerts deer and other animals of your approach well before they can see or hear your vehicle. Proprietary wave variance tuning enables the sonic impulse to carry long distances. The Hornet is endorsed by major insurance companies and is used by police and emergency vehicles nationwide with millions of proven road miles. Proven effective at any speed, the Hornet is electronically powered and does not rely on wind or air flow.

The Hornet Deer Avoidance Device is a precision tuned sonic generator which produces a high pitched, directional sonic wave. When this wave is reflected from the road surface of a moving vehicle, a virtual sonic echo effect is produced. This sonic wave has proven its ability to alert deer and most other animals to approaching vehicles with sufficient warning to avoid costly accidents. 

The use of the Hornet, along with driver awareness, has been proven to reduce the risk of animal/vehicle collision by more than 70%. The electronically produced sonic wave is effective at any vehicle speed. The Hornet Deer Avoidance Device is your best protection from vehicle damage and deadly animal related accidents.


Technical Understanding

Most animals (mammals), including people, hear within the same basic frequency range, although there is a vast range of how various animals will react to The Hornet. The reason The Hornet works so well on deer is they have acute hearing and are very skittish animals with a strong sense of survival. When you are approaching deer with your vehicle, they will react to The Hornet by lifting their head to determine if they are being threatened. As your vehicle is moving towards the deer, they will normally run for safety.

With a basic understanding of acoustical engineering, the sound pressure (dB) push density physics of The Hornet and its unique Wave Variance Tuning ® method of sound packet delivery with reflected bounce will become clear.

The sound pressure level is defined as the difference between actual pressure (at a given point and a given time) in the medium and the average, or equilibrium, pressure of the medium at that location. A deer's ear can detect sound with a very wide range of amplitudes. Sound pressure is often measured as a level on a logarithmic decibel scale. The sound pressure level (SPL) or Lp is defined as...


...where p is the root-mean-square sound pressure and pref is a reference sound pressure. Commonly used reference sound pressures, defined in the standard ANSI S1.1-1994, are 20 µPa in air and 1 µPa in water. Without a specified reference sound pressure, a value expressed in decibels cannot represent a sound pressure level.
