The dogs hear them just fine
Like the description says, "Loud enough for the dogs to hear" (and I don't even have dogs). I bought these to make a headlight reminder because I'm tired of leaving my headlights on & draining the battery (old car). They're plenty loud enough to hear, and unpleasant enough sounding to train you to turn off the lights to avoid hearing them!

So far so good
I bought this for a low air pressure warning in my Kenworth at first I was skeptical about how loud they were but after install I was amazed these brothers were perfectly with just the right sound level to not be annoying yet you can clearly hear, very easy to install, such a good price got two for the price so now I have one as a backup, a function perfectly would buy again

Loud, but not enough.
Not as loud as I would like with 12 VDC. Its for a washer and dryer cycle complete remote alarm I designed since the laundry is in the garage. Had to replace with a different product.

Loudness depends on mounting surface
When holding this Hahiyo buzzer in my hand, the sound is barely audible. When pressing the buzzer against the car's chassis, the sound can be a about as loud the loudest cell phone ringer but it all depends on the mounting surface. IOW, the buzzer is vibrating the mounting surface.The problem is that there are just two tiny holes on the sides for mounting and one would have to drill tiny holes into the car's chassis to screw the buzzer to the chassis. I don't know how to drill tiny (maybe about 1/16 inch holes) into steel. Maybe gluing the buzzer might work but then the glue might dampen the sound or the buzzer might fall off due to the buzzer's vibration.Disappointed with the performance of this buzzer.EDIT: Decided to change from 3 stars to 1 star to let folks know how this buzzer actually works. It won't work for me.

Not too loud, not too soft... just right!
I also bought a limit switch to wire up a caution signal as a lower z-axis limit on my milling machine. Wired it so this buzzer sounds as I hit that limit.

Perfect Reminder Volume
Perfect volume for reminder if you are within about 30 - 40 feet. Not an alarm just a reminder buzzer with volume about the same as a cars oops you left your lights on or door open.
