About the Author: Addito

In short: Addito runs SoundDBMeter.com. They build and test the site’s sound tools and write and review its decibel guides. This page explains what Addito does on the site, how they research and test, and which pages they are responsible for.

Addito’s role at SoundDBMeter.com

Addito is the owner and author account of SoundDBMeter.com and runs the site independently. There is no separate editorial team: the person who designs a tool also writes its instructions, checks its numbers and answers correction requests, which keeps responsibility in one place. That covers everything from the homepage sound decibel meter to the smallest calculator.

  • Designing and building the browser tools
  • Writing and running the QA checks for each tool before release
  • Writing and reviewing the guides on decibels, noise exposure and measurement
  • Keeping accuracy and limitation statements realistic on every page
  • Handling corrections, bug reports and privacy requests

What Addito does not claim

Addito is not presented as an audiologist, doctor, acoustic engineer or occupational-health professional, and the site does not claim a degree, licence or certified status for its author. The work is meant to be judged on what you can check: the formulas, the sources cited and the published test results. Where a page touches hearing health or workplace law, it points to the official source and to qualified professionals rather than giving personal advice.

Topics Addito covers

The guides focus on questions readers actually ask about sound levels, from the basics to specific situations:

How Addito researches and tests

Research

Numbers start from primary sources: OSHA 29 CFR 1910.95 for the US legal limit, the NIOSH 1998 criteria document for the 85 dB(A) recommended limit, IEC 61672 for frequency and time weighting, EBU R128 and ITU-R BS.1770 for loudness, and WHO guidance on community noise and safe listening. Each is listed with a note on the references page. Everyday sound levels are given as ranges rather than single exact figures, because distance and room change them.

Testing

Each tool gets a written QA report before release. Tests run in a WordPress test install with Microsoft Edge and a simulated microphone that plays generated signals, so the expected answer is known in advance. For example, a 1 kHz test tone should read about 77 dB(A) on the meter; a 100 Hz tone should read 19.1 dB lower in dB(A) than in dB(Z), the IEC value (the test measured 19.0 dB); and the noise exposure calculator should return a NIOSH dose of 79.4% for 90 dB(A) over 2 hours. Every report lists the bugs found and fixed and the items that could not be tested, such as Safari on iPhone and real rooms. The method is on the testing methodology page.

Pages Addito built

Addito built every tool on the site and wrote the guides linked above. The tools include:

Each tool page explains how to use the tool, what the result means and where its limits are. The microphone tools also share one calibration setting: an offset saved once on the sound decibel meter is used by the background noise test, the classroom monitor and the volume level comparator on the same device, so their readings stay comparable.

How Addito keeps pages accurate

Pages that deal with readings carry a clear limit: a browser reading is an estimate, not a Class 1 or Class 2 measurement, as explained in how accurate an online decibel meter is. When a reader reports a problem, Addito checks it against the source or re-runs the test, corrects the page if needed and updates its date. AI tools may help with drafting and formatting, but facts, numbers and safety wording are checked before publishing. The full rules are in the editorial policy.
