How loud is a Theragun?
Nobody outside Therabody can say. The Theragun PRO, the Prime and the Mini carry no decibel figure on any product page or in any current manual PDF.
What Therabody offers is QuietForce Technology, a trademark, and sentences like "delivers quiet, deep muscle therapy". It does not publish a stall force or a percussions per minute figure either, and its 16mm amplitude appears only inside the manual PDF rather than on the page.
We are not saying a Theragun is loud. We have no idea, and neither does anyone quoting a number at you.
A site that ranks products by the figures makers publish cannot rank a product whose maker publishes none, so Theragun sits in the also considered list with the reason stated. Fellowes gets the same treatment in our paper shredder guide, and Whisker's Litter-Robot in our litter box guide.
Budget brands publish more specs than premium ones
In most categories we cover it runs the other way. Here it is consistent.
Renpho prints, in one block, noise, amplitude, stall force, speed range, battery life, weight, attachment count and warranty, and Opove gives the same set for the Apex and the M3 Mini. Both sell for a fraction of the premium guns. Hyperice, by contrast, gives a decibel figure and then no amplitude and no stall force for any Hypervolt in its range, with no warranty term on the product page. Ekrin Athletics gives a noise range and leaves out amplitude, stall force and weight.
To compare machines rather than brands, start at the cheap end. That is where the data is.
How many decibels is a massage gun?
Most makers answer with a ceiling, not a reading, and none of the eighteen products we checked names a measuring distance.
None names the speed setting either, none says which attachment was fitted, and none cites a test standard. The ceilings look like <=45dB, < 49dB and "below 40dB". A ceiling is a promise about the worst case, which is genuinely useful, but it is not a measurement you can line up against another brand's ceiling taken under conditions neither of them describes.
Hyperice's single 48 dB for the Hypervolt 3 is no easier to place, with no speed, attachment or distance behind it, and a massage gun figure without its speed setting cannot be matched against another brand's.
Ekrin Athletics comes closest to an exception. Its "35 - 55 dB Ultra Quiet" is a range across speeds, and while it still does not say which speed gives 35 and which gives 55, it at least admits the number moves.
Are quieter massage guns less powerful?
Here, yes. The lowest single figure and the lowest ceiling, "40dB" and "below 40dB", both belong to minis with less stall force than the full size guns.
| Gun | Noise figure | Stall force | Amplitude |
|---|
| Opove M3 Mini | 40 dB | 13.63 lbs | 7mm |
| Bob and Brad Q2 Ultra Max Mini | below 40 dB | 35 lbs | 5mm to 11mm, adjustable |
| Full size guns with 50 lbs of stall force | ceilings of 45 to 49 dB | 50 lbs | 10 to 14.5 mm |
That pattern is not a coincidence. A motor driving a longer stroke against more resistance makes more noise.
The useful way to read this page, then, is not to hunt for the smallest number. Decide how much stroke depth and stall force you need first. Then compare the published figures of the machines that clear that bar, single figures with single figures and ceilings with ceilings.
