Decibel scale is logarithmic. 10dB on top of 100dB isn't 10% louder...it's waay more (theoretically). But the comparison between the two models of buzzer isn't really showing that much difference as you say
10 dB difference means that audio is heard twice louder or half quieter. 3 dB is usually the difference that can be noticed compared to other (ie. 13 dB vs 10 dB). So 1-2 dB difference is not really noticed, but 5-6 dB difference becomes easy and 10 dB is obvious difference. But when you have something as a 100 dB, it is well past the office/street noise of 60 dB. Slamming a door is about 80 dB and 120-130 dB is a common chainsaw or other high power tool. And 30 dB is a background noise inside a room on silent street. If something goes under 30 dB, it is already like being in forest middle of rural area. Closest to 110 dB is a common car horn just next to car. So very very loud to not find something anywhere close by. Here where I live a DJI Mavic Mini can be heard easily from 70 meters altitude and about 200 meters away (slant range is ~210 meters) when there is no wind, because the landscape is such that you can hear even a normal speech volume (60 db) from 600-800 meters away at the winter time when there is snow cover. In the summer it drops to about 400-500 meters when it is dry, and after the rain it becomes about 100-200 meters. But because a drone flies higher altitude, its volume doesn't get traveled above terrain so easily. I have made some tests and at about 300-400 meters the drone noise starts to vanish to the background if you are not carefully listening knowingly that you are trying to hear it. This is because the drone pitch is higher at about 80-82 dB volume. Now, consider that you have a 100 dB or 110 dB buzzer activating... There is no way that you can't hear that thing in such distances if you have LOS to it. If in deep in the forest, the sound waves gets scattered and muffled and you might hear it only from shorter distance (but I doubt). Few years ago I was recording swans singing with normal stereo microphone (Zoom H2n) with great results from 1.8 km distance at winter time, where 1 km was over the frozen, snow covered lake. You could even very clearly hear a normal street motorcycle (~100 dB!) moving over 4 km away through a forest road. I could track the bike by its sound alone, as it was moving on the road that I am very familiar and know the curves and hills, it was funny that what you can do just with noise alone. Placing these extra small buzzers to context like that, and it becomes amazing that what so small technological device can do. But then considering that what a crickets already can do, or some small birds with their singing and it is even more amazing. As a fun another side mentioned story, few years ago we had a woodpecker living in our area, and one day it found that it can increase its calling pecking by flying to our house outdoor lamp, that is a big street lamp with big aluminum cover. And that think rattled like nothing. The woodpecker was crazy love with it as you could hear that pecking from over 7 km away. And it was not fun when you woke 5-6 AM to that melody as it sounded on otherside of the house like it was just next to your ear. Sadly woodpecker was required to be scared away, but she found a metal plate on top of the powerline poles just few hundred meters away and kept doing it there, luckily just less louder, but still. After one winter she didn't never return, but her "musical show" still lives on...
Unfortunately this mini is just too much weight and size for the flywoo baby nano 1s. It's also huge relative to the size of the baby nano 1s, I'm sitting here just trying to see if I could even fit it somewhere and it'd be a ridiuclously tight squeeze. The vifly buzzer is best suited for 3 inch quads and up honestly. I think if I was going to try to add a buzzer to my baby nano it would be a non battery backed one, and I'd try to find the smallest but loudest peizo buzzer i could get my hands on.
Erm, you do realize that a 6bB increase is doubling (!) the loudness, don‘t you? So that is not at all „a slight increase“, as you put it. Other than that, great video!
No, I did not realize that. I don't know anything about how dB is actually measured. Unfortunately, it doesn't sound to me at all like the loudness is doubled in actuality, but I would have to do a controlled distance test.
@@JohnCuppi Physics is a biatch 😆 As humans we cannot really sense those differences. In case of sound we can only tell for certain if something is too quiet to hear or if something is too loud for us to bare. Everything in between is a hit and miss. So we need a dB meter to be sure. A 110 bB can be heard significantly farther than a 100 dB. That much I know. But certainly not twice as far. Again, physics is a biatch 🤣
@@intensegamer7559 Thank you 🙂 I appreciate pointing out that I was wrong on this and explaining it. I’ll keep that in mind for next time. I’ve never had a physics or audio class, not even for my BS in information technology - sad I know!

Best reviewer on RUclips. In depth with all the specs. Good job as always John
Look at how small they are now. easy mounting. Great presentation John. Hope to see more.
Yes, great for small builds, and with the new FAA regs lighter hardware like this in the future will be important.
thanks for going at it with such depth! :)
Very cool John . And at $12.99 for the mini version it's well worth it ! Thanks brother !
Nice John . That's well done . Good to know that we can use it
You bet! Thanks!
Fantastic review mate
Happy birthday!
Thanks, John. This is going to be helpful to me in the future.
Glad it was helpful!
Always had a issue with the large ones going bad. I need to try the new mini. Very good review🤙👍
was it the battery going bad on the large ones?
@@JohnCuppi not sure. They were on freestyle quads.
Outstanding, thank you John.
Great review!. Been watching your vids. Would the mini be small enough for my flywoo baby nano? Or should I look elsewhere? 🤔
Unfortunately this mini is just too much weight and size for the flywoo baby nano 1s.

About the DB... "'it's only 10db", thats now how db works. 10db more is about TWICE as loud...
Yeah, I was unaware about that. Someone else already pointed it out in the comments. Still sounds very loud though for a mini version of this buzzer
@@JohnCuppiah ok :) I was just looking again to get a better idea of the size. But I have nog room for it in my Nazgul 😅
