INFOSOUND is a technology for transmitting and receiving information by converting digital data into sound which is inaudible to most people.


Easy control of transmission range

INFOSOUND relies on sound and thus allows fine control over the area it is transmitted to, unlike GPS or WiFi. For example, you can limit the communication range by reducing the volume level or setting up walls as sound barriers. In these ways, you can deliver information within a specific area when you need it.

Simultaneous transmission to multiple recipients

Whereas QR codes and NFC (Near Field Communication) technology work on a one-to-one basis, INFOSOUND can simultaneously transmit information to multiple recipients within the range of sound. This allows visitors to receive information easily in crowded stores or event venues.

Unobtrusive sound

INFOSOUND uses a frequency band that is almost inaudible to the human ear, so it will not affect existing sound sources. INFOSOUND can be played with other sound, or almost silently by itself. Thus, the sounds generated by INFOSOUND will not interfere with you and your guests.

A safe sound

INFOSOUND is more noise resistant than other acoustic communication technologies. It allows information to be conveyed using low volume levels, so that the technology can be utilized safely with little burden placed on the human ear. Joint research with a medical university confirmed that there is no observable increase in stress due to INFOSOUND audio signals at volume levels normally used in communication.

With these features, INFOSOUND can be used to transmit information to a wide area through TV broadcasts and over the Internet, or just in front of a shelf in a store. To see how INFOSOUND can be used, please refer to the examples of its application below. In addition to the applications mentioned here, we can suggest applications that use INFOSOUND to suit customers' needs.
