SAFE - Structural Acoustics Foam Engineering This finite element program based program allows the analysis of sound traveling through various media including fluids, solids and foam-like substances for an overall approach to sound management. SAFE allows users to design optimal noise control treatments with such elastic porous materials as glass fiber, mineral wood and a variety of cell foams. The development of SAFE was partially funded by National Aeronautics & Space Administration (NASA).
ERAS - Echo Repeater Acoustics Source ERAS is a compact and versatile system for the performance evaluation of a wide range of active and passive sonar. It has been designed to be hand-deployed from small vessels with few facilities - the transducer assembly is a small lightweight unit containing both projector and hydrophone. At the surface, the system includes a rugged, portable, power amplifier unit and a controlling computer.
CAPE - Comet Acoustics Prototyping Engine CAPE is a graphical user interface application that guides and expedites the process of acoustic performance evaluation and optimization of noise control treatments in passenger vehicles. CAPE is used to predict sound pressure levels in the passenger compartment for various noise control treatment (NCT) configurations. The user can quickly and easily predict the effects of NCT changes such as changes to NCT material properties, thickness of NCT layers and order of NCT layers. CAPE allows the user to start with an existing template from a library that incorporates best practices and expertise. The user is then guided through the process of modifying the template model such that it represents a specific design candidate
ACOUSTIC TESTING Our acoustic testing experience includes acoustic qualification and evaluating sound pressure levels. We utilize microphones, pressure trans-ducers, and an acoustic intensity meter to record acoustic measurements.
Acoustic Noise A Test Specimens can be evaluated in two different modes in reference to acoustic noise: The Test Specimen's response to acoustic noise and the Test Specimen's generation of acoustic noise.

Unlike many others, the robust housing of the calibrator gives comfort of a secure grip to its users. Similarly to other SVANTEK acoustic calibrators, the SV 34 does not require adjusting as it compensates automatically the temperature and humidity changes.
OKO-75G - Acoustic Jammer Acoustic cell phone jammer OKO-75G is intended to block the acoustic channel of GSM phone when unexpected switching to transfer. The product does not respond to the signals of wireless phone standard DECT, providing extremely long battery life from a single battery with discharge monitoring. OKO-75G is powered by a lithium CR1220 battery.
Acoustic Enclosures Acoustic isolation requires carefully designed panel elements. One major factor for maximum isolation is a high weight-to-area ratio. Unfortunately, this generates large handling forces during opening and closing of the front door. IDE has integrated a servo-pneumatic mechanism to solve this problem.
SV 31A - Acoustic Calibrator The SV 30A type 1, two levels acoustic calibrator is the State of the Art instrument. The design of this calibrator is based on the dedicated ½" condenser microphone and microprocessor controlled signal source including digital static pressure and temperature compensation.

Differential Acoustic Emission Sensors Our differential sensors are identical to our general purpose sensors in physical, electrical and response characteristics, except that two signal leads (instead of one as for general purpose sensors) are brought out to attach to a differential pre-amplifier. By using a differential preamplifier, common mode noise is eliminated, resulting in a lower noise output from the preamplifier, and a higher electrical noise rejection in difficult and noisy environments. Noise improvements in the range of 2dB or higher can be expected using a differential sensor and preamplifier over a single ended general purpose sensor.
