The Sonic Explorer is a listening device designed to listen in on the sounds of nature. This amazing detector picks up sound that is normally inaudible to the human ear. Tune your Sonic Explorer into the hidden sounds that surround us such as combing hair, fluorescent lights, rattling keys, tearing paper, rubbing fabric, and of course bats.
What is a Sonic Explorer?
This type of gadgets is divided into three broad categories: transmitters, receivers and transceivers. Transmitters convert electrical signals into ultrasound, receivers convert ultrasound into electrical signals, and transceivers can both transmit and receive ultrasound.
In a similar way to radar and sonar, ultrasonic transducers are used in systems which evaluate targets by interpreting the reflected signals. For example, by measuring the time between sending a signal and receiving an echo the distance of an object can be calculated. Passive ultrasonic sensors are basically microphones that detect ultrasonic noise that is present under certain conditions.
