Noise levels for home DIY and workshop (comparison only)

A phone meter can help you compare which tool, corner or time of day is louder on your bench. This page is for comparison only. It is not hearing-safety, medical or workplace-compliance advice.

Fair comparisons

Use the same phone, weighting and distance from the tool every time. Mark your spot on the floor with tape. Reset statistics between runs. Note whether a compressor kicked in mid-test.

When the mic gives up

Impact drivers, saws and compressors up close often overload phone mics. If you see an overload warning or the level pins near the top of the scale, step back and compare at a farther fixed distance instead of trusting a clipped peak.

Workshop workflow

Compare tools, then compare locations (open door vs closed), then compare time of day if neighbors matter to you socially. Keep the weighting constant (Human Ear is a fine default for speechy comparisons).

What we will not say

We will not tell you how long you can work without protection, what legal limits are for your situation, or whether a reading means hearing damage. For those questions, use proper instruments and qualified guidance.

Example comparison plan

Pick two tools. Mark a spot two meters away. Use Human Ear weighting. Run ten seconds each, reset between, note max and average, and note any overload warning. Repeat once to see scatter. That spreadsheet is more honest than a single dramatic peak.

Neighbors and manners

Relative readings can help you choose quieter hours or a closed door. They still are not a legal noise survey. If a dispute needs formal evidence, that is a different process with different instruments.

Doors, distance and duty cycle

Closing a door, adding a rug, or moving a compressor outdoors can show up as a clear drop on a same-phone test. Duty cycle matters too: a tool that spikes once per minute looks different on max than on average. Capture both.

Again: none of these comparisons are hearing-safety prescriptions. They are DIY ranking tools for your own projects.

Putting it to work in DecibelDock

Open Sound level meter after you read this guide so the ideas attach to real controls. Use the same phone, the same weighting or instrument preset, and the same physical position whenever you compare two scenes. Prefer a blank reading, a held value, or a written rejection over a number that looks definitive but came from silence, clipping or chaos.

DecibelDock is built for exploration and relative checks on Android. It is not a calibrated or certified sound level meter, not a medical device, and not a substitute for professional instruments when safety, health or compliance are on the line. Direction, Doppler and Distance stay approximate and depend on your phone. The learn section exists to make those limits understandable — and to help the feature pages show up for the questions people already type into a search box.

When you are done experimenting, skim a related article below and the matching feature page. Internal links are intentional: each guide should send you somewhere useful next, not leave you on a dead-end paragraph.

If something in the app disagrees with this guide after a future update, trust the in-app How to use notes for that build, and treat marketing copy as secondary to what the screen actually shows.

Key takeaways

• Use the same phone and setup when you compare scenes.
• Prefer a blank or rejected result over a confident wrong number.
• Phone tools are for exploration and relative checks, not certification.
• Read the matching feature page for what the app actually shows on screen.
