Sound Monitoring & Matching API based on Sound Similarity Measurement (for Sound Recognition Projects)
Sound recognition is one of the main application areas of artificial intelligence. Various sound recognition techniques exist and can be used for recognizing speeches, music, environmental sounds, animal sounds, air-borne or structure-borne machine sounds, etc. These techniques contain in common signal pre-processing, feature extraction and feature matching / classification algorithms from a general perspective. However, they differ in implementation in different applications. For example, there are a few good automatic speech recognition software products and APIs, however, they just cannot be used directly in animal sound classifications.

CAD Tool
Sabin
Sabin is a powerful CAD tool for room acoustics engineers. Based on statistical calculations, it determines the acoustical parameters of a user defined room, such as the reverberation time T60, the sound pressure level, and the RASTI as a measure of speech intelligibility. These parameters are updated dynamically, while the user is changing simulated sound sources and absorbing materials.

Sensitivity Testing
Response Dynamics Vibration Engineering, Inc.
Sensitivity testing involves making predictions of system response to environmental disturbance. The significance and importance of the system sensitivity estimates is very often overlooked. This gets companies in trouble and is one of the top reasons why we are called upon to provide timely solutions. Most teams are focused on getting their product to work and get it out the door. An engineering team will often not know how to quantify what to expect in the customer environment and how to test for those expected disturbances. We design hundreds of sensitivity tests and can explain the important concepts to consider in designing the tests and making the right measurements that allow for sound estimates of system response. This is an important expertise we use in our vibration, acoustic and magnetic field consulting services.

GeoSwath Module
The GeoSwath Plus Sonar Module contains a wide-swath bathymetric sonar suitable for a range of survey and inspection tasks. The GeoSwath Plus is a 500kHz interferometric sonar, or phase detecting bathymetric sonar (PDBS) from Kongsberg GeoAcoustics. Boat-mounted GeoSwath sonars are used worldwide for high accuracy surveys including port and harbour navigation and environmental mapping: the Gavia’s GeoSwath module makes this capability available in a commercial AUV. The GeoSwath Plus offers: wide swath coverage of up to 12 times the AUV altitude when near the seabed; integrated bathymetry with simultaneous true digital side scan; high depth resolution suitable for IHO survey standards; as well as the accuracy and repeatability of a boat-mount hydrographic survey system. Like most of the survey-grade sensors on the Gavia AUV, the GeoSwath data is time-synchronised with the AUV master clock using the vehicle PPS/ZDA system. Benefits of the GeoSwath AUV module include ease of deployment, ease of use, reducing survey time, and the ability to take a 500kHz high-resolution sonar down to targets in 1000m of water. The GeoSwath Plus post-processing software (provided as standard with the system) allows a user to inspect and process the data, create and inspect digital terrain models, and create basic sonar mosaics. Several other commercial post-processing software packages are also available, please ask for details. Note that for best results the GeoSwath Module should be deployed with a direct-reading sound velocity sensor (option) in the Control Module, and one of the high-accuracy INS/DVL Navigation Modules for motion sensing.

Bridge Decking Testing Equipment
The testing process can detect blow holes, inclusions or thin areas in 'sprayed-type' membranes. Because the concrete contains a small amount of water, it is electrically conductive and a DC Pinhole Detector can be used to create a high voltage which is passed over the surface by the use of a brush electrode. An alarm will sound to identify any small defects which can be rectified so that the integrity of the coating can be verified.

The Leading Measurement System for the Analysis of Porous Materials
ELWIS
ELWIS (Evaluation of Light Weight Impedance System) offers a full and rapid characterization of porous materials based on the analysis of a single sample. The ELWIS system consists of the ELWIS-A and ELWIS-S components which can be used independently from each other although both applications are needed for a complete material simulation.ELWIS-A measures acoustic parameters that are needed to evaluate the acoustic performance of sound insulation and sound-absorbing multi-layer materials. An additional impedance tube for absorption measurements at higher frequencies is available for ELWIS-A.ELWIS-S measures structural parameters that are needed to simulate the dynamic and acoustic behavior of sound packages in the medium to low frequency range (including the "Poisson Ratio" for foam materials).ELWIS is very easy to operate: Thanks to its user-friendly software, the system can also be used to obtain reliable results by users with only limited experience in the characterization of porous materials.
