Photos with a live decibel overlay — dB Pulse
dB Pulse can capture photos with a live decibel overlay as a free feature. A photo can preserve visual context alongside an approximate reading, but it does not prove a sound source, measurement duration or legal noise violation.

| Question | What to know |
|---|---|
| Free feature | Camera capture with live noise-level overlay. |
| Permissions | Camera access; photo-library access when saving requires it. |
| Useful context | Visible setup, source setting or placement. |
| Not established | Duration, source responsibility or certified accuracy. |
Capture context as well as a number
A sound-level photo can help you remember what you were comparing: the position of a fan, whether a window was open or where you placed the phone. Open Meter and choose the camera action. Allow camera access if prompted, and make sure the microphone is still unobstructed.
The camera view overlays the current meter information. Frame the relevant setup, then use the capture control. A visual record of placement can be useful, but the reading still reflects the phone’s microphone and settings at capture time. It is not automatically an average over the whole period you were looking through the camera.
Handle permissions deliberately
The feature needs camera permission to capture an image. Saving an overlay photo to the photo library may also require the relevant photo permission. If access is denied, the camera page provides an Open Settings route and a way to return without granting access.
You can keep using the meter without taking a photo. Granting camera access is not a requirement to turn every sound check into an image, and a missing permission should not lead you to misinterpret a stale overlay as a fresh capture.
Make the picture explanatory
Keep the microphone away from rubbing fingers or clothing while framing. If you move the phone close to the sound source to get a better picture, the measured level can change as well. Decide whether you need a measurement at your listening position or a close-up of the source; those are not interchangeable observations.
Add a separate note if duration, weighting or a calibration comparison matters. A still photograph cannot show how the sound varied before and after the shutter. For a timeline, save a session and use the photo as supporting context rather than the entire record.
Review before sharing
A useful picture can also reveal faces, addresses, screens or private possessions. Review the image and destination before sending it. Consider whether you can describe the setup without including people who did not expect to be photographed.
The photo overlay is free. Pro reports serve a different purpose when you want a structured session summary. Neither a photo nor a polished document turns an estimate into certified evidence or identifies who caused the sound. For official use, follow the appropriate local measurement and evidence requirements.
