About
Who we are and why we built this tool.
Online Decibel Meter helps you make sense of sound levels with simple explanations, practical guides, and a free calculator. Our goal is to help classrooms, hobbyists, and small shops measure reliably and protect hearing.

Our Mission
Make sound measurement understandable and accessible for everyone—students, creators, hobbyists, and small teams—so decisions about comfort and hearing safety are based on good numbers, not guesswork.
Who We Are
We’re a small, independent team focused on practical tools and plain‑language guides. We value accuracy, clarity, and respect for users’ privacy. Questions or ideas? Email everydayroyalties@gmail.com.
How the Meter Works
- Weighting: You can interpret results using A‑weighting (general environmental noise) or C‑weighting (more low‑frequency content).
- Logarithmic math: dB values are ratios; combining sources uses power addition, not simple sums.
- Distance: Levels drop ≈6 dB per distance doubling in free field; rooms can differ due to reflections.
See the Guide for step‑by‑step examples and the math we use.
Accuracy & Limitations
Phone microphones vary and may clip at high levels; for safety or compliance, use a calibrated sound level meter. Our calculator is for education and planning, not regulatory certification.
Responsible Use
- Protect hearing when levels exceed safe exposure for the task.
- Be mindful when measuring people or in private spaces; always follow local laws.
- Use measurements to inform choices—distance, duration, and protection matter.
Attribution & Thanks
We’re grateful to the acoustics and hearing‑health communities for decades of research that make practical tools possible. Terminology and rules of thumb (A/C weighting, LAeq, 3 dB exchange) are standard in acoustics literature.

Our Approach to Sound Tools
We want meters that feel approachable enough for everyday life while still respecting the science behind them.
Many sound tools are split into two extremes: playful apps with little explanation, or technical software written only for specialists. Online Decibel Meter aims to sit in the middle. The interface stays simple enough for a quick check, while the guide, FAQ, and blog dive into concepts like weighting, exposure limits, and distance loss.
We design content so that curious listeners, creators, and small teams can build a mental model of how sound behaves. When you understand those patterns, the numbers on the screen stop being mysterious and start becoming useful.
Who Online Decibel Meter Is Designed For
This site is built for people who want clarity without learning an entirely new profession. That includes curious listeners, parents and caregivers, musicians, creators, remote workers, and anyone who suspects that sound plays a bigger role in their comfort than they realized.
You do not need to know calculus or own expensive equipment to benefit. If you can notice patterns and make small adjustments, you can use the meter and guides to gradually shape quieter, healthier routines.
How We Hope People Will Use This Site Over Time
Our long-term goal is that tools like this become as normal as checking the weather. You might glance at the meter before turning music up for a gathering, take a quick reading when a new appliance sounds off, or skim an article when your workday feels unusually draining.
By revisiting the site at key moments—before buying gear, rearranging a room, or starting a new routine—you can let a basic understanding of sound guide your choices instead of guessing based only on how something feels in the moment.
Learning From People Who Use the Tool
We pay close attention to the situations people describe when they write to us or share feedback: small apartments, busy rehearsal spaces, shared offices, and more. Those real stories influence which examples we highlight and which explanations we refine, so the site stays grounded in everyday experience instead of abstract theory.
