Mitigation Strategies - RF and Ultrasoud

For most people the RF will be no more than an annoyance. Even when that's the case you may still want to mitigate it.  Here are a few ways to do that from simplest and cheapest to most involved:

Restricting surfaces used to limit sound being generated

• Tension clear packaging tape across any type of display - TV, laptop, desktop monitor
• This prevents the display from becoming a speaker due to effects from ultrasound or RF reflecting and transferring sound.
• Yes, ultrasound can actually do this.
• Digital Ventriloquism: Giving Voice to Everyday Objects on smashlab.io
• Stretch the tape as tightly as possible while applying it.
• Use an X pattern with 2 pieces of clear tape.
• Tension duct tape across walls
• This restricts any surface movement and prevents the surface from becoming a speaker due to effects from ultrasound or RF reflecting/transferring sound.
• Yes, RF can actually be used to do this.
• Have you ever heard voices that seemed to be from static or white noise?
• Stretch the tape as tightly as possible while applying it.
• Use the dull edge of a butter knife to rub the entire length of tape against the wall.
• This prevents it from relaxing and losing adhesion
• Start in the center of the wall and work in a spiral outwards (X's are numbered).

Both displays and walls can be used to create both audible sound and sound too low to be consciously heard (which makes it subliminal).

So don't dismiss it if no immediate difference is noticed.
