Disclaimer

Last updated: June 2026

The information, tools, and resources provided on SoundDBMeter.com are intended for general informational and educational purposes only. The website is operated by Addito (contact available via the Contact page).

By accessing or using this website — including the Online Decibel Meter and related tools — you acknowledge and agree to the terms outlined in this Disclaimer.

1. Educational and Informational Use Only

SoundDBMeter.com provides browser-based sound measurement tools and educational content about decibels, sound pressure levels, and noise safety.

All content on this website — including articles, charts, comparisons, and exposure guides — is provided for informational purposes only and should not be interpreted as:

Medical advice
Legal advice
Occupational safety certification
Regulatory compliance verification
Professional acoustic consulting

If you require professional evaluation, certified measurements, workplace compliance validation, or medical assessment related to hearing health, consult a qualified professional.

Research and editorial standards are outlined in the Editorial Policy.

2. Not a Certified Sound Level Meter

The microphone-based measurement tools on SoundDBMeter.com — including the Online Decibel Meter, Background Noise Test, and Frequency Analyzer — are browser-based estimation tools.

They are not certified Class 1 or Class 2 sound level meters and are not approved for:

OSHA compliance documentation
Workplace safety certification
Legal proceedings
Government reporting
Environmental compliance verification

For regulatory, legal, or occupational purposes, professionally calibrated and certified equipment must be used.

3. Pure Calculation Tools: Mathematical Accuracy

The SPL Converter, Volume Level Comparator, and Noise Exposure Calculator are mathematical calculation tools, not measurement estimation tools.

These tools do not use a microphone. They perform calculations on numeric values you enter, using established acoustic formulas. The mathematical output is exact within the precision of the input value provided and the formula applied.

However, the regulatory usefulness of these results still depends on the accuracy of your input values. If you enter an estimated dB level from a non-certified source, the calculated exposure time will reflect the limitations of that estimate — not a deficiency in the calculation itself.

4. Accuracy and Device Limitations

Sound level readings generated through the microphone-based tools depend on multiple variables beyond our control, including:

Microphone sensitivity and hardware quality
Device manufacturer differences and microphone frequency response
Operating system audio processing, automatic gain control, and noise suppression
Browser audio handling and Web Audio API implementation differences
Environmental acoustics and background noise conditions
Calibration accuracy

Because of these factors, readings from the microphone-based tools should be considered approximate estimates only — not calibrated sound pressure level measurements. For a full explanation of technical constraints, see Online Decibel Meter Accuracy and Testing Methodology.

5. Hearing Safety and Exposure Information

Pages discussing safe exposure limits, hearing damage risk, and regulatory guidance — including the Safe Noise Levels Chart and Hearing Damage dB Chart — are based on publicly available guidance from recognised institutions including NIOSH, OSHA, and WHO.

However:

Individual susceptibility to noise-induced hearing damage varies significantly
Local regulations may differ by jurisdiction and may have been updated
Workplace noise standards may be revised over time by regulatory bodies
The tools on this site do not account for personal hearing health history or pre-existing conditions

You should not rely solely on this website when making medical, workplace compliance, or regulatory decisions. If you have concerns about hearing health, consult a licensed medical professional or audiologist. If you require workplace compliance guidance, consult a certified occupational health and safety specialist.

6. No Medical or Legal Advice

Nothing on SoundDBMeter.com constitutes medical, legal, or professional advice of any kind. The use of this website does not establish any professional-client relationship. Users are solely responsible for how they interpret and apply the information provided.

7. Regulatory Independence

References to NIOSH, OSHA, WHO, CDC, and other institutions throughout this website are for informational and educational purposes only. SoundDBMeter.com is not affiliated with, endorsed by, or approved by any of these organisations. A list of sources used in educational content is on the References page.

8. Limitation of Liability

To the fullest extent permitted by applicable law, Addito and SoundDBMeter.com are not liable for:

Hearing damage arising from reliance on tool readings or educational content
Workplace safety violations or regulatory penalties
Decisions made based on tool results or published information
Technical failures, downtime, or performance issues
Any direct, indirect, incidental, or consequential damages arising from use of this website

All use of this website is entirely at your own risk.

9. Updates to This Disclaimer

This Disclaimer may be updated periodically. The effective date at the top of this page will be updated when material changes are made. Continued use of the website after an update constitutes acceptance of the revised terms.
