Decibel Meter Pro turns your phone into a practical sound level meter you can carry anywhere. The site positions it as a professionally accurate tool for everyday noise checks and more serious tasks, such as setting up audio systems, monitoring exposure, and documenting noise. Beyond basic dB readings, it incorporates a noise dosimeter, a quick hearing test that adheres to WHO criteria, spectrum analysis, and a clever feature that allows you to overlay live dB values on photos and videos. It aims to be the app you open when you need a reliable reading, a visual proof of noise, or a fast way to check if your listening habits are safe.
Pricing
The app offers many free features. There is also a Pro subscription tier that unlocks premium features. The company’s help article makes it clear that some users mistake the rich free feature set for an active subscription, and it explains how to manage or cancel a paid plan from inside the app or via device settings. Exact prices are handled by the app stores and may vary by platform and region.
How dB Pro works
Open the app and you are greeted by a large, readable decibel display with the current SPL value. From there you can switch modes based on what you are doing. If you want a quick exposure check, use the noise dosimeter to understand how long you can safely stay in a loud environment. If you are troubleshooting sound in a room or calibrating speakers, open the spectrum analyzer to see frequency content and adjust accordingly. If you want evidence of noise, use the photo or video overlay to capture an image or clip with the dB readings stamped on it and export that file. For a quick self-check of your hearing, run the integrated test and get a simple audiogram in a few minutes. The site emphasizes that the toolset is designed for both everyday users and audio-curious folks who want more control.
Features Decibel Meter Pro
1) Noise dosimeter for exposure awareness
The dosimeter view helps you detect dangerous noise without delay. This is useful at work sites, at home with loud tools, or in nightlife settings. The goal is simple. Know when levels are creeping into risky territory and adjust behavior before your ears pay the price.
2) Hearing test with a quick audiogram
A built-in hearing test gives you a snapshot of hearing health according to WHO criteria. In a few minutes, you can generate an at-a-glance audiogram that helps you spot issues early or simply track changes over time if you are listening loudly.
3) Photo and video overlays with export
Sometimes you need more than a number. With dB overlays on photos and videos, you can capture the moment and include the measured decibel value in the media itself. That makes it easier to communicate noise issues to a landlord, venue, event organizer, or coworker. You can export these files to share.
4) Noise Criterion and professional references
The app references professional standards such as the Noise Criterion that are used in places like hotels, schools, and cinemas. If you are assessing an indoor space, having those targets in the app helps you translate raw dB values into something actionable.
5) Spectrum analysis with depth
For audio work and room setup, the spectrum analyzer is where you can go deeper. The site highlights a powerful analyzer with many options that can support everything from tuning large halls to tweaking an audiophile setup at home. This is overkill for casual checks but great to have when you need it.
Security and privacy
The website links to a dedicated privacy policy and centralizes support on a contact page. That indicates a standard approach. For any subscription or data handling questions, you are directed to manage subscriptions through the app and refer to the published policy. If you prefer not to subscribe, you can still use the free features highlighted on the site.
