Questions about Euphony's range of sound waves

[HongEunbeen]

Hi🙌

I'm thinking about the idea of ​​a sample app using a Euphony's library, and I'm curious how the range of sound waves is determined.

How far can the receiver receive the sender's data?
Can a developer or user set range of sound waves throgth a library?

Is it possible to measure the distance by the timestamp of sending and receiving? 🙏

• When I personally tested it, it was smooth up to about 1-2m
• The proper distance has changed depending on the volume of the device
• If the volume is low, you have to place the devices close to each other

Thank you for answer. I think it would be nice to have a document about sound waves distance..!!🤔

I think this answer is the most appropriate! :)

Euphony uses high notes in sound waves, it has a straight-forward characteristic.
Therefore, the recognition range varies depending on the direction of the speaker.

As @zion mentioned, ~2m is typical, and if you take advantage of the straight-line characteristic, you can send it up to 5m.

As you know, since it's a sound wave, you can adjust the transmission range by adjusting the volume.

I remember that the maximum distance is about 5m at the launching ceremony. However, as @zion830 answered, it seems to be slightly different depending on the setting of the devices and the environment of the test space.

@Kimhaedam @zion830 How could you know about the maximum distance..?

When the remaining people went to the study center after the launching ceremony, briefly ran the Euphony, and I heard it then.😀
