Ultrasonic Leak Detector
ULD-420
-
When equipment begins to fail due to an air or gas leak or vibration, or electrical discharge, the leakage point emits an ultrasonic sound wave that is above the natural range of human hearing. The ULD-420 Ultrasonic Leak Detector converts this ultrasonic sound into a signal that can be used to pinpoint the exact location of the equipment failure. When working in unpressurized systems or the pressure is not sufficient enough to detect or verify a leak with the Receiver alone use the Transmitter.

NeuroSensory Analyzer
TSA-II
-
TSA thermal stimulator test procedure The test procedure itself is similar to that employed in such routine tests as eye and hearing examinations, where patients are asked to respond to visual or auditory stimuli. Sensory testing is performed by applying the TSA-II thermode on the patient's skin to heat or cool the skin. Patients respond to the temperature stimuli by pushing a button, and the sensory threshold is recorded and automatically compared to an age-matched normative data.

Manikins for realistic simulation of the acoustic properties of a human
Head & Torso Simulators
-
If you need to carry out realistic in-situ measurements of headphones, telephones or hearing aids, you need a Head and Torso Simulator such as the B&K ‘HATS’ – Type 4128D or GRAS’ Kemar to complete your test setup. These manikins have built-in ear and mouth simulators that provide a realistic reproduction of the acoustic properties of an average adult human head and torso. They are commonly used for tests on telephone handsets, headsets, audio conference devices, microphones, headphones, hearing aids and hearing protectors. Please contact your sales engineer or email sales@listeninc.com for more information.

ELT STALKER Vector-finder
VF-121
-
The Vector-Finder Types VF-121 and VF 121A are unique in the Vector-finder series of direction finding antennas. They incorporate a proven design, electro statically shielded loop sensing element with modern solid state low noise analog and digital technology to allow detection and location of aircraft band signals. Both the VF-121 and the VF 121A incorporate a unique digital modulator which allows the user to more easily home-in on unmodulated carriers. Such cases occur at airports when transmitter may be accidentally keyed on during aircraft overnight layovers. The VF-121 is specifically designed to be used on airport premises where signal strengths are high. To compensate for very strong signals, an integral attenuator is also incorporated to allow the user to operate the unit close-in to aircraft. The VF-121A differs in that a high gain, low-noise preamplifier is utilized with the sensing element in order to hunt signals that may be weak or at a distance. The unit is ideally suited for the location of ELT transmitters in the field. Both units are tunable over the 118 MHz to 130 MHz aircraft frequencies and interface directly to the user’s aircraft band receiver or transceiver via the antenna jack. With the antenna system connected to the receiver, the user will hear the desired signal. If the signal is unmodulated, the digital modulator will generate a tone on the carrier. When the handheld unit is rotated about, an audible null on the received signal or the generated tone will be heard. This null aligns with the axis of the equipment case and represents the direction of the received signal. This direction may be read from the black dial compass mounted on the top of the enclosure. As the response is bi-directional, triangulation may be used to determine the true bearing when the true direction is not known.

Sound Quality Evaluation Function for O-Solution
OS-0525
-
The sounds generated from the equipment are mainly measured by evaluation based on general analysis such as sound pressure level, FFT analysis and 1/3 Octave analysis. However, since those analysis don’t take into consideration the human hearing characteristics enough, sounds with even the same analysis result may give different impression.When a human listens to a sound, various sensations such as loudness, sharpness, and roughness occur.
