Disclaimer

Last updated: August 21, 2026

SoundDBMeter.com provides browser-based sound tools, calculators and educational content for general informational purposes. This Disclaimer explains the limitations that apply when you use the website or rely on its results.

SoundDBMeter.com is independently operated by Addito. Please also review our Terms of Service, which govern your use of the website.

Educational and Informational Purposes

The tools, articles, charts, calculations and other materials published on SoundDBMeter.com are intended to improve general understanding of sound, decibels, frequency, noise exposure and hearing awareness.

They are not intended to provide:

  • medical or audiological advice;
  • diagnosis or treatment;
  • legal advice;
  • occupational-health or safety certification;
  • workplace-compliance verification;
  • professional acoustic consulting;
  • certified environmental-noise measurements.

Information on the website should not replace advice, testing or measurements from an appropriately qualified professional.

Browser-Based Measurement Limitations

Microphone-based tools on SoundDBMeter.com use the microphone available through your browser and device. Consumer microphones differ in sensitivity, frequency response, maximum input level and signal processing.

Results may be affected by:

  • microphone hardware and placement;
  • device casing and microphone orientation;
  • automatic gain control;
  • noise suppression and echo cancellation;
  • operating-system processing;
  • browser implementation;
  • background noise and room reflections;
  • wind, movement or handling noise;
  • the quality of any user-applied calibration.

For these reasons, sound-level readings should be treated as estimates. They are not equivalent to readings from professionally calibrated Class 1 or Class 2 sound-level meters.

Frequency-analysis tools display relative information derived from detected audio frequencies. They do not automatically provide calibrated sound-pressure-level measurements.

See our Testing Methodology and Accuracy & Limitations pages for more information about how results are generated and what can affect them.

Calculation and Exposure Tools

Calculation tools apply the displayed mathematical formulas to the information entered by the user. Results depend on:

  • the accuracy of the entered values;
  • the selected units and settings;
  • rounding and software implementation;
  • the assumptions of the formula;
  • selection of the appropriate reference framework.

A correct calculation based on an inaccurate or estimated input will still produce a result that reflects the limitations of that input.

Noise-exposure calculators provide general reference information. They cannot determine whether an exposure is harmless for a particular person or whether a workplace complies with applicable law.

OSHA requirements and NIOSH recommendations have different purposes and legal status. Other countries and industries may apply different limits, measurement protocols or regulations. Always consult the rules that apply to your workplace and jurisdiction.

Online Hearing Test Disclaimer

The Online Hearing Test is a general screening and hearing-awareness tool. It is not a clinical audiogram and cannot diagnose hearing loss, tinnitus, an ear condition or another medical issue.

Results can be affected by:

  • headphone or speaker quality;
  • left and right channel differences;
  • device volume settings;
  • operating-system audio processing;
  • background noise;
  • the user’s listening environment;
  • how the test is performed.

A result that appears within an expected range does not prove that your hearing is medically normal. Similarly, a result that appears unusual does not confirm that hearing loss is present.

Online Hearing Test results may be saved in your browser’s local storage for convenience. They are not medical records, are not reviewed by a healthcare professional and are not stored as part of a clinical assessment.

If you have concerns about your hearing, consult a qualified audiologist, hearing-care professional or physician.

Sudden hearing loss, ear pain, persistent ringing, discharge, pressure, severe dizziness or another concerning symptom may require prompt professional attention. SoundDBMeter.com is not an emergency or medical-response service.

Tone Generator and Listening Safety

The Tone Generator and other audio-output tools can produce audible signals through headphones, speakers or connected audio equipment.

Actual listening level depends on the device, amplifier, speaker or headphones—not only on the settings displayed by the tool. A displayed frequency does not indicate a calibrated playback volume.

When using an audio-output tool:

  • begin at a low, comfortable volume;
  • increase volume only when necessary;
  • avoid prolonged playback;
  • do not test the limits of your hearing;
  • stop immediately if you experience discomfort, pain, pressure, dizziness or ringing;
  • supervise children where appropriate;
  • do not expose another person or animal to generated tones without appropriate awareness and consent.

You are responsible for controlling your device’s playback volume and using audio-output tools responsibly.

Hearing and Noise-Exposure Information

Articles discussing hearing risk, sound exposure and recommended limits are based on publicly available information from recognized institutions and other sources listed on our References & Sources page.

However, no exposure duration can be guaranteed to be safe for every person. Individual risk may vary depending on:

  • sound level and duration;
  • repeated or cumulative exposure;
  • frequency and impulse characteristics;
  • hearing protection;
  • age and hearing history;
  • existing health conditions;
  • individual susceptibility.

Terms such as “recommended exposure duration,” “permissible duration” or “exposure limit” describe a particular reference framework. They do not guarantee that harm cannot occur.

If you are uncertain about a noisy environment, reduce the exposure where practical and seek qualified advice.

No Medical or Professional Relationship

Nothing on SoundDBMeter.com creates a:

  • doctor–patient relationship;
  • audiologist–patient relationship;
  • attorney–client relationship;
  • acoustic-consultant relationship;
  • occupational-safety consulting relationship;
  • other professional-client relationship.

Using the website, receiving a tool result or contacting SoundDBMeter.com does not constitute a professional evaluation or individualized advice.

Workplace and Regulatory Use

SoundDBMeter.com’s browser-based tools are not designed, calibrated, tested or documented for certified occupational, environmental, legal or regulatory measurement.

Do not rely on them as the sole basis for:

  • OSHA or workplace-compliance documentation;
  • employee noise-exposure assessment;
  • hearing-conservation decisions;
  • environmental-noise reporting;
  • building or machinery certification;
  • insurance claims;
  • landlord or neighbour disputes;
  • government submissions;
  • court proceedings.

Workplace and regulatory measurements should be performed with suitable calibrated equipment, appropriate measurement procedures and qualified professional oversight.

Local requirements vary. Website content cannot determine whether a legal or regulatory violation has occurred.
