Frequently Asked Questions
Common questions about Ultrasonic Frequency Emitter (15kHz - 22kHz), audio processing, and usage.
Most adults over 25 cannot hear frequencies above 15 kHz to 17 kHz, while children, teenagers, dogs, and cats can hear up to 20-22 kHz and beyond.
Standard computer speakers and studio tweeters can reproduce up to 20 kHz (the Nyquist limit of 44.1 kHz audio is 22.05 kHz). However, laptop speakers may roll off sharply above 14 kHz.
Dogs can hear sounds up to 45,000 Hz. A frequency of 18,000 Hz to 22,000 Hz is often perceived clearly by canines while remaining silent to human adults.
