<h2 id="how-to-test">How to test your speakers</h2><ol><li>Turn the volume down to about a third. Test tones are louder than music, especially in headphones.</li><li>Press <strong>Test my speakers</strong>. You hear three short beeps from the left, then from the right, then from both sides, and the matching side lights up on the screen.</li><li>Answer <strong>What did you hear?</strong>. The page tells you whether your speakers work and, if they do not, what to check on your device.</li><li>For a closer look, use the tests under <strong>More tests</strong>: single sides, a frequency sweep, a tone generator, noise, a phase test and the speaker cleaner.</li></ol><p>The test works the same with laptop speakers, desktop speakers, soundbars, TVs connected to a computer, Bluetooth speakers, headphones and earbuds. It plays through whatever device your phone or computer is using right now.</p><h2 id="phone">Testing a phone speaker</h2><p>Open this page on the phone and press <strong>Test my speakers</strong>. Phones play web pages, videos and voice messages through the <strong>media</strong> volume, so raise it with the side buttons while the sound is playing.</p><ul><li><strong>Two speakers or one?</strong> Most recent iPhones and many Android phones use the earpiece at the top as a second speaker, so left and right come from opposite ends of the phone (hold it sideways). Phones with a single bottom speaker play both sides from the same place, and that is normal.</li><li><strong>Nothing on iPhone?</strong> Silent mode can mute sounds from web pages. Turn it off with the Ring/Silent switch or the Action button, then test again.</li><li><strong>Muffled or quiet?</strong> Remove the case and screen protector, and brush dust out of the speaker holes with a dry, soft brush.</li></ul><p>Step-by-step help: <a href="/fix-iphone-speaker-problems">iPhone speaker not working</a>, <a href="/fix-android-speaker-problems">Android phone speaker not working</a>, <a href="/fix-ipad-speaker-problems">iPad speakers not working</a>.</p><h2 id="stereo">Left and right channels</h2><p>Stereo music and films send different sound to the left and the right. If the sides are swapped, voices and instruments appear on the wrong side and games give wrong directions. Use <strong>Left</strong>, <strong>Right</strong> and <strong>Alternate</strong> to check each side on its own.</p><ul><li>One side silent: check the balance setting on your device and the cable or Bluetooth connection of that speaker. Mono audio, an accessibility setting, makes both sides play the same sound.</li><li>Sides swapped: swap the speaker cables, or check that your headphones are not on backwards. L and R are printed on most earbuds and headbands.</li></ul><h2 id="sweep">Frequency sweep and bass test</h2><p>The <strong>full range</strong> sweep glides from 20 Hz to 20 kHz in 14 seconds and shows the frequency it is playing. Listen for three things:</p><ul><li><strong>Rattles and buzzing</strong> at particular frequencies. They point to a loose part, a torn speaker cone or something vibrating near the speaker.</li><li><strong>Where the bass starts.</strong> Phone and laptop speakers usually stay silent below about 150–300 Hz; small desktop speakers start around 70–100 Hz; a subwoofer goes down to 30 Hz or lower. Use the <strong>bass</strong> sweep (20–250 Hz) to hear this more slowly.</li><li><strong>Where it ends.</strong> Most adults stop hearing the sweep somewhere between 14 and 17 kHz. This depends on your ears, not only on the speakers.</li></ul><p>The <strong>tone generator</strong> plays one frequency for as long as you want, which helps to find the exact frequency of a rattle. Pink noise sounds even across the whole range and is good for comparing two speakers or setting levels; brown noise has more bass.</p><h2 id="cleaner">Speaker cleaner: water and dust</h2><p>The speaker cleaner plays a low 165 Hz tone in short pulses for 30 seconds. The strong movement of the speaker can help push out water droplets after rain or a splash, and loosen dust. Hold the phone with the speaker facing down, use a medium volume and stop if the sound distorts.</p><p>It does not repair a damaged speaker, and it is not a reason to get a phone wet. Do not put a wet phone in rice or near a heater; let it dry in the air with the speaker facing down. If the sound is still muffled after a day, the speaker may need a repair.</p><h2 id="no-sound">No sound? Quick fixes</h2><ul><li><strong>Volume and mute.</strong> Check the system volume, the mute key, the speakers' own volume knob and whether this browser tab is muted.</li><li><strong>Wrong output.</strong> Computers often switch sound to a monitor (HDMI), a headset or a Bluetooth device. Choose your speakers in the sound settings.</li><li><strong>Bluetooth.</strong> Earbuds in their case, a smartwatch or a car can keep the sound. Turn Bluetooth off for a moment and test again.</li></ul><p>Full guides: <a href="/fix-windows-speaker-problems">no sound on Windows</a>, <a href="/fix-mac-speaker-problems">no sound on Mac</a>. If only one app is silent, see the guides for <a href="/fix-whatsapp-speaker-problems">WhatsApp</a>, <a href="/fix-zoom-speaker-problems">Zoom</a>, <a href="/fix-teams-speaker-problems">Microsoft Teams</a>, <a href="/fix-discord-speaker-problems">Discord</a> or <a href="/fix-google-meet-speaker-problems">Google Meet</a>.</p><h2 id="quality">Crackling, buzzing or distorted sound</h2><ul><li>Distortion only at high volume is normal for small speakers. Lower the volume in the app or system before blaming the speaker.</li><li>A steady low hum from desktop speakers, even with no sound playing, usually comes from the power or audio cable (a ground loop), not from the speakers. Try another power socket or a different cable.</li><li>Crackling with Bluetooth comes from the connection: move closer, and keep the phone out of your back pocket.</li><li>Sound effects and enhancements (equalizers, Dolby, spatial sound) can make speakers sound worse. Turn them off to compare.</li></ul><h2 id="phase">Phase test for home speakers</h2><p>Each speaker has a plus and a minus terminal. If one speaker of a pair is connected the wrong way round, the two speakers push against each other: the sound loses bass and seems to come from nowhere. Play <strong>In phase</strong> and <strong>Out of phase</strong>. In phase should sound fuller and centred between the speakers. If out of phase sounds fuller, swap the two wires on one speaker.</p><h2 id="privacy">Privacy and safety</h2><p>All sounds are created in your browser with the Web Audio API. Nothing is recorded or uploaded, and the page never asks for your microphone. Keep the volume moderate: loud test tones, especially high frequencies in headphones, can damage hearing and small speakers.</p><h2 id="faq">Frequently asked questions</h2><h3>Why do I hear only one side on my phone?</h3><p>Many phones have only one loudspeaker, so left and right play from the same place. If your phone has two speakers and one side is silent, check the balance and mono audio settings, then clean the silent speaker.</p><h3>Why does my laptop have almost no bass?</h3><p>Laptop speakers are too small to move enough air for low notes. The bass sweep shows where they start. For more bass, use headphones or external speakers.</p><h3>Can I test headphones and earbuds?</h3><p>Yes. Connect them first so the sound goes to them, then run the same tests. Start at a low volume.</p><h3>Can I choose which speaker to test?</h3><p>In Chrome and Edge on a computer, an <strong>Output</strong> menu appears when the browser can list your audio devices. Otherwise the page plays through the device selected in your system settings.</p>

<h2 id="how-to">How the online hearing test works</h2><p>There are two tests. The <strong>hearing age test</strong> plays higher and higher tones, from 8 kHz up to 20 kHz, and finds the highest frequency you can still hear. The <strong>left and right ear test</strong> plays short beeps in one ear at a time at six frequencies (250 Hz to 8 kHz), getting louder until you hear them, and draws a chart comparing your ears.</p><ol><li>Use headphones in a quiet room.</li><li>Play the reference tone and set a comfortable volume, then do not change it.</li><li>Start a test and answer as soon as you hear the sound.</li></ol><h2 id="age">Hearing age and the mosquito tone</h2><p>Children and teenagers often hear up to 19–20 kHz. With age, the highest frequencies go first: around 17 kHz in your twenties, 15–16 kHz at 40 and often below 12 kHz after 60. The famous <strong>mosquito tone</strong> (about 17.4 kHz) is a sound most adults can no longer hear. Loud music and noise speed this up.</p><ul><li>19 kHz or more: typical under 20</li><li>17.4 kHz: typical under 25</li><li>16 kHz: typical under 30</li><li>15 kHz: typical under 40</li><li>14 kHz: typical under 50</li><li>12 kHz: typical under 60</li></ul><h2 id="ears">Reading the left and right ear chart</h2><p>The chart is relative: 0 is the quietest level you heard during the test, and lower points mean a tone had to be played louder. Both lines should be close and fairly flat. A drop at 4 kHz is common after noise exposure. If one ear is 15 dB or more below the other at several frequencies, repeat the test and consider seeing a professional.</p><h2 id="limits">Limits of an online test</h2><p>Your headphones, your sound card and the volume setting affect the result, so this test cannot give calibrated values in dB HL like an audiologist’s audiogram. Many laptop speakers and Bluetooth earbuds cannot play tones above 16–18 kHz. Use the test as a quick check and a way to compare your ears, not as a diagnosis.</p><h2 id="faq">Questions and answers</h2><h3>Is this hearing test free?</h3><p>Yes, free, without an app or account. Nothing is recorded.</p><h3>Why can’t I hear the high tones at all?</h3><p>Check the volume and try other headphones: many devices cut frequencies above 16 kHz. Check that both channels work with our <a href="/">speaker test</a>.</p><h3>Can I do it on my phone?</h3><p>Yes, with headphones. Turn off sound effects or equalizers that change the sound.</p>
