Important information about the limits of Sound Tester's tools, results and content. Please read it before relying on any test, reading or guide.
Sound Tester offers free browser tools and guides for general information and everyday testing only.
All tools, guides, reviews and other content on soundtester.net (the "Site") are provided in good faith for general information, education and everyday audio testing. While we work to keep everything accurate and up to date, as described in our Editorial Policy, we make no guarantee about the completeness, accuracy or reliability of any information or result.
Any action you take based on the Site is strictly at your own risk.
The Hearing Test, hearing range checks, ear age estimates and all hearing and noise content on the Site are not medical advice and are not a substitute for a hearing test by a licensed audiologist or a diagnosis by a doctor.
Tones, sweeps and noise are generated digitally and are exact in frequency. How they sound, and any reading taken through a microphone, depends on hardware and settings we cannot control.
| Tool | What affects the result |
|---|---|
| Decibel Meter | Microphone quality, auto gain and noise suppression, phone case, calibration. Readings are estimates, not Class 1 or Class 2 sound level meter results. |
| Mic Test score | Room noise, distance from the mic, browser audio processing and system input level. |
| Spectrum Analyzer | Microphone frequency response, FFT settings and the sample rate of your device. |
| Bass and range tests | Speaker and headphone limits, room acoustics, Bluetooth compression and audio enhancements. |
Results are best used for quick checks and before-and-after comparisons on the same device.
Test sounds can be loud, and high or very low frequencies can be harmful even when they are hard to hear. You are fully responsible for the volume you use and for the equipment you play sound through.
