SoundGraphy

Making sound visualization simple

SoundGraphy

SoundGraphy is an easy-to-use handheld device that visualizes sound. Using wireless connectivity, SoundGraphy offers easy sound source identification and visualization expanding the functionality of a sound level meter, but operation is kept similar.
Sound visualization systems require numerous microphones and a complicated measurement system combined with cameras, making them expensive. SoundGraphy includes only the necessary features, thereby greatly reducing cost. With this product, Nihon Onkyo Engineering aims to make sound source identification affordable, easy, and accessible.

Applications of SoundGraphy

SoundGraphy fulfills the needs for sound source identification and visualization in situations where the measurement time is limited, and where costs are a concern.

Quality inspection

Quality inspection

When acoustic measurement is required for inspecting quality, the major metric is sound pressure level. With SoundGraphy, users are able to identify where the noise is come from, in addition to the sound pressure level. Moreover, in the event a product is returned as a defective product based on noise complaints after sale, SoundGraphy can help to identify the cause of the problem.

Equipment diagnosis

Equipment diagnosis

Machine tools and test equipment include components that must be replaced on a regular basis. In some cases, the equipment generates abnormal sounds as the parts begin to wear out. SoundGraphy allows users to address such sounds as signs of malfunction. Soundgraphy can identify the source of such noise and contributes to appropriate management and stable operation of the equipment.

Visualization of effects

Visualization of effects

Let's take a look noise control parts as an example. When selling such parts, can customer image its effect as they read the explanatory sentence or words on a brochure for evaluating the noise reduction effectiveness?
SoundGraphy allows users to visualize the effectiveness of a product, enabling more advanced promotion of the product's abilities. With operation taking about a minute only to start up, SoundGraphy is also an attractive measurement option in situations where the amount of time for measurements is limited.

System configuration

SoundGraphyThe SoundGraphy system comprises three components; the sensor, the processor unit, and a tablet PC. With Wi-Fi (wireless LAN) connectivity between the processor unit and the tablet PC, connections are cable-free. This makes the system highly portable and usable in a variety of situations.
