Sound Level Calibrator
521
-
Accepted internationally 1 kHz represents the "0 dB" reference point of A, B, C Weighting and other filters utilized in acoustic measurement. The Pistonphone - a mechanical sound source - offers a slightly higher degree of accuracy at a substantial increase in cost. In addition, the 200 or 250 Hz operating frequency is mechanically limited and not suited for measurements of filtered inputs. The 0.2 dB accuracy is quickly lost in the 0.7 to 1.5 dB tolerances acceptable for weighting filters at frequencies around 250 Hz.

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.

Sound Source Localization
-
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.

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.
