SONASCREEN® -
SONOTEC GmbH
The handheld acoustic camera SONASCREEN generates acoustic images from both the audible and ultrasound frequency range. The device locates sound sources in real time and displays the results immediately on the screen. Furthermore, the camera provides audible feedback through industrial headphones. We make ultrasound audible and visible.

Acoustic Engineering
The Echo Speech Source Type 4720 is a small active loudspeaker box providing calibrated acoustic signals for speech intelligibility measurements using the Dirac room acoustics software. The Echo Speech Source is typically placed at a human speaker position. The received signal at the listener position is then picked up by a microphone and analyzed in Dirac to arrive at an accurate qualification of the speech intelligibility through parameters such as the Speech Transmission Index (STI). The Echo Speech Source operates from 4 AA batteries or an external mains power supply, and can be mounted on a standard tripod.

Jumho Electric Corporation
Noise source identification of large-scale machinery is a tough issue. If you don’t know the noise source, you cannot find out methods of improving you products. Microphone array, or acoustic camera, is an advanced technology for noise source identification in steady, non-steady, motion, or rest state. A microphone array system can display noise source distribution in real time, and identify the locations of noise source inside the equipment

BAS001 -
Larson Davis, Inc.
The BAS001 Source is designed to generate omnidirectional sound fields for making standard compliant measurements including: reverberation time (ISO 3382, ASTM E2235), building acoustics (insertion loss, acoustic absorption area, etc: ISO 140-4 ISO 140-3, ASTM E336, ASTM E90, DIN 55 210). The BAS001 is typically used to saturate a room with a uniform acoustic field. The available high-efficiency power amplifier has no fan for cooling, allowing measurements in quiet environments, like those in reverberation time applications.

AR700 -
Scope T&M Pvt, Ltd.
PD Defect Location in High-Voltage Equipment Insulation by Acoustic Sensors To act on deteriorating insulation the source of PD must be known.The insulation defects produce partial discharges, which emits electrical impulses, radiation of electromagnetic waves as well as acoustic signals.The AR700 measures acoustic signals with multiple sensors spread over the transformer. Then the software determines the failure location using the time difference of all incoming signals. Finally, these coordinates are shown in a 3D model of the transformer. AR700 device is used for measuring of acoustic signals on the external surfaces of gas-insulated breakers and substations, power transformers and other tank high-voltage equipment. The acoustic signals are caused by partial discharges in the insulation, which is the sigh of the defects.The advantage of “AR700” device is the quick installation of the acoustic PD sensors on the external surface of high-voltage equipment tank. The sensors have magnetic holder that is why there is no need to de-energize the equipment for the sensors installation. “AR700” device has 4 syn-chronic channels for acoustic signal measurement. This gives the possibility not only to find the defects in the insulation, but also to locate them. The location function of the “AR700”device is unique for acoustic devices.

BAS003 -
Larson Davis, Inc.
The BAS003 Source is designed to generate homogeneous sound fields using random noise in compliance with the following standards: Building acoustics (insertion loss, acoustic absorption area, etc: ISO 140-3, ASTM E90, ISO 140-5, ASTM E966). The BAS003 is typically used to generate a noise in a free-field for the evaluation of the transmission loss index of a façade. The available high-efficiency power amplifier, BAS002, is light and can be remotely controlled for easy use in the field.

Teledyne Marine Bolt
Bolt introduced the LONG-LIFETM air gun in 1992. Since then it has become the standard energy source for marine seismic exploration. It is a stable, trouble-free energy source that produces high acoustic output. Another signature advantage is the long work life between required maintenance.The Long-LifeTM product line offers three models with different output volume ranges.

HEAD acoustics GmbH
In order to optimize product sounds, it is necessary to know the exact point of origin of a sound source. This makes possible to identify the cause of disruptive sound components and rectify these effectively, optimize sound radiation and thereby achieve the desired sound experience. The ease of use and advanced beamforming algorithms of the HEAD VISOR acoustic camera allow sound sources to be located precisely at the blink of an eye.
