About the Author – Addito

Founder, Writer and Tool Researcher at SoundDBMeter.com

My name is Addito, and I am the founder and independent writer behind SoundDBMeter.com. I research sound-measurement concepts, develop and test browser-based audio tools, and create educational content about decibels, sound pressure, noise exposure and hearing awareness.

I created SoundDBMeter.com to make sound-related information easier to understand without hiding the limitations of consumer devices. A sound-level result is only useful when users know what it represents, which factors may affect it and when a professional instrument or qualified specialist is necessary.

Why I Created SoundDBMeter.com

Many online sound tools display a number without explaining how it was produced or how much confidence users should place in it. At the other end of the spectrum, professional acoustic standards and occupational-noise documents can be difficult for general readers to interpret.

SoundDBMeter.com aims to bridge that gap.

The website combines accessible browser tools with plain-language explanations of the underlying concepts. My goal is not to present a phone or computer as a professional measuring instrument. It is to help users observe sound, understand common terminology and make better-informed decisions about when further measurement or professional guidance may be appropriate.

You can read more about the website’s purpose on the About SoundDBMeter.com page.

What I Work On

My work for SoundDBMeter.com covers four connected areas.

Browser-based sound tools: I work on tools that use browser audio technology or documented mathematical formulas. This includes the Online Decibel Meter, sound calculators, microphone utilities and frequency-analysis tools available in the Sound Tools directory.

Tool testing and documentation: I examine how device microphones, browsers, calibration settings, room conditions and signal processing can affect results. I document relevant limitations so users can distinguish a convenient estimate from a certified measurement. The site’s Testing Methodology explains this process in greater detail.

Decibel and acoustic concepts: I research topics such as sound pressure level, the logarithmic decibel scale, frequency weighting, sound intensity and the differences among commonly used decibel units. My aim is to explain these subjects accurately without making them unnecessarily difficult to follow.

Noise-exposure and hearing-awareness information: I review publicly available guidance about occupational and everyday noise exposure. Because organizations such as NIOSH and OSHA have different roles and use different exposure frameworks, I try to preserve those distinctions rather than combine them into one universal rule.

How I Research and Review Content

For safety-related and regulatory subjects, I prioritize original publications from government agencies, standards organizations, research institutions and other authoritative sources. Secondary sources may help provide context, but important figures and claims should be checked against the most relevant primary material available.

Before publishing or materially updating a page, I consider:

  • whether the claims are supported by appropriate sources;
  • whether recommendations and legal requirements are clearly distinguished;
  • whether uncertainty or conflicting guidance needs to be disclosed;
  • whether the tool or calculation behaves as described;
  • whether users are told about limitations that could affect interpretation;
  • whether the content is understandable without losing technical accuracy.

The complete content-development, review and correction process is described in the Editorial Policy. Frequently used institutional and technical materials are listed on the References page.

Accuracy and Transparency

Browser-based measurements can be helpful for observing patterns and making general comparisons, but consumer microphones are not standardized acoustic instruments. Results may change with the device, browser, microphone processing, distance, position and surrounding environment.

Calibration may improve agreement with a trusted reference under similar conditions, but it does not convert a consumer device into a certified Class 1 or Class 2 sound-level meter. I try to make this distinction visible wherever it materially affects the use of a tool or interpretation of a result.

The Accuracy and Limitations page explains what the website’s tools can reasonably support and where calibrated equipment should be used instead.

Selected Work

Examples of the tools and resources I maintain include:

These pages represent different parts of my work: tool research, calculation logic, technical documentation and source-based educational writing.

Professional Scope

I do not present myself as an audiologist, physician, certified acoustician, occupational hygienist or legal or regulatory adviser. SoundDBMeter.com provides educational information and general-purpose tools, not medical diagnoses, workplace certifications or legal measurements.

When a decision depends on certified accuracy, hearing health, regulatory compliance or immediate safety, users should consult an appropriately qualified professional and use suitable calibrated equipment.

Contact Me

I welcome questions, constructive feedback and reports of possible errors. If you identify an outdated source, incorrect figure, unclear explanation or unexpected tool result, please include the relevant page and enough detail for me to investigate.

You can:

Credible correction requests are reviewed, and content is updated when a change is supported by the available evidence.
