Eckel Noise Control Technologies
Anechoic Chambers are echo-free enclosures with a sound energy absorption level of 99% to 100%, or a reflected sound pressure level of 10% or less. The frequency at which the energy absorption drops below 99%, or the pressure reflection exceeds 10%, is known as the low-frequency cut-off. Sound absorption is obtained by lining the walls, ceilings, and floor with wedges or other sound absorbing elements or SuperSoft panels, depending on performance level required and cut-off desired.

VPE - Superior Signal Company
The Patented Superior AccuTrak VPE represents state-of-the-art technology for pinpointing leaks is air conditioning and refrigeration systems. AccuTrak is extremely sensitive to the ultrasonic sound of a turbulent gas leak. Using a technology called "heterodyning" it translates the sound to a lower frequency which your ear can interpret. AccuTrak maintains the original sound characteristics making it possible to distinguish leaks from other competing background sounds. AccuTrak is so sensitive you can actually hear the blink of an eye, yet most background noise will not interfere with detection accuracy.

Daqarta
Standard Windows sound cards do not respond to DC or frequencies lower than a few Hz. (See Why Sound Cards Block DC Signals below for explanation.)There are two general approaches to get true DC response from a standard sound card: Modify the card, or add an external circuit to convert the DC into an AC signal which can be easily measured by an unmodified card.

Daqarta
New Fcal option allows any Windows sound card to measure DC values like temperature or pressure using simple external circuits you can build yourself. Or, measure MHz frequencies with a simple prescaler. DAQARTA v5.10 turns your Windows sound card into a precision laboratory instrument, loaded with advanced features. Put your sound card to work!

SmartChamber - Metris B.V.
SmartChamber is the latest product in the Metris portfolio and provides the ideal environment for high quality Ultrasonic Vocalization measurements. In addition it is an answer to the growing requests for a measurement environment in which external stimuli and crosstalk between measurement cages is minimized. Current Sound Attenuation Chambers or Cubicles are designed to provide some sound isolation against normal laboratory sounds. For several reasons these chambers are not very suited for ultrasound vocalization experiments:

FX-910 - Qualectron Systems Corp.
Scan Time: 100 µs~500 s (depending on Computer Memory). Bandwidth: 10 Hz - 96 kHz (depending on Sound Card). Maximum Allowable Input Voltage (if connected directly): about 2 VAC (depending on Sound Card). Selectable sampling frequency (up to 192 kHz), sampling bit resolution (8, 16 or 24 bits) and sampling channels (one or two) (all depending on Sound Card)

Tamar Technology
With PULSE™ Technology, an ultrafast flash of laser light generates a sound wave that passes through an opaque film stack. When the sound wave encounters a film interface, an echo returns to the surface. The time between sound induction and echo detection provides a direct measurement of film thickness. With its ability to rapidly measure thickness, density, and other film parameters of multilayer stacks non-destructively and without interference from underlying layers or levels, PULSE is ideal for on-product process control measurements.

SPM9613 - Power Acoustics, Inc.
a low-cost computer program for analyzing community noise and sound propagation emitted from a variety of noise sources. The engineering software is based on the ISO 9613 parts 1 and 2 standards. SPM9613 provides calculations at specific field points (listeners) and predictions of A- and C-weighted sound level contours as well.
