Description:
NOTICE: In some phones the application may not work, depending on the speakers that your mobile phone has.
NOTICE: the application was tested on an LG Phone and on an ASUS Tablet.
YABLO is an air blower application to show kids how sound works. In particular the application produces a sound wave with a frequency that can be selected by the user. At a given frequency, depending on the mobile phone, the soundwave can blow air to turn off a near candlelight or move little pieces of paper. In order to help the user in finding the right frequency, the application also provides a small explanation about the frequencies to be used to observe the desired effect on the candlelight.
The application does not store any sort of data. It requires network permissions to show advertisements.
The application allows to set the frequency (between 0 and 2000Hz) of the soundwave and its amplitude (between -16Db and 0Db).
In order to work, the user has to keep the activate button pressed.
See the video or contact us for further information about the application.
