Block Porn On Cell Phone Is Safe For Humans

There are two types of recording shields ( Block Porn On Cell Phone ), one is ultrasonic interference (silent mode), and the other is white noise (acoustic noise mode) to prevent recording. Ultrasonic interference mode: Ultrasonic is a sound frequency emitted at a frequency that the human ear cannot perceive. It does not harm or affect the human body, but it will cause huge interference to all equipment that relies on the pickup to record sound. The frequency band it emits impacts the pickup film of the pickup head of the recording and video equipment, causing irregular frequency fluctuations on the pickup film, so that the sound recorded by these cell phone jammer devices is completely irregular noise. This is its rationale. Its advantage is that it is silent and safe for humans. White noise mode: White noise mode is the device emits irregular noise to mask the normal conversation sound.

Conversation in white noise mode should be conducted in a low voice as much as possible, at a volume just enough for both parties to hear clearly. White noise mode is a tone interference mode, so it is only suitable for use in open, informed situations. Block Porn On Cell Phone By emitting ultrasonic waves with random noises that cannot be perceived by human ears, when digital devices such as mobile phones are recording, these noises and normal conversation sounds are recorded into the digital device, making the recorded audio invalid. The mobile phone jammer also has the same interference effect on the audio information in the captured video. Since the ultrasonic noise is randomly generated and cannot be restored, the disturbed audio cannot be restored, thus ensuring that the original information will not be leaked. and spread. The sound produced when working is comparable to the sound of a computer fan.
