NOTICE: Please note that listening to ultrasonic audio at unreasonable levels may cause physical damage to your ear, which can affect or damage your hearing. By downloading or listening to these programs, you accept full responsibility for the results of using these programs in any unreasonable or inappropriate manner, including (but not limited to) listening to ultrasonic audio on headphones, earbuds or any other headset, or by listening to ultrasonic audio loudly over speakers. If you experience tinnitus, ear pain, or any other unwanted sensations, stop usage of the ultrasonic audio program immediately. As you’ll see in the instruction manual, use a frequency analyzer app (we recommend Frequensee) to check the level of the ultrasonic audio, and never listen over -20db.
