4ch Beam Forming Sound Source Visualization System
BF-3200/MI-5420A/BF-0310
Beam Forming is one of the sound visualization techniques that obtains the sound pressure distribution using the phase differece information from the sound source to the microphone, and makes it visualized with the color map.This technique requires a lot of microphones to cover a wide area and generally tends to increase the size of the system. By this Beam Forming system, Ono sokki achieved real time sound source visualization with just 4 microphones.

Noise Dose Meters
Here you will find a full range with an industrial standard noise dose meter to suit every requirement. With the portable noise dose meter you can carry out measurements quickly to gain control of a situation or to set the device to take timed measurements. The noise dose meter is important for all industries, especially by using it as a mobile device which is able to assess office stress levels or street noise levels.Often problems arise from noisy neighbors or if bars and restaurants are in residential areas and produce noise levels after 10pm in excess of what local laws permit. We, of course, can assess which noise dose meter you require in relation to the issue you have and the relating laws. We also have microphone extension cords, tripods, calibrators and calibration certificates for most models of noise dose meter.

Microphone Arrays
One of the most important parts of an Acoustic Camera is the microphone array. It determines the spatial distribution of the acoustic microphones and therefore measurement performance of the whole system. In order to achieve the maximum possible performance in any given application, we offer a wide variety of microphone arrays. No matter if the measurement is beamforming, intensity or holography ... we have the right microphone array. For special applications we can design and build custom made microphone arrays according to the requirements of the application.

MIPI SLIMbus
A typical mobile device has many low-speed/bandwidth peripherals connected to the host processor, which include microphones, speakers, sensors and many others. There is a need for a standard bus that enables multiple audio channels, peer-peer communications and lower pin count on the host processor. The MIPI alliance has defined the SLIMbus specification which provides a standard, robust, scalable, low-power, high-speed, cost-effective, two wire multipurpose interface that supports a wide range of digital audio and control solutions for mobile terminals.

Directional Microphone
MI-8100
MI-8100 is a shotgun type directional microphone which sharply catches the intended sound. This directional microphone is helpful for the removal of background noise in the simple sound source exploration and in abnormal sound detection. Flat frequency characteristic from 50 Hz to 20 kHz and sharp detection with high S/N ratio provide high sensitive detection of various sound coming from the specific direction. By combining the acoustic vibration monitor BL-1100, only the intended frequency or sound is focused and caught clearer.

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.

SparkFun TRRS 3.5mm Jack Breakout
TRRS connectors are the audio-style connectors that you see on some phones, MP3 players and development boards. TRRS stands for "Tip, Ring, Ring, Sleeve," which reflects the fact that, unlike a standard stereo connector, this actually has three conductors and a ground. Some devices use the extra conductor for a microphone (like hands-free headsets) or to carry a video signal (like in some MP3/MP4 players). This breakout board makes it easy to add a TRRS jack to your prototype or project by breaking out each conductor to a standard 0.1" spaced header.
