Ogawa, H., Yamaguchi, S.: Evaluation of computing performance and measurement of power consumption on android devices. To play a sound of with a specific tone,we first have to create a sine wave sound.This is done in the following way. The results indicated that it is possible to execute an attack that intentionally increases the power consumption of Android devices and reduces the battery life. Reiwa 2nd year information and communication white paper (2020). As a result, we were able to reduce the usable time of the batteries of two Android devices to 3.1 h and 3.2 h, respectively. Use the Tone Generator below to listen to the 432Hz. Here at, we have provided you with the tools to make your own mind up. Skeptics will claim this is nothing more than pseudo-science. Ministry of Internal Affairs and Communications. Many people prefer the sound of 432Hz citing a calmer, more natural sound compared to its harsher relative, 440Hz.
