Frequently Asked Questions
Is this test free?
Yes, completely free. No sign-ups, no downloads, no hidden fees. Just open the page and test your audio.
Is my audio data recorded?
No. All audio processing happens locally in your browser. Nothing is sent to our servers. Your privacy is protected.
Why can't I hear any sound?
Check that your speakers/headphones are connected and volume is turned up. Also ensure your browser isn't muted in system settings.
My microphone isn't detected?
Make sure you've granted microphone permission in your browser. Check that no other app is using your microphone exclusively.
What browsers are supported?
All modern browsers: Chrome, Firefox, Safari, Edge. For best results, use the latest version of your browser.
What is audio latency?
Latency is the delay between when audio is generated and when you hear it. Lower is better. Under 20ms is excellent for real-time audio work.
How accurate is the dB meter?
The dB meter provides approximate sound levels. For professional measurements, use a calibrated SPL meter. Our tool is great for relative comparisons and general room noise checks.
I can't hear high frequencies in the hearing test?
This is normal! Most adults lose high-frequency hearing over time. People over 25 often can't hear above 15-16kHz. Children can typically hear up to 20kHz.
