## What is Audio frequency generator?

A single frequency
• generate tones (ultrasonic) with frequencies between 10Hz and 25000Hz.
• test your hearing: on average, humans hear between 20Hz and 20,000 hz, but hearing deteriorates with age, especially at frequencies close to ultrasound. Some people use this fact to harass teachers in the classroom by producing ultrasonic waves that only young people can hear.
• the sound generator can simulate a dog whistle and help you train your dog by generating a very high frequency.
• you can try it as a repellent, but be aware that some scientific studies have found that ultrasound is not an effective solution for repellent mosquitoes. Anti-mosquito apps usually drive away mosquitoes by producing frequencies close to ultrasonic waves (15,000 Hz to 22,000 Hz). Also suitable for rat and mosquito repellent applications.
• find out your tinnitus frequency. Whenever needed, it produces tones that mask tinnitus.

Bass test
• learn how your audio device handles very low frequencies. Best for subwoofers and headphones.

Remove the water
• remove water from the phone's speaker. If your phone falls into the water, the speaker sound may now disappear. The vibration caused by the generated frequency will help remove the water and repair the speaker.

For more tips
• keep in mind that the generated tones can be very annoying and stimulating to those around you. Always use this application responsibly. Also, keep the volume low to avoid damaging your hearing. If you raise the volume to better hear very low frequencies, don't forget to lower the volume later: the perceived volume of a tone depends on its frequency.
• when producing ultrasonic tones (20000 Hz and higher), the speaker may produce additional parasitic sounds. Just because you hear these sounds doesn't mean you can hear the actual frequency being played.
