FOUR Powerful 115dB Air ULTRASONIC TRANSDUCERS.

This is a FOURPACK  of our medium power ULTRASONIC AIR TRANSDUCERS. Each transducer has plastic body, is Waterproof and is about 3" big. Frequency range is 4kHz - 23kHz, and it can be powered directly from any extended Audio Power Amp such as our 240W Amplifier, or our 100W Ultrasound Generator, Dog Bark Deterrent or Sonic Nausea device. 
Produces up to 115dB Sound Power at frequencies below 10kHz, and is most effective up to 20kHz, with lower output at frequencies above that. Is more powerful than our 100W Air transducer and can be attached to our Long Range 10" horn, using an adapter (sold separately).

Can be used for experimenting with ultrasound and as a Phasor pain field generator (by continuously sweeping frequency). That can be triggered by a trip wire or other sensor, and used as a security system to repel two or four-legged trespassers. Sweeping ultrasound can cause certain adverse effects like paranoia, severe headaches, disorientation, nausea, cranial pain, upset stomach, or just plain irritating discomfort. Great for animal control. Frequencies below 21khz affect humans, and above 21khz are for animal control.

Our 100W Ultrasound Generator will handle up to FIVE of these transducers connected in parallel.
