## Description

Every frequency your phone can actually produce, from a 20 Hz rumble to a 22 kHz tone almost nobody can hear.<br><br>High Frequency Sound is a precise tone generator and a hearing test in one. Set an exact frequency, watch it on the live trace, and read what that frequency really is: which band it sits in, its nearest musical note, its wavelength in air, and roughly who can still hear it.<br><br><br>TONE GENERATOR<br><br>• Full range from 20 Hz up to the highest tone your device can reproduce accurately, usually 22 kHz<br>• Sine, square, triangle and sawtooth, each built harmonic by harmonic so nothing folds back into buzz at the top end<br>• A logarithmic slider for sweeping, fine step buttons for nudging, or type the exact number you need<br>• A live scrolling trace that tightens and shifts tint as you climb the spectrum<br>• One tap to loop a tone for as long as you want it running<br><br>Presets worth hearing: the 17.4 kHz mosquito tone, the near ultrasonic band used by shop doorway alarms and pest deterrent devices, the 15,734 Hz whine of an old CRT television, a dog whistle pitch above human hearing, a common tinnitus ringing pitch, and concert A at 440 Hz.<br><br><br>HEARING TEST<br><br>A series of tones, each one higher than the last, starting at 8 kHz. Tap yes while you can still hear something, and no the moment it goes silent. Where you stop is your threshold.<br><br>• Your result in Hz, plus the age range that result is typical of<br>• A tone by tone breakdown of exactly what you heard and what you did not<br>• Replay any tone as many times as you like before answering<br>• Share your result if you want to compare with someone<br><br><br>YOUR RESULTS OVER TIME<br><br>Every test is saved with the volume it was taken at, because a threshold means nothing without one. See your best result, your latest, and whether your top end is holding steady. Delete anything you do not want to keep.<br><br><br>BUILT TO BE ACCURATE<br><br>• Audio is rendered at your device&#39;s own output rate, so a 19 kHz tone really is 19 kHz and not a resampled approximation of one<br>• Waveforms are band limited, which is why a square wave at 15 kHz stays a clean tone instead of turning into noise<br>• Tones fade in and out rather than clicking<br>• The app tells you honestly when your device cannot reach the top of the range<br>• Playback stops the moment a call or another app needs the speaker<br><br><br>PRIVATE AND OFFLINE<br><br>No account, no sign in, no internet connection and no permissions requested. Nothing you do here leaves your phone. Your results are stored on the device and are yours to delete.<br><br><br>ABOUT YOUR EARS AND YOUR GEAR<br><br>Phone speakers roll off badly at the very top of the range, so headphones give a truer reading. Set a comfortable volume before you start and leave it there for the whole test, because changing it partway makes the result meaningless.<br><br>High frequencies at high volume can damage hearing. Turn it down the moment anything feels uncomfortable, and keep sessions short.<br><br>The hearing test is a rough guide based on widely quoted age related thresholds, not clinical audiometry. It is a good way to find where your top end sits and to watch whether it moves over time. It is not a diagnosis and it cannot replace a proper hearing check. If you are worried about your hearing, see a professional.<br><br><br>WHO IT IS FOR<br><br>Musicians and engineers checking a room, a driver or a pair of headphones. Students working through acoustics. Anyone curious about where their own hearing gives out, or who wants to hear a mosquito tone properly. Anyone who has ever wondered what 18 kHz actually sounds like.<br><br>One app, the whole audible spectrum, and an honest answer about how much of it you can still hear.
