This unit opens a whole new world allowing you to listen to sounds you didn't think even existed! Its directional reception allows for the detection and general location of ultrasound that may be used as harassment.
A crumpling plastic bag, moving coins, a key chain, rain drops, etc. It can serve as a detection device allowing one to hear animals or people walking in the woods on dry ground, or even on a wet day. Leaking air, water, gas, steam, pipes, and machinery wear are only a few of the many faults easily made detectable, potentially preventing more serious events from occurring. It has many uses, both in the scientific field especially entomology to study insects, bats, other animals and fauna.
Listen to the amazing world of high-frequency sounds. This unique item is a directional ultrasonic heterodyning type listening device. Included headsets may differ from those shown in picture. Determine what and where it is coming from!Ĭlick HERE for actual bat sounds recorded using the HT90 The ultrasonic generators are devices that create ultrasonic sound waves, which can be used in some novel ways such as a safety deterrent or conditioning device.Īdvanced Electronic Circuitry lets you hear only Ultrasounds and Reject Normal Sounds. The ultrasonic receiver is a device that can detect sound waves that are normally beyond the range of human hearing, and then translate this signal to audible frequencies. This page describes some very unique items generally categorized as "ultrasound"
