I grabbed my DeciSense just to settle an argument about how loud our AC unit really is. Turned out our normal living room sits around 45dB, and the cicadas outside our window hit over 90. Genuinely surprised me.

DeciSense™sound level meter
Precision And Proof For Every Noise Situation
Accuracy Apps Can't Fake
Phone mics aren't calibrated and can swing 5 to 10dB between devices. DeciSense holds ±1.5dB accuracy, so your reading is one you can actually trust.
One Meter For Every Volume
DeciSense reads the full 30-130dBA range, from a quiet nursery to a loud workshop, past OSHA's 85dBA safety limit and beyond.
Point It And Read The Number
One button turns it on, one glance gives you a number. There's no menu to dig through or setting to get right before your reading counts.
A Number You Can Point To
Hit hold the second the noise peaks and the reading freezes on screen. Max/min tracking shows the worst of a session, not just a guess.

Frequently Asked Questions
+164 expertsreviewed itNo handheld meter replaces a $2,000 pro rig for formal litigation, but an accurate reading is exactly what most landlords, HOAs, and mediators want to see before they act on a complaint.
Phone mics aren't built for this and can vary 5 to 10dB between devices, plus most apps stop logging the moment you switch apps. DeciSense is a dedicated, calibrated tool that gives you one steady number.
DeciSense holds ±1.5dB accuracy across its full 30-130dBA range, in line with the accuracy window most calibrated consumer meters are built to hit, just in a size that fits your pocket.
Yes. OSHA lists 85 dBA as the 8-hour exposure limit before hearing risk climbs, and DeciSense's 30-130dBA range covers everything from a quiet office to a running table saw.
Yes. Power it on, point it at the sound, and read the number. There's no setup, no settings to configure, and nothing technical standing between you and your first reading.
Pediatric guidance recommends keeping sound machines under 50 dB at crib distance. Place DeciSense near the crib to check your machine's actual level instead of guessing from the dial.
Yes. Hold the meter a few inches from the wall or ceiling where the sound is loudest and let the reading settle. Bass and low rumble usually read louder up close, so measure right at the source.
Yes, sound level drops the farther you are from the source, so readings taken right next to a speaker or wall will be higher than readings taken across the room. For consistent results, measure from the same spot each time.
